C Data Types

A C data type declares the data type that a variable can hold.

C provides several built-in data types, including:

Data Type	Size	Description
int	2 or 4 bytes	Stores whole numbers, without decimals
float	4 bytes	Stores fractional numbers, which have one or more decimals.
char	1 byte	Stores a single letter/character/numbers
double	8 bytes	Stores fractional numbers, having one or more decimals.

Example


            #include
            <stdio.h>


            int main()

            {

                int integer
            = 40;

                float floating
            = 20.42;

                char character
            = 'D';



                printf("%d\n", integer);

                printf("%f\n", floating);

                printf("%c\n", character);

                return
            0;

            }
