compiler error

[dc83]

I got this compiler error
"numeric constant contains digits beyond the radix"

in reference to this section of code
"if (month = 08)"
and I don't know why.

I don't get errors for anything else just the "if (month = 08)" and also for the 09. works for 01-07 though and 10-12.

The "0" in front implies octal notation. 8 is not a "digit" of the octal system. Just do not use a preceding 0 when you intend base 10.

ok thanks. What if the user inputs an 09 though will that be recognized as 9?

This all depends on how you read in the input. If you are using the default cin iostream and stream into an integer, it will read it in as a decimal value.

Depends pretty much on current stream flags.

If you want to be absolutely sure,


#include <iostream>
int main() { int month; std::cin.setf(std::ios_base::dec,std::ios_base::basefield); std::cin >> month; std::cout << month; }
