Hi im relatively new to programming and I am working on an encryption program. I know what I want to do but im a bit lost, youll understand when you see my code.

This is just the start of my code by the way

Code:
#include <iostream>
using namespace std;

int main()

{

    char unencrypted;
    char encrypted;

    cout <<  "Enter unencrypted English:"
            << endl;
    cin >> unencrypted;
Basically, there will be no algorithm. I want to state like a= f, b = z, c =q and I want each letter in the code the user has submitted to be translated. Any advice would be greatly appreciated.
