C++ - Do while loop

In C++, the do/while loop is another type of loop that allows you to repeatedly execute a block of code until a given condition becomes false. The main difference between the do/while loop and the while loop is that the do/while loop executes the code block at least once, regardless of the condition. Here's the syntax of the do/while loop:

do {
    // Code to be executed
} while (condition);

The code block is executed first, and then the condition is checked. If the condition is true, the loop continues, and the code block is executed again. This process repeats until the condition becomes false.

int count = 1;
do {
    std::cout << "Count: " << count << std::endl;
    count++;
} while (count <= 5);

In this example, the do/while loop is similar to the while loop mentioned earlier, but it guarantees that the code block will execute at least once before checking the condition. The loop continues to execute as long as the count variable is less than or equal to 5.

It's important to note that the loop control variable (count in this example) must be initialized before the do/while loop to avoid undefined behavior. Otherwise, the initial value of the variable would be indeterminate.
