I am getting 2 errors when I run my c++ program. The first from IAP Test 2 which seems to be missing zeros on the first and the second line and a zero in the middle for the 5th line. The other error is from test  4 which seems to be missing a -1 on line 5 at the end. How can I fix these 2 errors?

I am getting 2 errors when I run my c++ program. The first from IAP Test 2 which seems to be missing zeros on the first and the second line and a zero in the middle for the 5th line. The other error is from test  4 which seems to be missing a -1 on line 5 at the end. How can I fix these 2 errors?

My code 

#include <iostream>

//defining constant integer 
const int CAPACITY=20;

//function prototype declaration

void fillArray(int array[],int& numElements);


bool removeElement(int array[],int& numberElements,int position);


//ToDo: Delcare a function that inserts the element in the given position
// insertElement - removes the element of the given index from the given array.

bool insertElement(int array[],int& numberElements,int position,int target);


//ToDo: Declare a funcxtion that searches for an element in the given array
// searchElement - searches for the element in the given array.
// @param int array[] is an unordered array of integers

int searchElement(int array[],int numberOfElements,int element);
