Detailed explanation-1: -for loops are commonly used to run code a set number of times. Also, you can use break to exit the loop early, before the condition expression evaluates to false .
Detailed explanation-2: -A “While” Loop is used to repeat a specific block of code an unknown number of times, until a condition is met. For example, if we want to ask a user for a number between 1 and 10, we don’t know how many times the user may enter a larger number, so we keep asking “while the number is not between 1 and 10".
Detailed explanation-3: -A while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement.
Detailed explanation-4: -The while loops statement in C allows you to execute the same block of code over and again until a condition is fulfilled. In C programming, a while loop is the simplest fundamental loop. While loops have only one control condition and run as long as it is true.
Detailed explanation-5: -The name for-loop comes from the word for. For is used as the keyword in many programming languages to introduce a for-loop.
