#include <string> 


using namespace std; 
char caesar( char ); 
int main() 

{ 
    string input; 

    do { 
        cout << "Type the message you want to code and then press enter" << endl; 
        cout << "Press enter again if you want to quit because you are boring" << endl; 
        getline(cin, input); 
        string output = ""; 
        for(int x = 0; x < input.length(); x++) 
        { 
            output += caesar(input[x]); 
        } 

        cout << output << endl; 

    } while (!input.length() == 0); 

}   
char caesar( char c ) 
{ 
    if( isalpha(c) ) 

    { 
        c = toupper(c); 
        c = (((c-65)+13) % 26) + 65; 
    } 

    return c;
}

Have you saved the cpp file before compiling? If yes, which line does the compiler print the error to?
