I am writing a Priority Queue program for a homework assignment and I am receiving the following error, which I do not fully understand. I need a help in order to solve the error, please.
The Error:
Undefined symbols for architecture x86_64:
"PriQueue<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > >::getPri()", referenced from:
_main in main.o
"PriQueue<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > >::getStr()", referenced from:
_main in main.o
"PriQueue<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > >::PriQueue()", referenced from:
_main in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Here is my program code:
#include <iostream>
#include <string>
#include <vector>
template <class T1>
class PriQueue
{
public:
PriQueue();
void enqueue(T1 str, int pri); //Adds to queue
void setStr(T1 newStr);
void setPri(int newPri);
T1 getStr();
T1 getPri();
void dequeue(T1 str, int pri); //Deletes from queue
void peek(T1 str, int pri); //Prints the the first in queue
void size(); //Prints how many in queue
//T1 printQ();
private:
T1 s;
T1 p;
};
template <class T1>
void PriQueue<T1>::enqueue(T1 str, int pri) //Adding an element to the queue
{
this->s = str;
this->p = pri;
}
template <class T1>
void PriQueue<T1>::setStr(T1 newStr)
{
this->s = newStr;
}
template <class T1>
void PriQueue<T1>::setPri(int newPri)
{
this->p = newPri;
}
template <class T1>
void PriQueue<T1>::dequeue(T1 str, int pri) //Removing an element from the front of the queue
{
}
template <class T1>
void PriQueue<T1>::peek(T1 str, int pri) //Returning a value at front of the queue (NOT removing it)
{
}
template <class T1>
void PriQueue<T1>::size() //Returning the number of items in the queue.
{
}
using namespace std;
int main()
{
PriQueue<string> que;
que.setStr("Hello");
que.setPri(4);
cout << que.getStr() << endl;
cout << que.getPri() << endl;
return 0;
}
