CDate recognizes date literals and time literals but not numeric values. The best way to do this is to use Javas built-in Integer::parseInt method which takes a String argument and converts it to an int (line 10 in Fig. These built-in types describe variables that store single values of a predefined format and size. g++ treats returned string literal as const char pointer not const char array, cannot convert 'const char*' to 'LPCWSTR {aka const wchar_t*}', C++, Need Reason for error : cannot convert parameter 1 from 'char *' to 'const char *&', convert String to type const char* using Arduino.
