摘要
通过信号与系统中的部分典型实例，设计了在西文ＤＯＳ下用Ｃ语言实现中文界面提示的应用程序。由于该程序实用性强且生成的界面操作简单，可以脱离Ｃ语言环境，在ＤＯＳ下直接运行，并具有占用内存少和运行速度快等优点。
Using some typical examples of the signal and system,the application program for Chinese intertace prompt under the English DOS environment is developed with C language.The program can be run independent of the C environment.Its main advantages are high speed running and less memory requirement.
