Write a c program, to find the addition of last two numbers using functions?

Question

Rohit wants to add the last digits of two given numbers.
For example, If the given numbers are 267 and 154, the output should be 11.

Below is the explanation -
Last digit of the 267 is 7
Last digit of the 154 is 4
Sum of 7 and 4 = 11

Write a program to help Rohit achieve this for any given two numbers.

Note: The sign of the input numbers should be ignored. i.e.
if the input numbers are 267 and 154, the sum of last two digits should be 11
if the input numbers are 267 and -154, the sum of last two digits should be 11
if the input numbers are -267 and 154, the sum of last two digits should be 11
if the input numbers are -267 and -154, the sum of last two digits should be 11

Answer 1

Its a simple homework problem -

#include<stdio.h>

int main() {
   int num1, num2, res;

   printf("\nEnter the two numbers : ");
   scanf("%d %d", &num1, &num2);

   res = sum(num1, num2);

   printf("\nAddition of two number is : ");
   return (0);
}

int sum(int num1, int num2) {
   int num3;
   num3 = num1 + num2;
   return (num3);
}
