在指针当中的类型中我们知道有一种指针类型为字符串指针char*;可以通过两种方法来访问一个字符或者是字符串。 1、第一种就是使用字符数组来存放字符串或者字符来实现操作。 2、下面所介绍的就是使用字符指针指向一个字符串,此时可不能定义数组。 一般的使用方法如下👇 代码语言:javascript 代码运行次数:0 运行 AI...

string继承自basic_string,其实是对char*进行了封装,封装的string包含了char*数组,容量,长度等等属性。 string可以进行动态扩展,在每次扩展的时候另外申请一块原空间大小两倍的空间(2*n),然后将原字符串拷贝过去,并加上新增的内容。 (49)一个函数或者可执行文件的生成过程或者编译过程是怎样的 预处理,编译,汇编,链...
