2. Write a user defined function calc(), which will returns the sum, subtraction, multiplication, and division values of two variable locally declared in the main function.

 

#include<stdio.h>

#include<conio.h>

void calc(int *,int *);

void main()

{

    int no1,no2;

    clrscr();

    printf("enter 1st number: ");

    scanf("%d",&no1);

    printf("enter 2nd number: ");

    scanf("%d",&no2);

    calc(&no1, &no2);

    getch();

}

void calc(int *a, int *b)

{

    printf("\n\naddition : %d",*a + *b);

    printf("\nsubtraction: %d",*a - *b);

    printf("\nmultiplication: %d",*a * *b);

    printf("\ndivision: %d",*a / *b);

}

/*  output:

enter 1st number: 10

enter 2nd number: 5

addition : 15

subtraction: 5

multiplication: 50

division: 2
