#include<stdio.h>

void main()

{

int x;

char y;

float z;

printf("x=%d\n",sizeof(x));

printf("int =%d\n",sizeof(int));

printf("y=%d\n",sizeof(y));

printf("char =%d\n",sizeof(char));

printf("z=%d\n",sizeof(z));

printf("float =%d\n",sizeof(float));

}

OUTPUT:

x=2

int =2

y=1

char=1

z=4

float=4
