C++ Guessing game (is it as easy as it seems?)

Hi I am new to code and I want to advance on my basic skills. I have been able to do the simple program of the 'guess random number game' but I wanted to see if anyone was able to do this but with four numbers, so the computer would generate 4 random numbers and then the user would have to guess what all four are whilst the number of guesses is incremented. The user could also be told how many numbers they have correct so far. I have attempted it but haven't been able to succeed and this is the only platform I can really recieve any feedback on code.
