演習の環境

 

How to use cygwin

便利な命令:

フォルダの作成: mkdir newfolder (例: mkdir CP2017)

フォルダへの移動: cd CP2017
(フォルダ名とフォルダ名の間は \ のではなく /)

Windows のフォルダへの移動 (C: ドライブの場合): cd /cygdrive/c

現在のフォルダの場所の表示: pwd

現在のフォルダの内容の表示: ls (又は dir)

 

A Simple C Program

(the most famous C program)

#include <stdio.h>

int main (void)
{
    printf ("Hello World!\n");

    return 0;
}

 

Program Compilation and Execution

To avoid overwriting a.exe:

 

Edit - Compile - Go

Programming is mostly a repetition of the following three activities:

  1. Edit: Write or fix the program
  2. Compile: Compile the program from a human-readable form to a form that the computer can execute
  3. Go: (Try to) execute the program

[For interpreted programming languages (e.g. Ruby), steps 2 and 3 are combined.]

 

Installing cygwin and gcc

(detailled explanation with pictures)
(for Windows; ask for instructions if you use a Mac)
