C++ Exercises: Check two given integers, and return true if one of them is 30 or if their sum is 30

C++ Basic Algorithm: Exercise-3 with Solution

Write a C++ program to check two given integers, and return true if one of them is 30 or if their sum is 30.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

bool test(int x, int y)
        {
            return x == 30 || y == 30 || (x + y == 30);
        }        
        
int main() 
 {
  cout << test(30, 0) << endl;  
  cout << test(25, 5) << endl;  
  cout << test(20, 30) << endl;  
  cout << test(20, 25) << endl;    
  return 0;    
}

Sample Output:

1
1
1
0

Previous: Write a C++ program to get the absolute difference between n and 51. If n is greater than 51 return triple the absolute difference.
Next: Write a C++ program to check a given integer and return true if it is within 10 of 100 or 200.

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 )
