Size of dataTypes

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

Ans.

/*Program of shows of different data types size*/

#include<stdio.h>
#include<conio.h>
int main()
{
 int i;
 char ch;
 float f;
 long l;
 double d; 
 long double ld;
 printf("
Size of different data types as following");
 printf("
");
 printf("
Size of character ch is %d",sizeof(ch));
 printf("
Size of integer is %d",sizeof(i)); 
 printf("
Size of float is %d",sizeof(f));
 printf("
Size of long is %d",sizeof(l));
 printf("
Size of double is %d",sizeof(d));
 printf("
Size of long double is %d",sizeof(ld));
 getch();
 return 0;
}

 Output of the above programs:

    Size of different data types

 Size of character ch is 1
 Size of integer is 2

 Size of float is 4
 Size of long is 4

 Size of double is 8
 Size of long double is 10

NOTE:-The size of int,long are compiler dependent. The above sizes in this program for 16-bit compiler.
