Removing duplicates from an array

[DocCeaser]

The removeAll function is where my problem is. Every time I compile it I get an error saying
[Linker error] undefined reference to `removeAll(int*, int, int)'
ld returned 1 exit status
The goal of this program is to remove all of the duplicates from the array.

#include <iostream>
#include <fstream>

using namespace std;
const int MAX_SIZE=25;
ifstream infile;

void initialize(int numbers[], int length);
void print(int numbers[], int length);
void removeAll(int numbers[], int length, int num2remove);

int main()
{
    int numbers[MAX_SIZE], length=0, num2remove;
    
    initialize(numbers, length);
    print(numbers, length);
    cout<<"Enter a number to remove"<<endl;
    cin>>num2remove;
    removeAll(numbers, length, num2remove);
    print(numbers, length);
 
  system("PAUSE");
  return 0;
}
void initialize(int numbers[], int length)
{
     infile.open("pr5.txt");
     for(int i=0; i<MAX_SIZE; i++)
     {
     infile>>numbers[i];
     length++;    
 }
}
void print(int numbers[], int length)
{
     for(int i=0; i<MAX_SIZE; i++)
     cout<<numbers[i]<<endl;
     
}
void removeALL(int numbers[], int length, int num2remove)
{
        for(int i=0; i<MAX_SIZE; i++)
        {
         if(numbers[i] == num2remove)
            length-1; 
			for(int i=0;i<MAX_SIZE;i++) 
				numbers[i]=numbers[i+1];
			
		
		}

}

In main() you use removeAll and you define removeALL (with capital L)

Function (and variable) names are case sensitive. The removeALL function does not match the intended capitalization in the declaration.
