Cpp 中的 struct 不同于 C 中的 struct,cpp 的 struct 被扩展为类似 class 的类说明符。 结构体是一系列成员元素的组合体,允许存储不同类型的数据项,成员变量可以是各种数据类型,包括整数、浮点数、字符串、其他结构体等,所以你可以根据需要定义自己的结构体来组织数据。 定义结构体 cpp structMyStruct{//定义...
很简单,写一个小小的循环,遍历一次就好了。 于是乎,通过两重的for循环,从-256循环到255,利用printf("%c%c",s[0],s[1]);便简单的获得了整个字表。 但是这样获得的字表还有很多的非汉字字符,通过简单地肉眼找规律,我们很容易发现汉字(不一定是中文,但是都是汉文化圈的文字)在字表中分布于 (first >= -...
