пошло поехало, - сейчас все сюда будут код постить

#include <iostream.h>
int a;
void main()
{
cin>>"сейчас все сюда будут код постить";
cout<<"\nА одно другому не мешает\n";
cin>>a;

Mx
cin>>"сейчас все сюда будут код постить";
а cin'ить в статическую переменную нельзя

Блин. Обшибся. Дебаггеров на меня нет.

31-08-2003 09:50
Mad fancier
#include <iostream.h>
char a;
void main()
{
cin>>a;
If (a=="а cin'ить в статическую переменную нельзя")
{
cout<<"\nА так?\n";
}
}

Чебурашка-ниндзя
Mx уже лучше!

...только в стандарте функция main() должна возвращять int значение и заканчиватся строкой return 0;, но это так - мелочи

В стандарте main() ничего может и не возвращать, на то она и void бывает.
Да и как в байт вы целую строку запихнули?;)

AP_
Да и как в байт вы целую строку запихнули
Как как. Кавычками. Кавычки автоматом массив создают. Кажется . Вобщем сто лет я уже не програмил. Пойду Javу учить.
