The number of iterations to be performed in a for loop is already specified, whereas, in a while loop, the number of iterations is unknown.In this section, we will explain the difference between a for loop and a while loop. The majority of programming examples of loops only use a single statement inside the loop to control the iteration, but if the loop is only run once. While loops are easier to understand, for loops are generally more helpful in practice. There are two basic types of loops in most programming languages: the while loop and the for loop. Loops allow the programmer to tell a computer to repeat a block of code a particular number of times. Loops are a powerful and fundamental feature of almost any computer programming language. Otherwise, the condition becomes false.īreak % if the factor is found, not primeħ is prime Difference Between For Loop and While Loop The condition becomes true if the results contain a non-zero element or if the result is non-empty. The while loop repeatedly executes the program statement until the expression becomes false. The while loop has the following syntax:. They execute the statement continuously until a condition is met. While loops, nested loops and for loops are three of the most common types of loops. The majority of modern programming languages support loops, though their implementations. Loops are used by programmers to repeat the task using values, add numbers, repeat functions, etc.
