Control Statements in C programming

The statements which alter the flow of execution of the program are called control statements. In the absence of control statements, the instruction or statements are executed in the same order in which they appear in the program. Sometimes, we may want to execute some statements several times. Sometime we want to use a condition for executing only a part of program. So, control statements enable use to specify the order in which various instruction in the program are to be executed.

There are two types of control statements:

1. Loops : for, while, do-while

2. Decisions: if, if...else, nested if....else, switch
