Can anyone please tell me what is the difference between the properties of INT_MAX and LONG_MAX .
In this code CodeChef: Practical coding for everyone if i use INT_MAX it gives wrong answer , but on LONG_MAX it gives correct . What i know is both have same value then why such behaviour ?

int main()
{
    cout << "INT_MAX:" << INT_MAX << endl;
    cout << "LONG_MAX:" << LONG_MAX << endl;

Edit:

They might be the same on a 32-bit OS, though (like my Raspbian install).
