Not sure about uint32_t, but for fundamental types (bool, char, signed char, unsigned char, wchar_t, short, unsigned short, int, unsigned int, long, unsigned long, float, double and long double) you can use the numeric_limits templates via #include <limits>.
cout << "Minimum value for int: " << numeric_limits<int>::min() << endl;
cout << "Maximum value for int: " << numeric_limits<int>::max() << endl;
If uint32_t is a #define of one of the above than this code should work out of the box
cout << "Maximum value for uint32_t: " << numeric_limits<uint32_t>::max() << endl;
