Program to add, substract, multiply & divide two numbers

Write a program in C to add, substract, multiply & divide two numbers

Method - I (using 5 variables)

#include <stdio.h>

void main ()

{

int a,b,c,d,e,f;

clrscr();

printf ("Enter A: ");

scanf ("%d",&a);

printf ("Enter B: ");

scanf ("%d",&b);

c=a+b;

d=a-b;

e=a*b;

f=a/b;

printf ("\nSum is : %d",c);

printf ("\nSubtraction is : %d",d);

printf ("\nMultiplication is : %d",e);

printf ("\nDivision is : %d",f);

getch ();

}

Method - II (using 3 variables)

#include <stdio.h>

void main ()

{

            int a,b,c;

            clrscr();

            printf ("Enter A: ");

            scanf ("%d",&a);

            printf ("Enter B: ");

            scanf ("%d",&b);

            c=a+b;

            printf ("\nSum is %d",c);

            c=a-b;

            printf ("\nSubtraction is %d",c);

            c=a*b;

            printf ("\nMultiplication is %d",c);

            c=a/b;

            printf ("\nDivision is %d",c);

            getch ();

}
