Why use a high-level language? Speed of development of software may be one reason. Software development is often on the critical path for a product. The time to get a product in the market-place can be vital, and using a high-level language can reduce software development time by 50％．This saving is mainly obtained because the programmer does not have to translate a high form of the program, what-ever that form may be, into a very low level．The compiler performs the last stage of transformation. Further saving may be obtained if the high-level language can be easily mapped from some higher-level representation。
  
　　Another reason for using a high-level language’s to reduce maintenance costs ,and in general, the cost of rework．Furthermore the legibility and ease of understanding of the program are much greater than in assembly language. The program is more likely tube correct in the first place, besides being easier to amend. With microcomputer products being sold in thousands, the cost of dealing with mistakes after the product reaches the consumer can be enormous    A further reason for using a high-level language’s for reliability and safety. These properties are as scouted with correctness. The reader of a program is much more likely to detect wrong functionality if the program has been written in a high-level language rather than in a lower-level one．
   
　　With high-level languages there is a chance of：Opting with the increased complexity, of managing; he software development, of keeping the staff, of achieving target dates and of avoiding disaster.

为什么使用高级语言      

　　为什么使用高级语言？软件方展的速度是一个原因。对一个产品来说，软件的发展，常常是沿着关键途径进行的（常常是其关键所在 ）。在市场上推出一种产品的时间是至关重要的，利用高级语言可以减少软件开发时问的50%.这种节约的获得主要是因为程序员不必将程序（小论其为何种形式）的高级形式翻一泽成非常低级的形式。变换的最后阶段是由编泽程序执行的。如果高级语言可以容易地从某种高级表达式来映射的话，那么还可以 获得进一步的节约。
    
　　采用高级语言的另一原因，是为了减少维护费用，并且，一般地说，可以减少返工的费用。此外，程序的清晰度及易理解性也比汇编语言高。除了更易于修改之外，程序易编写得正确。随着微型计算机产品数以千计地销售在这些产品到达顾客之后．处理的费用将是巨大的采用高级语言的进一步原因是为了可靠性及安全性。这些特征是与正确性相联系的。如果此程序是用高级语盲一编写而不是低级语言编写的话，程序的读者能够较容易地发现错误的功能。
    
　　使用高级语言可以提供以下机会，对软件日益增加的复杂性的处理，软件开发的管理，人员培养，目标日期的确保以及避免灾难。
