This program will demonstrate the working of a keyword long.
The long is a size modifier, indicated by keyword long, that may increase the size of a variable during declaration.
To understand this Program you should have the knowledge of following C programming topics:
- Data Types
- Constants
- Variables
- Input-Output (I/O)
Program to Demonstrate the Working of long
#include <stdio.h>
int main()
{
int a;
long b;
long long c;
double e;
long double f;
printf("Size of int = %ld bytes \n", sizeof(a));
printf("Size of long = %ld bytes\n", sizeof(b));
printf("Size of long long = %ld bytes\n", sizeof(c));
printf("Size of double = %ld bytes\n", sizeof(e));
printf("Size of long double = %ld bytes\n", sizeof(f));
return 0;
}
Output
Size of int = 4 bytes Size of long = 8 bytes Size of long long = 8 bytes Size of double = 8 bytes Size of long double = 16 bytes
In this program, the sizeof operator is used to find the size of int, long, long long, double and long double.
The long keyword cannot be used with float and char type variables.
