Answer 2

The Standard Data Types in C programming language is as follows:

• Char

It is one of the most basic data types in C that stores a single character and takes a single byte of memory in almost all compilers.

• Int

This is also one of the basic data types and is used to store an integer.

• Float

This data type is used to store decimal numbers that can be defined as numbers with floating-point value with single precision.

• Double

This data type is used to store decimal numbers with double precision.
