Error message:
error C4996: ‘itoa’: The POSIX name for this item is deprecated
the reason:
The new version of the old vs function itoa conducted security checks, so use the new version vs an error message appears, and the old version is no problem.
Solution:

_CRT_NONSTDC_NO_DEPRECATE #define
#define _CRT_SECURE_NO_WARNINGS
