*.H FILE IN C PROGRAM*

Write a calculator program that adds and subtracts. Prompt the user to enter two values and select an operation to perform. Incorporate a program with five modules and functions named as follows:

calc_driver.c - contains the function main() and the user interface

addition.h - contains the prototype for a function named add()

addition.c - contains the function definition for add()

subtraction.h - contains the prototype for a function named subtract()

subtraction.c - contains the function definition for subtract(

Explanation / Answer

Please find the required solution:

calc_driver.c - contains the function main() and the user interface:

#include <stdio.h>

#include "addition.h"
#include "subtraction.h"
#include "addition.c"
#include "subtraction.c"

int main()
{
int a,b;
printf("Calculater for enter 2 numbers");
scanf("%d",&a,&b);
printf("%d",sum(a,b));
printf("%d",sub(a,b));
return 0;
}

addition.h - contains the prototype for a function named add()

int add(int,int);

addition.c - contains the function definition for add()

#include "addition.h"

int add(int op1,int op2)
{
return op1+op2;
}

subtraction.h - contains the prototype for a function named subtract()

int sub(int,int);

subtraction.c - contains the function definition for subtract

#include "subtraction.h"

int sub(int op1,int op2)
{
return op1-op2;
}
