In this Program, you’ll learn how to find Size of variable like int, float, double and char in C Language.
In this program to find Size of variable we declared 4 variables of type int, float, double and char. Then, the size of each variable is evaluated using sizeof operator.
To understand this example to find Size of variable, you should have the knowledge of following C programming topics:
- Constants
- Variables
- Data Types
- Input-Output
Program to Find the Size of a variable
#include <stdio.h>
int main()
{
int integerType;
float floatType;
double doubleType;
char charType;
// Sizeof operator is used to evaluate the size of a variable
printf("Size of int: %ld bytes\n",sizeof(integerType));
printf("Size of float: %ld bytes\n",sizeof(floatType));
printf("Size of double: %ld bytes\n",sizeof(doubleType));
printf("Size of char: %ld byte\n",sizeof(charType));
return 0;
}
Output
Size of int: 4 bytes Size of float: 4 bytes Size of double: 8 bytes Size of char: 1 byte
In this program, 4 variables integerType, floatType, doubleType and charType are declared having int, float, double and char type respectively.
Then, the size of each variable is ascertained using sizeof operator.
