What are primary data types in C language?

‘C’ compilers support four fundamental data types. They are as follows −

• Integer
• Character
• Floating − point
• Double precision floating point

Primary Data Types

Integral data type

Integral data types are used to store whole numbers and characters.

It is further classified into two types −

• Integer data type.
• Character data type.

Integer data type

This data type is used to store whole numbers.

The integer storage are short int, int and long int in both signed and unsigned forms.

Character data type

Character data type is used to store characters only.

These characters are internally stored as integers.

Each character has an equivalent ASCII value.

For example, ‘A’ has ASCII value 65.

Floating - point Data type

Floating point data types are used to store real numbers.

float’ is used for 6 digits of accuracy.

‘double' is used for 12 digits of accuracy.

More than 12 digits, ‘long double’ is used.
