C++ Exercises: Check if it is possible to add two integers to get the third integer from three given integers

C++ Basic Algorithm: Exercise-44 with Solution

Write a C++ program to check if it is possible to add two integers to get the third integer from three given integers.

Sample Solution:

C++ Code :

#include <iostream>

using namespace std;

bool test(int x, int y, int z)
        {
             return x == y + z || y == x + z || z == x + y;
        }
        
int main() 
 {
  cout << test(1, 2, 3) << endl; 
  cout << test(4, 5, 6) << endl; 
  cout << test(-1, 1, 0) << endl; 
  return 0;      
}

Sample Output:

1 
0
1

Previous: Write a C++ program to check whether a given string starts with "F" or ends with "B". If the string starts with "F" return "Fizz" and return "Buzz" if it ends with "B" If the string starts with "F" and ends with "B" return "FizzBuzz". In other cases return the original string.
Next: Write a C++ program to check if y is greater than x, and z is greater than y from three given integers x,y,z.

C++ Programming: Tips of the Day

What is the "-->" operator in C/C++?

--> is not an operator. It is in fact two separate operators, -- and >.

The conditional's code decrements x, while returning x's original (not decremented) value, and then compares the original value with 0 using the > operator.

To better understand, the statement could be written as follows:

while( (x--) > 0 )
