Các hệ thống thủ tục từ xa đầu tiên có xu hướng được viết cho ngôn ngữ cấp thấp như C, và do đó đặt các byte trên mạng trông rất giống như các byte đã được bằng văn bản về bộ xử lý ngăn xếp mỗi khi một trong những C chức năng gọi là khác. Và cũng giống như một chương trình C có thể không an toàn | Taking Dev-C and Allegro for a Spin 45 purchased works exactly the same way that the free compiler does. Even more surprising is the fact that GCC is an optimizing compiler capable of compiling code with every bit as much efficiency and speed as Visual C or Borland C Builder. I think there is a false impression furthered by marketing forces that open-source software is inferior to commercial software and that proponents have simply gotten used to it. Although there is a small margin of truth in that the fact remains that Dev-C works just as well as Visual C for constructing Windows programs. What you will not find is a dialog editor a resource editor a toll-free customer support number or case-sensitive help depending on the IDE . Case-sensitive help is a very convenient feature if you are used to a commercial compiler package such as Visual C . Being able to hit F1 with the cursor over a key word to bring up syntax help is a difficult feature to do without. As an alternative I like to keep a C reference book handy such as C Programming Language Prentice Hall PTR 1988 by Brian Kernighan and Dennis Ritchie or C A Reference Manual Prentice Hall 2002 by Samuel Harbison and Guy Steele as well as an online Web site such as http c. I also keep the Allegro reference Web site open the site is located at http . allegro onlinedocs en. After you have programmed for a while without an online help feature your coding skill will improve dramatically. It is amazing how very little some programmers really know about their choice programming language because they rely so heavily upon case-sensitive help I don t suggest that you memorize the standard C and C libraries although that wouldn t hurt . This might sound ridiculous at first but it makes sense When you have to make a little extra effort to look up some information you are more likely to remember it and not need to look it up again. In addition open-source tools such as Dev-C are not .
