    I don't know how data.1 is a variable name, as '1' is not an acceptable variable declaration, nor is anything with a '.' in it.

    A variable is something that holds data.
    Put what you want into the variable.

    Code:
    #include <iostream>	
    #include <fstream>
    
    
    using namespace std;
    
    int main()
    {
    
    	ofstream out;
    
    	char file_name[16];
    	cout << "Enter the name of the file (including ext, IE test.txt: ";
    	cin >> file_name;
    
    	out.open(file_name);
    
    	out << "See, like this.";
    
    	out.close();
    
    	return 0;
    
    }
