A control declaration is utilized in a programming language to govern the go with the flow of the program. They may be nothing however a keyword or statements which might be utilized in an application to switch the waft of manipulating to any other statement primarily based on the situation. Based on the given condition, it evaluates the result and executes the corresponding statements. Manage statements are the statement that controls the drift of the program to execute the piece of the code using diverse controls declaration like if assertion, if-else declaration, damage announcement, maintain assertion, for loop, whilst loop, do-at the same time as the loop. In this newsletter, we're going to speak about the various manipulate statements available in the c++ language with the assistance of examples.

Below is the different control statement in C++.

From the multiple conditions, a C++ Switch statement executes a single statement. It’s like a ladder statement if-else-if in C++.

//Code to execute if not all cases matched

cout << "To check the grade enter a number:";

To test the condition in C++ programming if the statement is been used. They are different types of if statement

C++ if the condition is evaluated by the argument. If the condition is valid, it is executed.

cout << "The Number you have Enter it is Even";

The statement C++ if-else also checks the condition. The declaration executes if the condition is true otherwise the block is carried out.

cout << "The Number you have Enter it is Odd";

The C++ if-else-if ladder declaration executes from multiple statements in one condition.

Syntax of if-else ladder statement in c++

// code should be executed if condition1 is true

// code should be executed if condition2 is true

// code should be executed if condition3 is true

Today we will discuss Control Statement in C++

Control Statement in C++

C provides us the feature of nesting one structure within another structure by using which, complex data types are created. For example, we may need to store the address of an entity employee in a structure. The attribute address may also have the subparts as street number, city, state, and pin code. Hence, to store the address of the employee, we need to store the address of the employee into a separate structure and nest the structure address into the structure employee. Consider the following program.

    printf("Enter employee information?\n");  

    scanf("%s %s %d %s",emp.name,emp.add.city, &emp.add.pin, emp.add.phone);  

    printf("Printing the employee information....\n");  

    printf("name: %s\nCity: %s\nPincode: %d\nPhone: %s",emp.name,emp.add.city,emp.add.pin,emp.add.phone);  

The structure can be nested in the following ways:

Here, we create two structures, but the dependent structure should be used inside the main structure as a member. Consider the following example.

As you can see, doj (date of joining) is the variable of type Date. Here doj is used as a member of the Employee structure. In this way, we can use the Date structure in many structures.

The embedded structure enables us to declare the structure inside the structure. Hence, it requires fewer lines of codes but it can not be used in multiple data structures. Consider the following example.

Below are the different examples of nested structure in C:

Example 1 – Initialization of nested structures:

Initialization of nested structures is possible at the time of declaration.

With this blog post we will discuss all types of nested structures in C, along with a brief description and some examples.

Overview of nested structures in C: their types and examples

Then, we're going to learn about the continued statement in C. This statement is majorly used in the case of iterators or in the case of looping. As the name formerly suggests, this statement makes sure that the law continues running after a particular statement is executed. It's used in the same way as the break statement, but the break statement would stop the prosecution of the circle or series of statements, but the continue statement in return would continue the prosecution of the law.

As already mentioned, the continue statement is used in loops. So the only syntax for the statement would be like above.

We can understand it better through a flow chart; let’s see it below.

As already known, any loop starts with a condition, and there would be two scenarios for it. One is the statement that has to be executed when a condition is true and others when it is false.

When a condition is false, it is going to obviously exit the loop.

And when a condition is true and have our continue statement, the iterator again goes back to the condition, and the above process continues.

If the condition does not have that continue statement, then the code below is executed.

Now let’s move on to use this statement in our program and see how it works.

int i=1;//initializing a local variable       

if(i==5){//if value of i is equal to 5, it will continue the loop    

As you can see, 5 is not printed on the console because loop is continued at i==5.

In such case, C continue statement continues only inner loop, but not outer loop.

int i=1,j=1;//initializing a local variable    

continue;//will continue loop of j only    

As you can see, 2 2 is not printed on the console because inner loop is continued at i==2 and j==2.

I hope you had a good time learning about the continue statement and understood where exactly we need this statement. We had bandied where we can use it and how it can help us in different programming scripts. Keep trying and playing around, continue statements in different scripts and have fun literacy.

The purpose of this blog post is to give you an understanding of the continue statement in C, its flow chart, and its example.

The easiest way to use the continue statement in C, along with  examples

Break Statement in C is a loop control proclamation that is utilized to end the loop. There are two utilizations and the given assertion is clarified underneath.

Inside a Loop: If the break statement is utilized inside a loop alongside the if statement then, at that point, if the condition turns out to be valid the loop is quickly ended and the following statement after the loop begins executing by the program control.

Inside a Switch Case: If Break Statement in C is utilized inside a switch case after each switch case then the break statement ends a case after executing the case.

Overall the break statements we utilized in the circumstances where we want to stop the loop execution in light of the condition or not certain how frequently the loop is to be repeated. If the break statements utilizing inside the settled loop, then, at that point, the break statement breaks the inward loop and starts executing the statement after the internal loop of the program control proceed to the external loop.

Examples to Implement Break Statement in C:

printf("The loop terminat at co = %d", co);

printf("Enter the option \“A\”, \“B\”, \“C\” or \“D\” :");

printf ( "You have not entered option A, B, C, or D, wrong input ");

Break statement inside the nested loop, in nested case, it breaks only the inner loop, but not outer loop, as can be understood by the code.

printf("outer = %d & inner = %d loop running\n",outer,inner);

So as in the above output, when outer = 3 & inner = 2 the inner loop break, and the execution continue to the outer loop for the 4th iteration.

Consider the following example to use the break statement inside the while loop.

During this blog post, we will gain a deeper understanding of break statements in C, we will learn about their flowcharts, as well as examples.

The switch statement in C is an alternative to the if-else-if ladder statement which allows us to execute multiple operations for the different possible values of a single variable called the switch variable. Here, we can define various statements in multiple cases for the different values of a single variable.

 code to be executed if all cases are not matched;    

Allow us to comprehend the progression of control portrayed in the flowchart above to acquire a superior comprehension of the progression of execution.

An articulation is passed with the switch statement, which is equivalent to one of the upsides of the cases. On the off chance that the worth isn't equivalent, the default case is executed. The worth of this articulation is then contrasted and the case identifier or the main case. If the principal case matches, then, at that point, the square of code related to the main case is executed. When the break is experienced, the execution stops, and you will leave the switch statement. In any case, if the case doesn't coordinate, the execution streams to the following case. If this case matches, then, at that point, the subsequent code block executes; in any case, the stream looks at the following case along these lines. At last, if no case matches, then, at that point, the default code block is executed.

This model portrays the utilization of the break statement in the switch. If the break statement isn't specified after the situation, the execution stream will go on until it experiences the break statement.

case 55:printf("This case also executes because there is no break ");

printf("The number is either 40 or 50 or 60");

printf("The number is greater than 60");}}

It is our goal in this blog post to introduce you to the switch statement in C,in which we will learn how it works,its flowchart,and examples of how it can be used.

Best uses of  switch statement in C  language and its examples

The goto statement is known as the jump statement in C. As the name suggests, goto is used to transfer the program control to a predefined label. The goto statement can be used to repeat some part of the code for a particular condition. It can also be used to break the multiple loops which can't be done by using a single break statement. However, using goto is avoided these days since it makes the program less readable and complicated.

The goto statement's working is extremely straightforward and can be utilized with exceptionally simple to present the control bouncing system in the program written in C. To work with the goto statement, we should characterize the goto statement, which should be possible utilizing the goto watchword followed by the label name. Once the goto statement is characterized, we should refer to the label name anyplace all through the program where the control must be hopped when the compiler witnesses the goto statement.

Let us understand how it works using an example.

Advantage & Disadvantage of goto statement:

using the goto statement you can alter the normal sequence of the program execution so it gives the power to jump to any part of the program.

It is always recommended not to use the goto statement as this reduces the readability of the program. It becomes difficult to trace the control flow of a program, making the program logic complex to understand. Using the goto statement is considered a poor programming practice. Any program written in C language can be written without the use of a goto statement. So try to avoid goto statement as much possible as you can.

Goto statement can be viewed as the bouncing statement, which makes the program stream in an ideal way, prompting the normal result. It accompanies its benefits and weaknesses. Contingent upon the program's size and intricacy, it relies upon whether it will exist there with a benefit or will prompt its restriction. It was acquainted in the C language with making the program move its control any place it needs to fabricate an effective working framework. Yet, later on, it was identified that the broad utilization of this statement was confusing the program.

At the point when we talk about composing little projects in the C language, it is exceptionally useful to utilize the goto statement and make the program work in the manner you need, however with regards to fostering the program that has hundreds and thousands of lines, it isn't recommended to utilize the goto statement. It will end by making the program excessively convoluted, and different designers can not get that. We want to deal with where we will utilize it to ensure that it very well may be utilized to simplify the program.

The purpose of this blogpost is to teach you about the goto statement in the C language, how to use it, examples, advantage and disadvantages of using it.
