Control Statements in C - Definition and Usage

• In C- Programming Control statements are used for defining and enabling the flow of program control;
  i.e., the order in which the instructions in a program must be executed.
• They make it possible to make decisions, to perform tasks repeatedly or to jump from one section of code to another.
• There are three types of control statements in C :
1. Decision making statements
2. Selection statements
3. Looping statements

Decision making statements :

• In C-Programming Decision making statements are used to specify the order in which statements are executed.
• There are three different types of decision making statements are,
1. If statement
2. If-else statement
3. Else-if statement

Selection statements :

• In C-programming the switch statement is used for multiple way selections that will branch into different code segments based on the value of a variable or expression.
• This expression or variable must be of integer data type.

Looping statements :

• In C-Programming the statements which appear in the source code only once but execute many times, are called loops.
• Repeated executions of certain statements are popularly known as loops.
• Almost all the programming languages support looping instructions.
• In C program there are three different types of looping statements : are
1. while
2. do while
3. for
