Indeed there is, im not thinking straight as im falling asleep but anyway you could use something like this.

 C++ Syntax (Toggle Plain Text) 
#include <cctype>
#include <iostream>
#include <string>
using namespace std;
 
string stripcase(string instring){
     string buffer = "";
     for(int i = 0; i < instring.length(); i++){
          buffer += tolower(instring[i]);
     }
     return buffer;
}
 
int main()
{
     string input1 = "winSton Chruchill"; //this would be set via user input of course, just an example
 
     string correct1 [2] = {"Winston Churchill", "Chruchill"};
 
     for(int i = 0; i < 2; i++)
     {
          if(stripcase(correct1[i]) == stripcase(input1)){
               cout << "Congratulations, you got it!";     
          }
      }
 
     return 0;
)
#include <cctype>
#include <iostream>
#include <string>
using namespace std;

string stripcase(string instring){
     string buffer = "";
     for(int i = 0; i < instring.length(); i++){
          buffer += tolower(instring[i]);
     }
     return buffer;
}

int main()
{
     string input1 = "winSton Chruchill"; //this would be set via user input of course, just an example

     string correct1 [2] = {"Winston Churchill", "Chruchill"};
    
     for(int i = 0; i < 2; i++)
     {
          if(stripcase(correct1[i]) == stripcase(input1)){
               cout << "Congratulations, you got it!";     
          }
      }

     return 0;
)

Something like that is what your after, there are probably better ways but i cannot thing straight right now, im gonna shoot off anyway so if you need it explaining then im sure one of the other guys will help. If not i will when im next online.

I recomment reading up on cctype as this will help you understand what is going on, also you should be aware that you are able to treat strings as char arrays, these will help you understand this.

buffer += tolower(instring[i]);
buffer += tolower(instring[i]);

I have been messing around some more with the for statement i have a question that has 5 possible answers and do this statement

 c++ Syntax (Toggle Plain Text) 
      cout << "question?\n";
      getline(cin,answer1);
      for (int i=0; i  <  5 ; i++){
	if (correct[i]==answer1)
	  cout << "do something!!\n\n";};
	else{
	  cout << "do something!!\n\n";
	  break;};
      cout << "question?\n";
      getline(cin,answer1);
      for (int i=0; i  <  5 ; i++){
	if (correct[i]==answer1)
	  cout << "do something!!\n\n";};
	else{
	  cout << "do something!!\n\n";
	  break;};

then i compile it with g++ and it brings up with error
k.cpp: In function ‘int main()’:
k.cpp:19: error: expected primary-expression before ‘else’
k.cpp:19: error: expected `;' before ‘else’

i cant figure out where to put or take away the ; ??

cout << "question?\n";
      getline(cin,answer1);
      for (int i=0; i  <  5 ; i++){
	if (correct[i]==answer1)
	  cout << "do something!!\n\n";	
                else{	  
                       cout << "do something!!\n\n";
                 }
}
cout << "question?\n";
      getline(cin,answer1);
      for (int i=0; i  <  5 ; i++){
	if (correct[i]==answer1)
	  cout << "do something!!\n\n";	
                else{	  
                       cout << "do something!!\n\n";
                 }
}

it was just down to bracket placement, i think this will work im sort of busy at the same time so if theres a mistake just let me know. you had placed the else statement outside of the for loop.
