C语言程序设计中的若干疑难问题及其解决方法

详细介绍了C语言程序设计中容易遇到的几个疑难问题及其解决方法,并给出了示例。包括如何正确设置开发环境,缓冲区的数据要及时清理,输入结构体变量的float型成员的值可先赋给一个中间变量,给结构体指针变量赋值前应该先分配内存空间,代表空值的NULL的拼写形式不能随意改变。

Some Problems and Their Solutions in C Programming

Some problems and their solutions in C programming were discussed with in detail in this paper, and relevant examples were given. Including how to properly set up the development environment; the superfluous data which are left in buffer should be cleaned up by function fflush(stdin) or flushall() in time; the data for a float-type member variable of a struct-variable can't be got directly but via another float variable; the memory should be allocated before a struct-pointer get its value; and the spelling of NULL should not be any other formats.
