explain me the scenario when should i prefer do while over while loop in c programming

In C programming, the do while loop and the while loop are both used for iteration, but they have some key differences that make them suitable for different scenarios. The while loop is used when you want to execute a block of code repeatedly as long as a certain condition is true. It checks the condition before entering the loop, which means that the code inside the loop may not be executed at all if the condition is initially false. On the other hand, the do while loop is used when you want to execute a block of code at least once, regardless of the condition. The condition is checked at the end of the loop, so the code inside the loop will always be executed at least once. One scenario where you would prefer the do while loop over the while loop is when you need to prompt the user for input at least once, before checking a condition. For example, if you want to ask the user for a password and then check if it meets certain criteria, you would use a do while loop. Here is an example in C programming: “`c #include int main() { int password; do { printf(“Enter your password: “); scanf(“%d”, &password); } while (password != 1234); printf(“Access granted!n”); return 0; } “` In this example, the program will prompt the user to enter a password at least once, and then check if the password is correct. The code inside the do while loop will always be executed at least once, ensuring that the user is prompted for input. One verifiable fact about the do while loop is that it is guaranteed to execute the code inside the loop at least once, unlike the while loop which may skip the code entirely if the condition is initially false. This makes the do while loop useful in scenarios where you need to ensure that a certain block of code is executed at least once.
