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.
