HELP Exiting a Function after an if statement!

[atiq]

I want the function to exit (NOT continue) if the encryptedMess.txt file does not exist!

Below is the code for this function and it is after line 15 where i need help:

//Process of Decyption
 
void Decrypt()
{
    char decrypted;
    stringLoc =0;
 
        char ch;
 
 
        ifstream encryptedMess("encryptedMess.txt");        //Open Encrypted File message
 
        if (!encryptedMess)
        {
            cout<<"Error opening the file"<<endl;
 
 
        }
        while (!encryptedMess.eof())
        {
            encryptedMess.get(ch);
            decrypted = ch-difference;
 
            cout<<decrypted;
        }
        encryptedMess.close();
        cout<<endl<<endl;
 
//Save to text File
        ofstream decryptedMess;
        decryptedMess.open("decryptedMess.txt", ios::out);
        decryptedMess<<decrypted;
        decryptedMess.close();
}

Any help would be much appreciate!

Thanks

Look up the return statement in any basic book on the language (or on the web)

Thank you for your reply!

i cant use a return statement because it is a void function. What alternative way can i achieve this? I would be grateful if you could provide the coding.

Thanks

Yes you can, I repeat, look up the return statement in any basic book on the language.
