What's the C++ equivalent of UINT32_MAX?

Question

In C99, I include stdint.h and that gives me UINT32_MAX as well as uint32_t data type. However, in C++ the UINT32_MAX gets d

Answer 1

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 .

cout << "Minimum value for int: " << numeric_limits::min() << endl;
cout << "Maximum value for int: " << numeric_limits::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::max() << endl;
