WebJan 12, 2016 · Numeric literals cannot have short or unsigned short type. Of course in order to assign to bar, the value of the literal is implicitly converted to unsigned short. In your first sample code, you could make that conversion explicit with a cast, but I think it's pretty obvious already what conversion will take place. WebInteger literals frequently have prefixes indicating base, and less frequently suffixes indicating type.[1] For example, in C++0x10ULLindicates the value 16 (because hexadecimal) as an unsigned long long integer. Common prefixes include: 0xor 0Xfor hexadecimal(base 16); 0, 0oor 0Ofor octal(base 8); 0bor 0Bfor binary(base 2).
