Write a program to find the size of basic data types of C

#include<stdio.h>
#include<conio.h>
int main()
{
float f;
int i;
double d;
char c;
printf("the size of integer is %d",sizeof(i));
printf("\nthe size of float is %d",sizeof(f));
printf("\nthe size of double is %d",sizeof(d));
printf("\nthe size of character is %d",sizeof(c));
}
