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

Goto Statement : The goto statement is used to alter the normal sequence of program execution by transferring control to some other part of the program unconditionally. Syntax : goto label; where the label is an identifier that is used to label the target statement to which the control is transferred. Control may be transferred to anywhere within the current function. The target statement must be labeled, and a colon must follow the label. Thus the target statement will appear as label:statement; Each labeled statement within the function must have a unique label, i.e., no two statement can have the same label. C – GOTO STATEMENT EXAMPLE PROGRAM : 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 #include<stdio.h> #include<conio.h> void main () { int   number ; clrscr (); printf ( “ www . ” ); goto x ; y : printf ( “.com” ); goto z ; x : printf ( “c prog
