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