    using arrays

    hi everyone, i need some help with my assignment for the week. we're supposed to (taken directly from assignment page) "write a program that inputs an array of 10 integers from the user, and removes the duplicate array elements."

    the only error i get when i compile is: line 49, error #2169: expected a declaration. i know there's more than likely other errors. a tutor was helping me out. here is my coding:

    Code:
    
    #include<iostream>
    
    #include<iomanip>
    
    using namespace std;
    
    
    
    int main()
    
    {
    
      const int length = 11;    // holds variable for length
    
      int dedup[length];        // holds variables for length and array
    
      int array[10];
    
    
    
    cout << "Please enter 10 integers, hitting return after each one: "; 
    
    int i = 0;
    
    int i2 = 0;
    
    int i3 = 0;
    
    
    
    for(i=0; i < 10; i++)    // loop for user input of numbers
    
    
    
    cin >> array[i];
    
    
    
    for (i2 = 0; i2 < 10; i++) // i'm not sure what this line is for, a tutor was helping me but had to leave. 
    
    {
    
      if(array[i] == 0)
    
      array [i] = 200;
    
      if(array [i] == dedup[i2])
    
      {
    
        break;
    
      }
    
      else if(i == 9)
    
      {
    
        dedup[i3] = array[i];
    
        i3++;
    
      }
    
    }
    
     
    
      return 0;
    
    }
    
    
    
    // Function to find duplicates
    
    void output(int dedup[], int i3);
    
    {
    
      int count = 0;
    
      cout << "You entered" << i3 << "distinct numbers.";
    
    
    
      for (; count < i3; count++)
    
      {
    
        if(dedup[count] == 200)
    
        {
    
          dedup[count] = 0;
    
        }
    
        cout << dedup[count] <<" ";
    
        cout << endl;
    
      }
    
    }
    this is my last assignment for the semester and i'm desperate to finish it asap, i have other finals to study for. any help is extremely appreciated. thank you!

    // Function to find duplicates

    void output(int dedup[], int i3);
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Why use a number within a variable name? It can be quite confusing and I think it's bad practice. It is up to you though!
