17. Explain various conditional statements in C language.

hey there

Conditional Statements in C programming are used to make decisions based on the conditions. Conditional statements execute sequentially when there is no condition around the statements.
the different types of conditional statements are available in C language.

1. if statement
2. if else
3. Nested if-else
4. if-else-if
5. switch

If statement

It is one of the powerful conditional statement. If statement is responsible for modifying the flow of execution of a program. If statement is always used with a condition. The condition is evaluated first before executing any statement inside the body of If.

if-else statement

The if-else statement in C language is used to execute the code if condition is true or false. It is also called two-way selection statement.

nested if...else

The nested if...else statement is used when a program requires more than one test expression. It is also called a multi-way selection statement. When a series of the decision are involved in a statement, we use if else statement in nested form.

if-else-if

The if-else-if statement is used to execute one code from multiple conditions. It is also called multipath decision statement. It is a chain of if..else statements in which each if statement is associated with else if statement and last would be an else statement.

Switch Statement

switch statement acts as a substitute for a long if-else-if ladder that is used to test a list of cases. A switch statement contains one or more case labels which are tested against the switch expression. When the expression match to a case then the associated statements with that case would be executed.

Dear Student,

There are different types of conditional statements are available in C language .

1. if-else
2. Nested if-else
3. if-else-if
4. switch

• If-else

when any condition is given in if block .. if the condition is true , the statements under if block will work .. otherwise the else block statement will execute.

• Nested if-else

If under any if statement , there is another (one or more) if statement/s are present .. then the scenario is called nested if-else .

• If-else-if

this condition works when we have to check more than one condition individually .

• Switch

This statement works for individual cases that are given at the time of building the code.
