SIZE OF INTEGER DATATYPE
In this tutorial we are going to see how to do a size of an integer using normal C program.
We are using stdio.h to get the standard input and output of the program.
The size of is a unary operator that returns the size of data (constants, variables, array, structure, etc).
Here we are declaring variables for the integers short , long , long long ,etc….
And now in print statement we are giving a string sizeof the short or integer.
We are declaring %d to declare the sizeof integer in bytes.
We use \n to initiate new line and we are using sizeof to enter the value of the given integer.
#include <stdio.h>
int main() {
short a;
long b;
long long c;
short int d;
unsigned int e;
long int f;
long long int g;
unsigned long int h;
unsigned long long int i;
signed char j;
unsigned char k;
long double l;
printf("size of short = %d bytes\n", sizeof(a));
printf("size of long = %d bytes\n", sizeof(b));
printf("size of long long = %d bytes\n", sizeof(c));
printf("size of short int = %d bytes\n", sizeof(d));
printf("size of unsigned int
= %d bytes\n", sizeof(e));
printf("size of long int = %d bytes\n", sizeof(f));
printf("size of long long int = %d bytes\n", sizeof(g));
printf("size of unsigned long int
= %d bytes\n", sizeof(h));
printf("size of unsigned long long int = %d bytes\n",
sizeof(i));
printf("size of signed char = %d bytes\n", sizeof(j));
printf("size of unsigned char = %d bytes\n", sizeof(k));
printf("size of long double = %d bytes\n", sizeof(l));
