Explanation

When using atoi() with an apstring variable (a string class commonly used in some programming courses), you must convert the apstring to a standard C-style string using the .c_str() method. The atoi() function expects a null-terminated C-string (const char*), not a C++ string object. This conversion is necessary for the function to work correctly.
