I can do a sort of combination like my current code. I can stoi the month value really easy and remove the year value. If I could store that year to an integer before removing it then I would be left with 1-1 or 01-01 and I still don't know how to get rid of the first two...
what we still have to know is: When does an error occur? It does occur if you expect an integer, (like in your case) but the first chars in your string are no numbers, but some alphabetic chars. In other words, if the Stream cant extract what you wish for, because we cant match...
Edit & run on cpp.sh '12345' => converted to integer 12345 '12345xyz' => converted to integer 12345 the first 5 characters were converted 'xyz12345' => no conversion could be performed '123456789012345' => converted value would be out of the range of an int ...
The function returns a pointer to an integer, i.e. a memory location that points to an integer type. Locally, we've declared our local intPtr as a pointer to an integer. As these two match, there's no need for a reference operator. Feb 6, 2013 at 7:13pm Ch1156 (2010) Ok ...
