pls help me with this one..everything is ok but when i add student and faculty number and then try to list them says "No added students'...:@
This is:
main.cpp
#include <iostream>
#include "Student.h"
#include "Course.h"

//find course
for (list<CCourse*>::iterator i = courses.begin(); i != courses.end(); i++)
{
if ((*i)->GetName().compare(name) == 0)
{
course = *i;
}
}
return course;
}
CStudent* findStudent(string fn)
{
CStudent* student = NULL;
//find student
for (list<CStudent*>::iterator i = students.begin(); i != students.end(); i++)
{
if ((*i)->GetFN().compare(fn) == 0)
{
student = *i;
}
}
return student;
}
