1. If else statement in C. Sometimes you have a condition and you want to execute a block of code if condition is true and execute another piece of code if the same condition is false. This can be achieved in C using if-else statement. Previous Next.
2. C Nested if.else. The if.else statement executes two different codes depending upon whether the test expression is true or false. Sometimes, a choice has to be made from more than 2 possibilities. The nested if.else statement allows you to check for multiple test expressions and execute different codes for more than two conditions.
3. There's one 'else' in that sketch. It can't be that hard to figure out which 'if' it doesn't relate to. Hint: Too many ';'.

In the last tutorial we learned how to use if statement in C. In this guide, we will learn how to use if else, nested if else and else if statements in a C Program.

C If else statement

Syntax of if else statement:
If condition returns true then the statements inside the body of “if” are executed and the statements inside body of “else” are skipped.
If condition returns false then the statements inside the body of “if” are skipped and the statements in “else” are executed.

Example of if else statement

In this program user is asked to enter the age and based on the input, the if..else statement checks whether the entered age is greater than or equal to 18. If this condition meet then display message “You are eligible for voting”, however if the condition doesn’t meet then display a different message “You are not eligible for voting”.

Output:

Note: If there is only one statement is present in the “if” or “else” body then you do not need to use the braces (parenthesis). For example the above program can be rewritten like this:

C Nested If..else statement

When an if else statement is present inside the body of another “if” or “else” then this is called nested if else.
Syntax of Nested if else statement:

Example of nested if..else

Output:

C – else..if statement

The else..if statement is useful when you need to check multiple conditions within the program, nesting of if-else blocks can be avoided using else..if statement.

Lets take the same example that we have seen above while discussing nested if..else. We will rewrite the same program using else..if statements.

As you can see that only the statements inside the body of “if” are executed. This is because in this statement as soon as a condition is satisfied, the statements inside that block are executed and rest of the blocks are ignored.

Important Points:
1. else and else..if are optional statements, a program having only “if” statement would run fine.
2. else and else..if cannot be used without the “if”.
3. There can be any number of else..if statement in a if else..if block.
4. If none of the conditions are met then the statements in else block gets executed.
5. Just like relational operators, we can also use logical operators such as AND (&&), OR(||) and NOT(!).
