while and do-while loop in C++

Loops are fundamental constructs in programming that allow us to repeat a block of code multiple times. In C++, two commonly used loop structures are the while loop and the do-while loop. In this blog post, we’ll dive into these loops, understand their syntax, and provide examples to illustrate their usage.

The While Loop

The while loop is a conditional loop that repeats a block of code as long as a specified condition is true. Here’s the basic syntax:

while (condition) {
    // Code to be executed while the condition is true
}

Counting from 1 to 10

#include <iostream>int main() {
    int i = 1;
    while (i <= 10) {
        std::cout << i << " ";
        i++;
    }
    return 0;
}

In this example, the while loop continues to execute as long as i is less than or equal to 10. It prints numbers from 1 to 10.

The Do-While Loop

The do-while loop is similar to the while loop, but it guarantees that the loop body will be executed at least once before checking the condition for continuation.
