Control Statements in C with Examples

Control Statements in C

In C programming language, Control Statements are used to execute/transfer the control from one part of the program to another depending on a condition. These statements are also called conditional statements.

Types of Control Statements in C

In C Programming, There are mainly two types of Control Statements:
1. if-else statement
2. switch statement

if-else statement:

if-else statement is used to execute a statement block or a single statement depending on the value of a condition. It has the following syntax:

if(condition)
{
- - - - - - - - -
- - - - - - - - -
}
else

- - - - - - - - -

- - - - - - - - -
}

Nested if-else Statement:

An if statement may have another if statement in the < true block > and < false block >. It is the nesting of an if statement within another if statement and the nesting of an if statement with an else statement. This compound statement is called a Nested if-else Statement.

if(condition 1)
