﻿ C Program: Add two integers, for same, return triple

# C Exercises: Compute the sum of the two given integer values. If the two values are the same, then return triple their sum

## C-programming basic algorithm: Exercise-1 with Solution

Write a C program to compute the sum of the two given integer values. If the two values are the same, then return triple their sum.

C Code:

#include <stdio.h>
int main(void){
printf("%d",test(1, 2));
printf("\n%d",test(2, 2));
}
int test(int x, int y)
{
return x == y ? (x + y)*3 : x + y;
}

Sample Output:

3
12

## C Programming: Tips of the Day

How does array [100] = {0} set the entire array to 0?

The behavior of this code in C is described in section 6.7.8.21 of the C specification (online draft of C spec): for the elements that don't have a specified value, the compiler initializes pointers to NULL and arithmetic types to zero (and recursively applies this to aggregates).

The behavior of this code in C++ is described in section 8.5.1.7 of the C++ specification (online draft of C++ spec): the compiler aggregate-initializes the elements that don't have a specified value.

Also, note that in C++ (but not C), you can use an empty initializer list, causing the compiler to aggregate-initialize all of the elements of the array:

char array[100] = {};

As for what sort of code the compiler might generate when you do this, take a look at this question: Strange assembly from array 0-initialization
