因为getline函数返回时丢弃换行符,换行符将不会存储在string对象中。 Prototype: ssize_t getline (char **lineptr, size_t *n, FILE *stream) Description: This function reads an entire line from stream, storing the text (including the newline and a terminating null character) in a buffer and stor...

第二个 char space时，没有给space赋值，然后计算机就给他随机赋了一个值，比如我的gcc就给space赋了一个 'u'值，你的就给space赋了一个'2'值。所谓ascii，是一种编码格式，就是用一个 7 ’位' 二进制编码 表示一个字符，所以一共可以表示 表示范围为0到2^-1=255共256个字符，例如大写字母...
