事实上，这样也未尝不可。只不过现在 destination 变成了 char*，而且是作为指向源字符数组的指针存在。下一个字符串操作是 strlen，它的作用是获取字符串的大小，但不包括空终止符。#include<stdio.h>#include<string.h>intmain(){char str[] = "Hello, world!"; // The string to find the length ofint...
string(int n,char c); //用n个字符c初始化 此外,string类还支持默认构造函数和复制构造函数,如string s1;string s2="hello";都是正确的写法。当构造的string太长而无法表达时会抛出length_error异常 string类的字符操作: const char &operator[](int n)const; ...

int len,char c);//把字符串当前大小置为len,并用字符c填充不足的部分 例如: #include <iostream> #include<string> using namespace std; int main() { string s = "Student"; string s1; cout <<"s1的容量为:"<<s1.capacity()<< endl; ...
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...
