Size of Operators

Program to use Size of Operators in c language

#include<stdio.h>
  int main()
  {
    int var;
    printf("size of int = %u\n",sizeof(int));
    printf("size of float = %u\n",sizeof(float));
    printf("size of var = %u\n",sizeof(var));
    printf("size of an integer constant = %u\n",sizeof(45));
    return 0;
  }
  

Output

size of int = 4
  size of float = 4
  size of var = 4
  size of an integer constant = 4
  

Steps Description

• Declare integer variable var
• printf inbuild function to display size of integer variable “var” using another inbuild function “size of()
• printf inbuild function to display size of float variable “var” using another inbuild function “size of()
• printf inbuild function to display size of”var” variable using another inbuild function size of()
• printf inbuild function to display size of in integer variable “var” using another function size of()
