C program to find size of DATA TYPES

Q.) Write a simple program to find the size of different basic data types in C  

#include<stdio.h>

 #include<conio.h>

int main( ) 

{

int i;

char ch ;

float f;

long l;

printf("\n\t Size of different data types as following \n") ;

printf("\n Size of character ch is %d", sizeof(ch));

printf("\n Size of integer i is %d", sizeof(i));

printf("\n Size of float f is %d", sizeof(f));

printf("\n Size of long l is %d", sizeof(l));

return 0;

}
