Data Types in C
Variables in C are associated with data type. Each data type requires an amount of memory and performs specific operations.
There are some common data types in C −
int − Used to store an integer value.
char − Used to store a single character.
float − Used to store decimal numbers with single precision.
double − Used to store decimal numbers with double precision.
The following table displays data types in C language −
| Data Types | Bytes | Range |
|---|---|---|
| short int | 2 | -32,768 to 32,767 |
| unsigned short int | 2 | 0 to 65,535 |
| unsigned int | 4 | 0 to 4,294,967,295 |
| int | 4 | -2,147,483,648 to 2,147,483,647 |
| long int | 4 | -2,147,483,648 to 2,147,483,647 |
| unsigned long int | 4 | 0 to 4,294,967,295 |
| signed char | 1 | -128 to 127 |
| unsigned char | 1 | 0 to 255 |
| float | 4 | 1.2E-38 to 3.4E+38 |
| double | 8 | 2.3E-308 to 1.7E+308 |
Here is the syntax of datatypes in C language,
data_type variable_name;
Here is an example of datatypes in C language,
Example
#include >stdio.h>
int main() {
// datatypes
int a = 10;
char b = 'S';
float c = 2.88;
double d = 28.888;
printf("Integer datatype : %d
",a);
printf("Character datatype : %c
",b);
printf("Float datatype : %f
",c);
printf("Double Float datatype : %lf
",d);
return 0;
}Here is the output,
Output
Integer datatype : 10 Character datatype : S Float datatype : 2.880000 Double Float datatype : 28.888000
