How can I include strings in conditional statements...in C++ ?

C++ if Statement

The syntax of the if statement is:

if (condition) {
  // body of if statement
}

The if statement evaluates the condition inside the parentheses ( ).

• If the condition evaluates to true, the code inside the body of if is executed.
• If the condition evaluates to false, the code inside the body of if is skipped.

Example 1: C++ if Statement

// Program to print positive number entered by the user
// If the user enters a negative number, it is skipped

#include <iostream>
using namespace std;

int main() {

  int number;

  cout << "Enter an integer: ";
  cin >> number;

  // checks if the number is positive
  if (number > 0) {
    cout << "You entered a positive integer: " << number << endl;
  }

  cout << "This statement is always executed.";

  return 0;
}

Output 1

Enter an integer: 5
You entered a positive number: 5
This statement is always executed.

When the user enters 5, the condition number > 0 is evaluated to true and the statement inside the body of if is executed.

Output 2

Enter a number: -5
This statement is always executed.

When the user enters -5, the condition number > 0 is evaluated to false and the statement inside the body of if is not executed.

#include <iostream>

using namespace std;

int main() {

  int number;

  cout << "Enter an integer: ";

  cin >> number;

  // checks if the number is positive

  if (number > 0) {

    cout << "You entered a positive integer: " << number << endl;

  }

  cout << "This statement is always executed.";

  return 0;

}
