Проблема с классами c++
20.09.2011, 19:48. Показов 561. Ответов 0
Здравствуйте! Помогите, пожалуйста, сделать следующее.
1. В проге нужно перенести часть кода из основной программы в метод класса.

| if(m>x1[i].GetCost())
{
cout << " " << x1[i].GetName() << " "
<< x1[i].GetNumber() << " "
<< x1[i].GetCost() << " " << endl;
t++;
} |
|
Этот код нужно организовать в методе. В основной программе сделать что-то вроде x1[i]->Poisk(m).
2. Нужно сделать "ввод с клавиатуры с помощью класса без параметров". Как-то так)
Заранее огромное спасибо!
