C++ Loops

Sometimes it is necessary for the program to execute the statement several times, and C++ loops execute a block of commands a specified number of times until a condition is met. In this chapter, you will learn about all the looping statements of C++ along with their use.

What are Loops in C++?

There may arise some situations during programming where programmers need to execute a block of code several times (with slight variations sometimes). In general, statements get executed sequentially with a C++ program, one statement followed by another. C++ provides statements for several control structures along with iteration/repetition capability that allows programmers to execute a statement or group of statements multiple times.

C++ supports following types of loops:

All are slightly different and provides loops for different situations.

C++ Loop Control Statements

Loop control statements are used to change the normal sequence of execution of the loop.

StatementSyntaxDescription
break statementbreak;Is used to terminate loop or switch statements.
continue statementcontinue;Is used to suspend the execution of current loop iteration and transfer control to the loop for the next iteration.
goto statementgoto labelName;labelName: statement;It transfers current program execution sequence to some other part of the program.
