文件读写方式

常见C语言的文件读写方式

fopen("*.*","r")

fopen("*.*","r+")

fopen("*.*","rb")

fopen("*.*","rb+")

fopen("*.*","w")

fopen("*.*","w+")

fopen("*.*","wb")

fopen("*.*","wb+")

fopen("*.*","a")

fopen("*.*","a+")

fopen("*.*","ab")

fopen("*.*","ab+")

注释：逗号右边的引号里r表示只读,w只写（会覆盖原内容，如果以前已经存过该文件），a追加，带b的表示以二进制形式读（写），带+的表示可读可写，比如r为只读，r+就是读写。
