C is nearly a superset of C language (There are few programs that may compile in C, but not in C). Beginning with C programming: Structure of a C program After the above discussion, we can formally assess the structure of a C program. By structure, it is meant that any program can be written in this structure only.

- An if statement can be followed by an optional else statement, which executes when the Boolean expression is false. The syntax of an if.else statement in C programming language is −.
An if statement can be followed by an optional else statement, which executes when the Boolean expression is false.
Syntax
The syntax of an if...else statement in C programming language is −
If the Boolean expression evaluates to true, then the if block will be executed, otherwise, the else block will be executed.
C programming language assumes any non-zero and non-null values as true, and if it is either zero or null, then it is assumed as false value.

If...else if...else Statement
An if statement can be followed by an optional else if...else statement, which is very useful to test various conditions using single if...else if statement.
When using if...else if..else statements, there are few points to keep in mind −
An if can have zero or one else's and it must come after any else if's.
An if can have zero to many else if's and they must come before the else.
Once an else if succeeds, none of the remaining else if's or else's will be tested.
