Answer:

Loop Statements in C execute the sequence of statements many times until the stated condition becomes false.

‘C’ programming language provides three types of loop constructs:

• For Loop

• While Loop

• Do-while Loop :

Explanation:

• The versatility of the computer lies in its ability to perform a set of instructions repeatedly that involves repeating some portion of the program either a specified number of times or a particular condition is being satisfied. This is done through a loop control structure.

• The loop statements continue while a condition is true.
• When the condition becomes false, the loop ends and the control      passes to the statements following the loop.

• In C language, A loop consists of two parts, a body of a loop and a control statement. The control statement is a combination of some conditions which control  the execution of the body of the loop  until the specified condition becomes false.

• Depending upon the position of a control statement in a program, Loop in C is classified into two types:

                  1. Entry controlled loop

                  2. Exit controlled loop

• In an entry control loop , a condition is checked before execution of the body of a loop.

• In an exit controlled loop, a condition is checked after the execution of the body of a loop.

‘C’ programming language provides three types of loop constructs:

• For Loop : In a for loop, the initialization of loop counter  is performed only once, then the condition tests and compares the counter to a fixed value after each iteration and stopping the loop when condition is false .

• While Loop : In while loop, a condition is evaluated before processing a body of the loop. If a condition is true then  only the body of a loop is executed.

• Do-while Loop : In a do-while loop, the condition is always executed after the execution of the body of a loop. It is also called an exit-controlled loop.
