How to use Loops in C In any programming language including C, loops are used to execute a set of statements repeatedly until a particular condition is satisfied. How it Works The below diagram depicts a loop execution, As per the above diagram, if the Test Condition is true, then the loop is executed, and if it is false then the execution breaks out of the loop. After the loop is successfully executed the execution again starts from the Loop entry and again checks for the Test condition, and this keeps on repeating. The sequence of statements to be executed is kept inside the curly braces { } known as the Loop body . After every execution of the loop body, condition is verified, and if it is found to be true the loop body is executed again. When the condition check returns false , the loop body is not executed, and execution breaks out of the loop. Types of Loop There are 3 types of Loop in C language, namely: while loop for loop do while loop while
