Compiler Error C2153

integer literals must have at least one digit

Hexadecimal and binary literals must contain at least one digit after the leading sequence (0x, 0X, 0b, or 0B), otherwise the trailing character may be incorrectly interpreted as a suffix or literal operator. See Integer literals for more information.

The following sample generates C2153:

// C2153.cpp
int main()
{
    int a = 0x;    // C2153
    int b = 0x0;   // OK

    int c = 0b;    // C2153
    int d = 0b0;   // OK
}
