C++ Comparing user input to string array

I have a text file with first first names and last names in rows like this:

John Smith

Jaden Smith

Will Smith

Now I saved these files into a string array using a forloop to go till the end of file with "getline(inputfile, userName[i]); // Reads name"

Now I want the user to enter a name, I tried using "getline(cin, userInput);" and look through the array if that name is there.

The problem is although I'm entering a valid name, it never matches. So even though userName[0] is "John Smith" and userInput is entered as "John Smith", when I compare it, its never true via the comparison operator "=="

Example:

if(userName[0] == userInput) {

cout << "Match" << endl;

}
