I am writing a program to get a multidimensional array from the user and than find out which of the elements in the array are larger than their "neighbors". Something just isn't working out though and I could use some help.

/*Constants*/
#define size 100
#define smallest -32766

int getRow(void);
int getColumn(void);
void getElements(int ne[size][size],int row,int column,int n1,int n2);
void initValues(int ne[size][size],int row, int column);
void showArray(int ne[size][size],int row,int column);
void showLargest(int ne[size][size],int row,int column,int n1,int n2);
bool checkArray(int ne[size][size],int row,int column,int n1,int n2);

/*Main Program*/
int main()
{

 column=getColumn();
 initValues(ne,row,column);
 getElements(ne,row,column,n1,n2);
 showArray(ne,row,column);
 if (checkArray(ne, row, column, n1, n2)==(true))
	 showLargest(ne,row,column, n1, n2);
 printf("\n");
}

{
