C++ - Programming Language

This course covers the basics of programming in C++.

While loops in C++ are used to execute a block of code repeatedly as long as a certain condition is true. Here’s an example of a program that uses a while loop to print the numbers from 1 to 10:

#include <iostream>

int main() {
    int i = 1;

    while (i <= 10) {
        std::cout << i << std::endl;
        i++;
    }

    return 0;
}

In this example, the program initializes a variable i to 1, and then enters a while loop with the condition i <= 10. The loop executes the code block inside the braces repeatedly as long as the condition is true. The code block simply prints the value of i to the console using std::cout, and then increments i by 1 using the ++ operator.

When i reaches 11, the condition i <= 10 becomes false and the program exits the loop. Finally, the program returns 0 to indicate successful execution.
