Help me code mql4

[Nguyen Dang Giang]

I want to create a function similar to:

void  Print(    argument,     // first value    ...           // next values    );

or

uint  FileWrite(    int  file_handle,   // File handle    ...                 // List of recorded parameters    );

Example function:

bool checkCharacters(argument)
{

if(argument=="a") return(true);
if(argument=="a" && argument=="b") return(true);
if(argument=="a" && argument=="b" && argument=="c") return(true);
if(argument=="a" && argument=="b" && argument=="c" && argument=="d")r eturn(true);
if(argument=="a" && argument=="d") return(true);

return(false);}

}

Call function:

checkCharacters("a","d"); // result true

checkCharacters("a","a"); // result true

checkCharacters("a","b","z"); // result false


Thanks everyone!

Nguyen Dang Giang: I want to create a function similar to:

1. Variable arguments can't be done. Variable types can't be done.
   
2. Try default arguments

   bool checkCharacters(string a, string b="", string c="", string d="")

3. Or put the arguments in an array and pass that.

I want a dynamic parameter like the function Print().

Thanks whroeder1.
