Question

write a c program to create two functions for addition and substractio with in the function​

Answer 1

Answer:

#include<stdio.h>

// functions declaration

int add(int n1, int n2);

int subtract(int n1, int n2);

int multiply(int n1, int n2);

int divide(int n1, int n2);

// main function

int main()

{

 int num1, num2;

 printf("Enter two numbers: ");

 scanf("%d %d", &num1, &num2);

 printf("%d + %d = %d\n", num1, num2, add(num1, num2));

 printf("%d - %d = %d\n", num1, num2, subtract(num1, num2));

 printf("%d * %d = %d\n", num1, num2, multiply(num1, num2));

 printf("%d / %d = %d\n", num1, num2, divide(num1, num2));

 return 0;

}

// function to add two integer numbers

int add(int n1, int n2)

{

 int result;

 result = n1 + n2;

 return result;

}

// function to subtract two integer numbers

int subtract(int n1, int n2)

{

 int result;

 result = n1 - n2;

 return result;

}

// function to multiply two integer numbers

int multiply(int n1, int n2)

{

 int result;

 result = n1 * n2;

 return result;

}

// function to divide two integer numbers

int divide(int n1, int n2)

{

 int result;

 result = n1 / n2;

 return result;

}
