CString conversion to Const char*

CString str=_t ("This is my test program. ");
Get the length to convert to characters first
Const size_t strsize= (str. GetLength () +1) * *; The length of the wide character;
char * pstr= new char[strsize]; allocation of space;
size_t sz=0;
wcstombs_s (&sz,pstr,strsize,str,_truncate);

int N=atoi (const char*) pstr); The string has been converted from the original CString to the const char*

No such conversion will cause an error and cannot convert LPCTSTR or CString to const char*
