[英]how do i extract multiple substrings from a single string separated by space?
i was trying to solve this problem https://a2oj.com/p?ID=24 我正在尝试解决此问题https://a2oj.com/p?ID=24
my initial code (only testing the input part) 我的初始代码(仅测试输入部分)
#include<iostream>
using namespace std;
int main()
{
int t;
cin>>t;
while(t--)
{
int l;
string input;
cin>>l>>input;
string texts[l];
int c=0;
for(int i=0;i<input.size();i++)
{
if(input[i]==' ')
{c++;continue;}
else
{
texts[c]=texts[c]+input[i];
}
}
for(int i=0;i<l;i++)
cout<<texts[i]<<endl;
}
return 0;
}
its only scanning until it receives first ' '(space), and not other sub strings. 直到接收到第一个''(空格),而不接收其他子字符串为止。
You can use getline(); 您可以使用getline();
in this code i've used 't' as delimeter you can use space " " or whatever you want 在这段代码中,我使用了“ t”作为分隔符,您可以使用空格“”或任何您想要的
Example code 范例程式码
#include <iostream.h>
void main()
{
char line[100];
cout << " Type a line terminated by 't'" << endl;
cin.getline( line, 100, 't' );
cout << line;
}
