C Data Type

Data types

In C program, before storing a data in memory (Store) and using that data (Use), we must give its data type.

Integer Data type:

It is an integer data type. It is used to store an integer. Its size is 4 bytes.

If we use an integer data type in the program it will take 4 bytes in memory.

Eg:

0,1,4,5,-3,-2 can only return integers like this.

Float data type:

Using this you can store only numbers with dot(.) in memory.This also takes 4 bytes to store a value in memory.

Eg:

1.5,3.67,4.55,.4.77

Such fractional numbers should be given.

Double data type:

This also can store only dotted numbers in memory. It takes 8 bytes in memory.

Eg:

1784.5786,-4758.6788474.

Void data type:

It is an incomplete data type. Its memory size is 1 bytes.

Eg:

void display()

The display() function does not return any value to the called function after it has completed its work.

char data type:

Only one character can be stored in it. We have to give the given character inside single quotes. It takes 1 bytes to store one character in memory.

Eg:

'a','c','g','#'

This is how we should give character.
