If Else Conditional Statements in C?

Conditional Statements (also called Conditions) are features of a programming language , Which allows it to perform actions depending upon some conditions provided by the programmer , This provides a “ DECIDING” functionality to a computer program and allows for flexible and easy code development.

Conditions are one of the most fundamental features of a C Program , You’ll see them In almost every useful C code.

In C the conditional statements generally follows the if - else if - else constructs

Code:

if(condition is true)
{
            do something;
}
else if(condition2 is true)
{
          do something;
}
else
{
            do something;
}

The ‘if’ statement

The if statement in C is quite similar to the ‘if’ statement in English , Consider the following examples :-

“If I am not tired I will surely go to work”
“if tomorrow is a holiday I will go to Mc Donald’s”

In the above statements we have a condition and on the basis of that condition we have a task associated with it, if the person is not tired he will surely go to work. Now let’s break this statement.

Condition : ‘if the person is not tired’
Task: He’ll go to work

An if statement in C is generally in the following form:-

Code:

if(condition is true)
    {
            do something;
    }

Between ‘(‘ and ‘)’ can be any valid C condition , and based on which the appropriate decision is taken.

The ‘Else if’ statement

The ‘else if’ statement in C is generally used when we need to compare more than one condition

The else if statement is generally used in following form :-

Code:

if(condition is true)
    {
            do something;
    }
    [COLOR="Red"]else if(condition2 is true)
    {
        
    }
    [/COLOR]else
    {
            do something;
    }

The else if block is executed if :-

1. All the preceding conditions failed and
2. The condition provided is true

The Else Statement

The else statement in C is generally in the following form

Code:

else
{
	Do something;
}

The else block is executed if the all the preceding conditions returned false.
