 C Program-Find Size of int, float, double and char of System

Syntax of size of Operator:-

 temp = sizeof(operand);
/* Here, temp is a variable of type integer,i.e, sizeof() operator
   returns integer value. */

 

Source Code :-)

/* This program computes the size of variable using sizeof operator.*/ 

#include <stdio.h> 

int main()

{ 

int a; 

float b; 

double c; 

char d; 

printf("Size of int: %d bytes\n",sizeof(a)); 

printf("Size of float: %d bytes\n",sizeof(b)); 

printf("Size of double: %d bytes\n",sizeof(c)); 

printf("Size of char: %d byte\n",sizeof(d)); 

return 0; 

}

OUTPUT :-)

Size of int: 4 bytes
Size of float: 4 bytes
Size of double: 8 bytes
Size of char: 1 byte
