my wanted results

 generating...
 gen 1284
 generating...
 gen 3507
 generating... 
 gen 1490
 generating...
 gen 1519
 generating...
 gen 2546
 Write your guess (only 1-6, no ENTER is needed) [20 guesses left]
 2465
 num1 5
 num2 6
 num3 4
 num4 2
 you got  0 HITS  4 MISSES
 Write your guess (only 1-6, no ENTER is needed) [19 guesses left]

And the real result is:

 generating...
 gen 1284
 generating...
 gen 3507
 generating...
 gen 1490
 generating...
 gen 1519
 generating...
 gen 2546
 Write your guess (only 1-6, no ENTER is needed) [20 guesses left]
 2465
 num1 5
 num2 6
 num3 4
 num4 2
 you got  0 HITS  0 MISSES // it should be 0 HITS 4 MISSES
 Write your guess (only 1-6, no ENTER is needed) [19 guesses left]

Answer 1

Definition for variable round is nowhere in sight. It should be initialized to the maximum number of tries before the loop where you get user input.

When you read user input, you should store that into variables inum1, inum2... not num1, num2 etc.

Furthermore, you mix calls to getch() and calls to getchar(). I'm not sure if the behavior is what you expect.

Note that we had to reformat your code to make sense of it. Learn to format your code properly. Avoid long lines, indent consistently, using spaces, not tabs.
