The Evolution of a Sepples Programmer

Learned basic C++ from an inadequate tutorial.

#include <iostream.h>
using namespace std; // thanks, joe
void main(int argc, char** argv) {
    cout << "Hello, world!" << endl;
}

Learned basic C++ from a slightly better tutorial.

#include <iostream>
using namespace std;
int main(int argc, char* argv[]) {
    cout << "Hello, world!" << endl;
    return 0;
}

Learned about namespace pollution.

#include <iostream>
int main(int argc, char* argv[]) {
    std::cout << "Hello, world!" << std::endl;
    return 0;
}

Learned about classes.

#include <iostream>
#include <string.h>
class Hello {
private:
    char* msg;
public:
    Hello() {
        this->msg = strdup("Hello, world!");
    }
    ~Hello() {
        delete this->msg;
    }
    char* hello() {
        return this->msg;
    }
};
int main(int argc, char* argv[]) {
    Hello* hello = new Hello();
    std::cout << hello->hello() << std::endl;
    delete hello;
    return 0;
}

Learned about the C++ string container.

#include <iostream>
#include <string>
class Hello {
private:
    std::string msg;
public:
    Hello() {
        this->msg = "Hello, world!";
    }
    std::string hello() {
        return this->msg;
    }
};
int main(int argc, char* argv[]) {
    Hello hello;
    std::cout << hello.hello() << std::endl;
    return 0;
}

Found out about the STL.

Mastered the basic containers of the STL.

#include <iostream>
#include <string>
#include <vector>
int main(int argc, char* argv[]) {
    std::string hello = "Hello, world!";
    std::vector<char> v;
    for (unsigned int j = 0; j < hello.length(); ++j) {
        v.push_back(hello[j]);
    }
    std::vector<char>::iterator i;
    for (i = v.begin(); i != v.end(); ++i) {
        std::cout << *i;
    }
    std::cout << std::endl;
    return 0;
}

Mastered the STL.

#include <iostream>
#include <string>
#include <algorithm>
class printc { public: void operator() (char c) { std::cout << c; } };
int main(int argc, char* argv[]) {
    std::string hello = "Hello, world!";
    std::for_each(hello.begin(), hello.end(), printc());
    std::cout << std::endl;
    return 0;
}

Read the C++ FAQ Lite and realized C++ mastery is impossible.

#include <iostream>
int main(int argc, char* argv[]) {
    std::cout << "Hello, world!" << std::endl;
    return 0;
}

Read the C++ FQA Lite.

#include <stdio.h>
int main(int argc, char* argv[]) {
    printf("Hello, world!\n");
    return 0;
}

Heard of 4chan and wound up in /b/.

HAI
CAN HAS STDIO?
VISIBLE "HAI WORLD!"
KTHXBYE

Found a replacement for /b/ after finding it overrun by ``cancer'' and ``newfags.''

One word, the forced indentation of code.  Thread over.  Also, read SICP!

Read SICP after months of telling people to read SICP.

(display "Hello, world!")
(newline)

Achieved Satori after re-reading SICP every day for many years.

void main() { puts("Hello, world!"); }

And so, Christopher wins again.

Also, Xarn, you sound like someone I know. He claims to be all cool and free and GNU, and that programming is done mostly for fun and not profit, but he secretly is entrepreneurs' bitch and does all the Java and PHP work for them.
