Find Path (Given source and destination) Path Cost (Given source and destination)

Hello i need help with my data structure project in c++:

the requirement is that I have to

1. Find Path (Given source and destination)
2. Path Cost (Given source and destination)

Using the image attached.

this is my program I have done so far:

Main.cpp

#include <iostream>
#include "Data.h"
using namespace std;

int main()
{
int ch;
Graph g(0);
cout << "Graph Operations" << endl << endl;
cout << "1-2 Create Graph" << endl;
cout << "[1] Adjacency List" << endl;
cout << "[2] Adjacency Matrix" << endl << endl;

cout << "3-4 Graph Traversal" << endl << endl;
cout << "[3] BFS Traversal" << endl;
cout << "[4] DFS Traversal" << endl << endl;

cout << "5-6 Find Path/Cost" << endl << endl;
cout << "[5] Find Path (Given source and destination) " << endl;
cout << "[6] Path Cost (Given source and destination) " << endl;

cout << "[0] Close Program" << endl;
cout << "Enter choice: ";
cin >> ch;
if (ch == 1)
{
g.addEdge(0, 5);
g.addEdge(0, 6);
g.addEdge(1, 3);
g.addEdge(1, 5);
g.addEdge(2, 4);
g.addEdge(3, 1);
g.addEdge(3, 2);
g.addEdge(3, 4);
g.addEdge(4, 0);
g.addEdge(4, 2);
g.addEdge(5, 0);
g.addEdge(6, 0);
g.addEdge(6, 3);
g.printGraph();
cout << endl << endl;

}
else if (ch == 2)
{
g.addEdge2(0, 5);
g.addEdge2(0, 6);
g.addEdge2(1, 3);
g.addEdge2(1, 5);
g.addEdge2(2, 4);
g.addEdge2(3, 1);
g.addEdge2(3, 2);
g.addEdge2(3, 4);
g.addEdge2(4, 0);
g.addEdge2(4, 2);
g.addEdge2(5, 0);
g.addEdge2(6, 0);
g.addEdge2(6, 3);
g.printGraph2();

}
else if (ch == 3)
{
int j;
cout << endl << "BFS Traversal..." << endl;
cout << "Input your prefered source / start: ";
cin >> j;
cout << endl;
g.BFS(j);
}
else if (ch == 4)
{
int k;
cout << endl << "DFS Traversal..." << endl;
cout << "Input your prefered source / start: ";
cin >> k;
cout << endl;
g.DFS(k);
}
cout << endl << endl;
}

can someone show me how to find the path and path cost
