C++ Exercises: Check a given integer and return true if it is within 10 of 100 or 200

C++ Basic Algorithm: Exercise-4 with Solution

Write a C++ program to check a given integer and return true if it is within 10 of 100 or 200.

Sample Solution:

C++ Code :

#include <iostream>

using namespace std;

bool test(int x)
        {
              if(abs(x - 100) <= 10 || abs(x - 200) <= 10)
                return true;
            return false;
        }
        
int main() 
 {
  cout << test(103) << endl;  
  cout << test(90) << endl;  
  cout << test(89) << endl;  
  return 0;    
}

Sample Output:

1
1
0

Previous: Write a C++ program to check two given integers, and return true if one of them is 30 or if their sum is 30.
Next: Write a C++ program to create a new string where 'if' is added to the front of a given string. If the string already begins with 'if', return the string unchanged.

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 )
