I'm getting the following errors:
ISO C++ forbids declaration of ttTreeInsert with no type
ISO C++ forbids declaration of ttTreeDelete with no type
ISO C++ forbids declaration of ttTreePrint with no type
prototype for int ttTree::ttTreePrint() does not match any in class ttTree
candidate is: void ttTree::ttTreePrint()
Here is my header file:
#ifndef ttTree_h
#define ttTree_h
class ttTree
{
public:
ttTree(void);
int ttTreeInsert(int value);
int ttTreeDelete(int value);
void ttTreePrint(void);
};
#endif
Here is my .cpp file:
#include "ttTree.h"
ttTree::ttTree(void)
{
}
ttTree::ttTreeInsert(int value)
{
}
ttTree::ttTreeDelete(int value)
{
}
ttTree::ttTreePrint(void)
{
}
Can anyone point out what is causing these errors? Thank you!
This question is related to
c++
function
class
constructor
declaration
You forgot the return types in your member function definitions:
int ttTree::ttTreeInsert(int value) { ... }
^^^
and so on.
Your declaration is int ttTreeInsert(int value);
However, your definition/implementation is
ttTree::ttTreeInsert(int value)
{
}
Notice that the return type int
is missing in the implementation. Instead it should be
int ttTree::ttTreeInsert(int value)
{
return 1; // or some valid int
}
