The Evolution of a Programmer

High School/Jr.High
===================
10 PRINT "HELLO WORLD"
20 END

First year in College
=====================
program Hello(input, output)
begin
    writeln('Hello World')
end.

Senior year in College
======================
(defun hello
(print
(cons 'Hello (list 'World))))

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

    for(i = 0; i < 2; ++i)
        printf("%s", message);
    printf("\n";
}

Seasoned professional
=====================
#include
#include

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:perator=(const char *chrs)
{
    if (this != &chrs)
    {
        delete [] ptr;
        size = strlen(chrs);
        ptr = new char[size + 1];
        strcpy(ptr, chrs);
    }
    return(*this);
}

int main()
{
    string str;

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

    return(0);
