Sample format is:
The quick brown fox jumps over the lazy dog.
question = to ? be : !be;
The quick brown fox jumps over the lazy dog.
question = to ? be : !be;


In fact,i got result below:
The quick brown fox jumps over the lazy dog.
The quick brown fox jumps over the lazy dog.
question = to ? be : !be;
question = to ? be : !be;

AND the program was accepted, do you have the same doubt with me?Some one can help me figure this out?

#include <iostream>

using namespace std;
int main()
{
for(char c;c!=EOF;)    
{
   if((c=cin.get())!='\n')
      cout.put(c);
   else
      cout<<endl;
}
    
}
说我运行超过时间了，唉。。。
