Difference between while and do while

NIELIT O Level January 2016 Solve paper

Q 7 b.(ii) while and do..while loops

Iteration statements allow the set of instructions to execute repeatedly till the condition doesn’t turn out false. The Iteration statements in C for while loop and do while loop. These statements are commonly called loops. Here, the main difference between a while loop and do while loop is that while loop check condition before iteration of the loop, whereas do-while loop, checks the condition after the execution of the statements inside the loop.

BASIS FOR COMPARISON	WHILE	DO-WHILE
Syntax	while ( condition) { statements; //body of loop }	do{ . statements; // body of loop. . } while( Condition );
Controlling Condition	In 'while' loop the controlling condition appears at the start of the loop.	In 'do-while' loop the controlling condition appears at the end of the loop.
Iterations	The iterations do not occur if, the condition at the first iteration, appears false.	The iteration occurs at least once even if the condition is false at the first iteration.
