int main (){

char str[10];

cout<<"key: ";
cin.getline(str,10,'$');

char* e = perkey(str);



printArray(e);

return 0;
}

Re: Return Array from C++

Why are you hijacking a 3 year old thread? Can't you start a new thread with your new problem?

Re: Return Array from C++

function perkey() is using an unitilized pointer ptr Is the intent of that function to copy the contents of one string into another and return the pointer to the new string? Like strcpy() ? If so, then you need to call malloc() first to allocate memory for the new string.

[b]printArray[b] -- why are you using a loop to print each individual character when cout will print the entire string in one shot ?

And yes, you should have just started a new thread to ask your question.

[edit]Ok , ok so I failed to look at the datestamp of egemen's post -- three months old

And what makes you think Nichalson doesn't know how to program in C ?

Yeah, a 3 month bump, which in itself began as a bump of a 3 YEAR old thread.

I bet Jack knows how to spell his own name, regardless.

Can we close this now?

I don't think that's necessary -- it will probably die on its own. And DaniWeb rules don't permit closing a thread just because someone bumped it.
