Litleras

In C programming language, a “literal” is a value that is directly expressed in the source code of a program. It is a constant value that can be assigned to a variable or used in an expression.

For example, some common types of literals in C include

• Integer literals, such as 123 or -456.
• Floating-point literals, such as 3.14 or -0.001.
• Character literals, such as ‘a’ or ‘\n’.
• String literals, such as “Hello, world!” or “123”.
• Boolean literals, which can be either “true” or “false”.
• Null pointer literals, which are represented by the value “NULL”.

Literals can be used in many different ways in C programming, such as initializing variables, comparing values, or performing mathematical operations.
