Search Engine Looping

I am writing a search engine. When you search something, the results come up, with another search box. Is there any way I can do that? Here is my code so far:

Code:

#include <string>
#include <iostream>
#include <cctype>
#include <algorithm>

using namespace std;

int main()
{
 string str1;
 cout << "HIDDEN";
 cin >> str1;
 cout << "\n";
 transform(str1.begin(),str1.end(), str1.begin(), tolower);
 // Results
  if(str1 == "hidden1")
  {
  str1 = " ";
  cout << "hidden results";
  cout << "Search: ";
  cin  >> str1;
  }
else if(str1 == "hidden2") cout << "hidden results 2";
else if(str1 == "hidden3") cout << "hidden results 3";
else cout << "No files found";
return 0;
}

In this code, the search box in the results doesn't work correctly!

Ummm.what? Search box? C++ has no concept of serach boxes.
Please try to explain what on earth you are talking abot.

Use WinAPI and create another window?

Okay, I'm gonna close this, but what I was trying to do was create a search engine in C++ for DOS. I had everything right all along, but I had the transform function in the wrong place. I figured it out on my own. Thx, though!
