program to find the size of a variable

In this program we declare 4 type of variables which is integer , float , double , char. hten we find the size of variables using size of operator.

1. Program to find the size of variables in c language.

#include<stdio.h>
#include<conio.h>

void main()
{
   int int_type;
   float float_type;
   double double_type;
   char char_type;

   clrscr();

       //size of operator is used to find the value of variables
    printf("Integer size is%d byte\n",sizeof(int_type));
    printf("Float size is%f byte\n",sizeof(float_type));
    printf("Double size is %ld byte\n",sizeof(double_type));
    printf("Integer size is%c byte\n",sizeof(char_type));

 
   getch();
}



2. Program to find size of variables in c++ language.

#include<iostream.h>
#include<conio.h>

void main()
{
   int int_type;
   float float_type;
   double double_type;
   char char_type;
   clrscr();
 
    cout<<"Integer size is\n"<<sizeof(int_type);
    cout<<"Float size is\n"<<sizeof(float_type);
   cout<<"Double size is\n"<<sizeof(double_type);
   cout<<"Char size is\n"<<sizeof(char_type);

  getch();
}
