HELP Exiting a Function after an if statement!

[atiq]

I want the function to exit (NOT continue) if the encryptedMess.t xt 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.
