Question

write a program that simulates a lottery. the program should have an array of five integers named winningdigits, with a randomly generated number in the range 0-9 for each element in array. the program should ask the user to enter 5 digits and should store them in a second arrray named plaed. the program must compare the corresponding elements in the two arrays and count how many digits match, once the user has entered a set of numbers the program should display the winning digits and the players digits and tell how many digits match.

Explanation / Answer

please rate - thanks

you didn't say anything about whether to allow duplicate numbers of not, so I didn't

#include <iostream>

void results(int[],int[],int,int);
int main()
{srand(time(0));
int plaed[5],winningdigits[5],max=5;
int usercount=0,winningcount=0,i,matches=0;
   getLottoPicks(plaed,max);
   GenWinNums(winningdigits,max);
   matches=checkwins(plaed,winningdigits,max);
   results(plaed,winningdigits,max,matches);  
system("pause");
return 0;
}
void results(int a[],int b[],int n,int m)
