Hi, this is my first time posting and I would like thank everyone in advance. I'm doing a homework assignment that requires me to design a teller application which simulates a bank. I'm currently getting a segment fault, after I call one of my getBranch(). I've tried to do this the other way by returning a Branch* and the same error was returned. Here is my main():
#include <string>
#include <iostream>
#include <fstream>
#include <stdio.h>
#include <vector>
#include "Branch.h"
#include <sstream>

using namespace std;
//Branch* getBranch(string branchName);
void getBranch(string branchName, Branch *currBranch);
void writeBranch(Branch *branch);

}I've ran into similar problems before due to shallow copy, but shouldn't using a pointer solve the problem?
