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 )
