Write a C 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

Explanation:

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.
