C PROGRAM TO CALCULATE SUBTRACTION AND ADDITION(USING FUNCTION)

Write a program to calculate the Subtraction and addition of two numbers by using functions.

#include<stdio.h>

#include<conio.h>

int sum(int, int);

int sub(int, int);

int main()

{

int a, b, c, d;

clrscr();

printf(" Enter the two numbers");

scanf("%d%d",&a,&b);

c=sum(a, b);

d=sub(a, b);

printf("The sum of the number is %d and the difference is %d",c,d);

getch();

return(0);

}

int sum(int x, int y)

{

int z;

z=x+y;

return(z);

}

int sub(int x, int y)

{

int z;

z=x-y;

return(z);

}

OUTPUT:

Enter the two numbers 8 4

The sum of the number is 12 and the difference is 4
