MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -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-2: -Fixed loop-This is where the loop repeats a sequence of code a set number of times.

Detailed explanation-3: -A loop, in programming, is a technique that allows you to repeat one or more instructions without having to retype the same set of instructions multiple times.

Detailed explanation-4: -Using range() with For Loop A for loop repeats a sequence until a condition is met. If you’re familiar with other languages, you can also compare that the for loop offered by Python is more similar to the ‘for-each’ loop in other languages.

Detailed explanation-5: -The repeat / until loop is a loop that executes a block of statements repeatedly, until a given condition evaluates to true . The condition will be re-evaluated at the end of each iteration of the loop, allowing code inside the loop to affect the condition in order to terminate it.
