Question

C++怎样把整行读入字符串数组中？

比如输入abc abca abcab abcb a，将它存到一个字符串数组里，用什么方式读入呢？cin.getline吗？具体怎样用呀，大虾教教我，3Q
空格也不能忽略

Answer 1

#include <iostream>
#include <string>
using namespace std;
int main()
{
string str;
char *a;
getline(cin,str);//读取一行保存至str
a=new char[str.size()+1];//给A分配str长度+1，+1是为了保存\0
for(string::size_type s_index=0;s_index!=str.size();s_index++)
a[s_index]=str[s_index];
a[str.size()+1]='\0';
cout<<a;
system("pause");
return 0;

}

Answer 2

#include <iostream.h>

void main ()
{
char ch[100];
cin.getline(ch,100);
cout<<ch<<endl; //输出字符串
}

Answer 3

char array[STR_NUM][STR_LENGTH];
... ...

char * p[STR_NUM] = array;
while(scanf("%s",p++));

读取完毕！ ^_^

Answer 4

#include <iostream>
#include <string>
using namespace std;
