highlighter- Java 1== sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long) <= sizeof(longlong) 由于历史原因,整型的位宽有多种标准: 为解决这一问题,C99/C++11引入了定宽整数类型。 定宽整数类型 定宽整数类型本质上是普通整数类型的类型别名。 <cstdint>提供了若干定宽整数的类型和各...

在sort和unique函数中就默认使用了less 和equal_to函数, 上面的一段代码,其实使用了string的以下功能: 存储功能,在getline() 函数中 查找功能,在find() 函数中 子串功能,在substr() 函数中 string operator < , 默认在sort() 函数中调用 string operator == , 默认在unique() 函数中调用 总之,有了string 后...
