In programming, a loop is a programming structure that repeats a set of instructions until a specified condition is met. Loops are commonly used in programming because, compared to repeated lines of code, they save time, reduce error, and are easy to read.

Loops can be written as while loops, do-while loops, and for loops. while loops iterate until a condition is met. a++; do-while loops are while loops that initially execute the body once before checking the condition. printf("not true!"); for loops complete a set number of iterations before meeting a condition. printf("Hello!");

For Loops For loops are useful when we know ahead of time how many times we want to repeat something. We declare a loop variable (or loop counter) and in each iteration we increment it until we reach the number of times we want to execute some code. for (int i = 0; i …
