scanf Format SpecifiersJump to: navigation, search Go Up to scanf, wscanf In scanf format strings, format specifiers have the following form: % [*] [width] [F|N] [h|l|L] type_char Each format specifier begins with the percent character (%). ...
(1) 当 scanf 中的输入格式说明符 (Format specifiers) 不是 "%c"的时候,那么空白字符 (whitespace) 将起到分隔符的作用。把分隔好的两个数据分别赋值到各自定义好的变量或数组中去,两个数据之间的 whitespace 被从缓冲区读出但是不起任何作用,当然最后一个 '/n' 会被留在缓冲区内,除非用 getchar(); 或...

2)使用%[specifiers]格式控制字符的读取,例如: char str[20]; scanf(%[A-Z] str); //读取大写字母 3)使用格式控制字符读取的最大数量,例如: char str[20]; scanf(%5s str); //最多读取5个字符 4)使用scanf函数进行数据输入: int num; scanf(%d &num); 5)使用%c来读取字符: char ch; scanf(%...
