C Program to Demonstrate the Working of Keyword long
The long is a size modifier, indicated by keyword long, that may increase the size of a variable during declaration. This program will demonstrate the working of long keyword.
To understand this example, you should have the knowledge of following C programming topics:
- C Programming Data Types
- C Programming Constants and Variables
- C Programming Input Output (I/O): printf() and scanf()
Example: 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 andlong double.
The long keyword cannot be used with
float and char type variables.
