Question

c++中如何将输入的字符串(不知长度)存入数组中?

Answer 1

#include<iostream>
#include<string>
#include<windows.h>
using namespace std;
int main()
{
string str;
char temp;
cout<<"输入字符串,按回车键结束输入"<<endl;
while((temp=cin.get())!='\n')
{
str +=temp;
}
const int LEN =str.length();
char* dest = new char[LEN];//根据输入字符串的长度，创建字符数组
for(int i = 0;i<LEN;i++) //将字符串保存到字符数组中
{
dest[i]=str[i];
cout<<dest[i];
}
delete dest;
system("pause");
return 0;
}
