cpp from zero

I will guide you through Stage A and Stage B of the C++ Developer Chapter 1 curriculum. We will start by reviewing the lesson plan and then move to your first functional C++ program.

C++ Chapter 1: Lesson Plan and First Program

The curriculum is divided into five stages designed to move from theory to practice:

Your First Program (examples/first_program.cpp)

#include <iostream>

using namespace std;

int main() {
    // Section 1: what a computer program is
    cout << "First program, step 1" << endl;
    cout << "I can print text." << endl;

    return 0;
}

To compile and run this, I have executed the bin/cpp-from-zero first command:

Expected Output:

First program, step 1
I can print text.

Next steps

1. Modify the text inside the cout quotes and run bin/cpp-from-zero first again to see the change.
2. Remove a semicolon from one of the lines to see how g++ reports a compile error.
3. Type bin/cpp-from-zero calculator when you are ready to start the practice build.
