print values in a bintree

**mengqing** · 05-13-2008

I have a struct named myStruct which has the following

Code:

strcut myStruct() {

int code
string keyval
}

I then loaded a txt file into myStruct

finally I inserted myStruct into a bintree object which I defined in another header file.

How do I print the data using the bintree??

For example if I was using a vector, I would use

Code:

cout << vector[i].code;

Also, I have a find function in my bintree.h

Code:

      
bool find(const dataType &findData, dataType &foundData) const {
         if (root == NULL) return false;
         else return root->find(findData, foundData);
}

How do I use it in my main program??

I am quite confused about the parameters that I need to pass to the function.

Thank You

You can overload operator<< to take an ostream& and a const myStruct&.

Incidentally, if you want to post a code snippet, it should be valid code, or obviously pseudocode. You might also want a more descriptive name than myStruct.

Hi, thx for the reply

Can you give me a example of how to that?

I am quite new to programming...
