﻿ C++ : Check a integer is within 10 of 100 or 200

# 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
```

## 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 )
