Help !

Hello
how do you write a program using a link list for a particular stack that will store data of the type char. Calling a member function named pushing to push an item onto the stack and a member function named popping to pop the item off the stack.

a struct named StackFrame and a pointer named link as well as a typedef statement, a class named Stack , copy constructor, destructor and a bool; empty() method.

You need to prompt for a word from the keyboard and then show the word written backwards, you also need to give the user the chance to try again.

show us what you have so far. We won't do your homework for you, but we are glad to offer help when you are stuck.

this is what i have so far but having trouble with my int main()

first of all, when you post code, please enclose it in code tags. Click on the "<>" button in the Format options and then past your code between the opening and closing tags.

Second, on first look, your class looks pretty good. You have one problem, though, with data types. Your stack pushes and pops ints, but your Stackframe structure stores a char.

You don't really explain what your problem is, besides you are having problems with main(). You really need to be more explicit with what problems you are having (can't compile, won't run at all, unexpected output, core dump, etc.). But I think I see your problem. You define word to be of type char, so you store a single character in the stack ad then display it, not the whole word you are expecting. Is that what you are seeing?

What trouble are you having with main()?
