14 Ступеней эволюции программистов



Ступень 1: Школьник

10 PRINT "HELLO WORLD"
20 END


Ступень 2: Первокурсник

program Hello(input, output)
begin
writeln('Hello World')
end.

Ступень 3: четвёртый курс института

(defun hello
(print
(cons 'Hello (list 'World))))

Ступень 4: Первый раз на работе в ВЦ

#include <stdio.h>

void main(void)
{
char *message[] = {"Hello ", "World"};
int i;

for(i = 0; i < 2; ++i)
printf("%s", message[i]);

printf("\n");
}

Ступень 5: Бывалый программер

#include
#include <string.h>

class string
{
private:
int size;
char *ptr;
public:
string() : size(0), ptr(new char('\0')) {};

string(const string &s) : size(s.size)
{
ptr = new char[size + 1];
strcpy(ptr, s.ptr);
};

string()
{
delete [] ptr;
};

friend ostream& operator <<(ostream &, const string &);

string& operator=(const char *);

ostream &operator<<(ostream &stream, const string &s)
{
return(stream << s.ptr);
};
};

string& string::operator=(const char *chrs)
{
if (this != &chrs)
{
delete[] ptr;
size = strlen(chrs);

ptr = new char[size + 1];
strcpy(ptr, chrs);
}

return *this;
}

int main(void)
{
string str;

str = "Hello World";
cout << str << endl;

return 0;
}
