I'm trying to implement a linked list but get an error when compiling:
intSLLst.cpp:38: error: ‘intSLList’ has not been declared
intSLList looks like it's been declared to me though so I'm really confused.
intSLLst.cpp
#include <iostream>
#include "intSLLst.h"
int intSLList::deleteFromHead(){
}
int main(){
}
intSLLst.h
#ifndef INT_LINKED_LIST
#define INT_LINKED_LIST
#include <cstddef>
class IntSLLNode{
int info;
IntSLLNode *next;
IntSLLNode(int el, IntSLLNode *ptr = NULL){
info = el; next = ptr;
}
};
class IntSLList{
public:
IntSLList(){
head = tail = NULL;
}
~IntSLList();
int isEmpty();
bool isInList(int) const;
void addToHead(int);
void addToTail(int);
int deleteFromHead();
int deleteFromTail();
void deleteNode(int);
private:
IntSLLNode *head, *tail;
};
#endif
You're using a lower case i
int intSLList::deleteFromHead(){
}
should be
int IntSLList::deleteFromHead(){
}
Names in c++ are always case sensitive.
intSLList
isn't the same as IntSLList
. This isn't Pascal. C++ is case sensitive.
