C Programming language

In this section we are going to provide The following Data Type in C.

Integer Type

Integer variable is whole number variable n the range of that variable is machine dependent. A programmer should always take care f the range of that variable n also take care of the storage capacity. Integer can be signed and unsigned.

There are three classes of integer in c are Short int, integer, long int. the difference between these classes only of its range.

Example

int main( )
{
int a=
10 ; // a contain integer type value.
return a;
}

Float Type

Floating point variable represent a real number with 6 digits precision. Float keyword use for floating point number. The accuracy of floating point number is insufficient so use double .double is same as floating point number but range of precision is longer then the float.

To extend the precision further we can use long double which consumes 80 bits of memory space.

Example

float main( )
{
float a=10.344 ; // a contain float type value.
return a;
}

char Type

The capability of char is holding one character in the local character set. Characters are usually stored in 8 bits of internal storage or can say that one byte. In the char the qualifier signed or unsigned can be explicit applied. While unsigned characters have values between 0 and 255, signed characters have values from –128 to 127.

The character set in C Language can be grouped into the following categories.

1. Letters
2. Digits
3. Special Characters
4. White Spaces
