C語言的開發模式, 是編寫.c的Source Code, 再經由Compiler編譯成Object Code。所謂Object Code指的是和硬體相關的機器指令, 也就是說當我們想要把C程式移植到不同的硬體時, 必須要重新Compile,以產生新的執行檔。除了需要重新編譯外,新系統是否具備應用程式所需的程式庫,include的檔案是否相容, 也是程式能否在新機器上順利編譯和執行的條件之一。-C language development model, are prepared. C of the Source Code, and then the compiler Compiler into Object Code. The so-called referring to the Object Code and hardware related to machine instructions, that is to say when we want to put C code ported to different hardware, we must re-Compile, in order to generate a new executable file. In addition to the need to recompile, the new system is required with application libraries, include files are compatible, but also whether the program on new machines at the smooth implementation of the compiler and one of the conditions.
