What is the maximum value for an int32?

Answer 1

The easiest way to remember is to look at std::numeric_limits< int >::max()

For example (from MSDN),

// numeric_limits_max.cpp

#include 
#include 

using namespace std;

int main() {
   cout << "The maximum value for type float is:  "
        << numeric_limits::max( )
        << endl;
   cout << "The maximum value for type double is:  "
        << numeric_limits::max( )
        << endl;
   cout << "The maximum value for type int is:  "
        << numeric_limits::max( )
        << endl;
   cout << "The maximum value for type short int is:  "
        << numeric_limits::max( )
        << endl;
}
