c++ – warning: control reaches end of non-void function [-Wreturn-type]
You just need to
return from the main function at some point. The error message says that the function is defined to return a value but you are not returning anything.
/* .... */ if (Date1 == Date2) fprintf (stderr , Indicating that the first date is equal to second date.n); return 0; }
You can also use
EXIT_SUCCESS instead of
return 0;. The macro
EXIT_SUCCESS is actually defined as zero, but makes your program more readable.
