What are the ways to pause console page after run in C++?

Well, this is my code and the graph.show() function shows a graph which I have created before so please look at the code and check that I must use your solution here:

Graph G(nodes.size(), false);

     for(nit = nodes.begin(); nit != nodes.end(); nit++)
     {
        G.insert(nit->file1, nit->file2, nit->f);;
     }

     cout << endl << "The graph contains" << endl << endl;
     G.show();
     std::getchar();

these both have to work:

hi, give this a try:

getchar();
