C Constants, Variables and Data Types C is a structured programming language developed at AT&T’s Bell Laboratories of USA in 1972. It was designed and written by Dennis M. Ritchie. In the late seventies, C began to replace the more familiar languages of that time like PL/1, ALGOL etc. ...

HZ的教授讲的C language 4_2.1 Constants, Variables and Data types
变量其实只不过是程序可操作的存储区的名称。C 中每个变量都有特定的类型,类型决定了变量存储的大小和布局,该范围内的值都可以存储在内存中,运算符可应用于变量上。 变量的名称可以由字母、数字和下划线字符组成。它必须以字母或下划线开头。大写字母和小写字母是不同的,因为 C 是大小写敏感的。基于前一章讲解的基...
8.Struct(结构体):A user-defined data type that allows bundling together variables of different types under a single name.一种用户定义的数据类型,允许将不同类型的变量打包在一个名称下。 9.File Handling(文件处理):The process of reading from or writing to files. In C, file handling is commonly...
