Lottery C++ Help

Vandalism (183)
.) Lotto is a game in which winners are chosen by random drawing of numbers from among those who have paid money to participate. Write a program that will simulate the lotto game by asking the user five numbers(use array) and should generate a random number in the range of 0-9 for each array element. The program will compare the corresponding elements in the two arrays and if a count of the digits that matches. For instance, if the lottery array contains 8,5,0,2, and 4 and the user array contains 5,3,0,8 and 4, we can say that there are three numbers that matches. The program should display the random numbers stored in the lotto array and the matching digits. If all of the digits matched, display a message proclaiming the user as a grand prize winner. Prizes are as follows:
5 matching digits- 500,000 pesos
4 matching digits-100,000 pesos
3 matching digits- 20,000 pesos
2 matching digits- 500 pesos
1 matching digits-10 pesos or Balik taya! ~(>3>)~
0 matching digits-Try Again!~(^3>)~

I use this code:

ok i figured out everything i just need to know how to get the prize?
mutexe (2372)
you seem to be doing a hell of a lot of the same thing e.g.
MN = MN + 1;

(which is MN+=1, or MN++).

If you used a for loop and iterated over the array your code would shrink down a hell of a lot.

I haven't checked exactly what indices from which arrays you are comparing, but it's this kind of idea. I think :)

i fixed it and the only problem is the prize
cire (8284)
= is assignment. == is comparison.
Vandalism (183)
did that but still the prize does not output :(
cire (8284)
In:

1
2
3
4
5
6
 
    if ( WN[i] == UI[j] )
        cout << WN[i] ;

    {
        MN++ ;
    }


line 5 is not governed by the if condition. It is executed unconditionally, so MN will always be 25 after your nested loops. It would have been easier to spot if you'd bothered researching how to use code tags on this site. ;)
