Sample C Program To Specify Size Of Commonly Used Data Types.

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

main ()
{

clrscr();
printf ("\n An int is %d bytes", sizeof (int));
printf ("\n A char is %d bytes", sizeof (char));
printf ("\n A short is %d bytes", sizeof (short));

printf ("\n A long is %d bytes", sizeof (long));
printf ("\n A float is %d bytes", sizeof (float));
printf ("\n A double is %d bytes", sizeof (double));

printf ("\n An unsigned char is %d bytes", sizeof (unsigned char));
printf ("\n An unsigned int is %d bytes", sizeof (unsigned int));
return 0;

}

OUTPUT:

An int is 2 bytes
A char is 1 bytes
A short is 2 bytes
A long is 4 bytes
A float is 4 bytes
A double is 8 bytes
An unsigned char is 1 bytes
An unsigned int is 2 bytes

Sample C Program To Input & Multiply Two Numbers.

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

void main()
{

clrscr();
int a, b, c;

printf(" Enter the numbers to be multiplied: ");
scanf(" %d %d ", &a, &b);
c = a * b;

printf(" The product of the numbers is: %d ",c);
getch();

}

OUTPUT:

Enter the numbers to be multiplied: 10
5
The product of the numbers is: 50
