Sorting a 2D-Array into Ascending order - c

Question

I am trying to print out the contents of an Array into Ascending order, i am also using Functions (part of a task i have been assigned) - i am fairly new to C/C++ hence if anything is a mess.
The Sorting algorithm i have used just outputs all the numbers into a random order, any way to resolve or correct this? - Ideally this needs to output into the 2x2 grid as the Array Displays.
Ascending Order Output
include <stdio.h>/*Seperate Function for Input ArrayInt */
int main(){
int arrayHeight, array[100][2], xCoord, yCoord, i;
printf ("***** Bubble Sort ***** \n");
printf("\n How many items of data do you wish to enter? ");
scanf("%d",&arrayHeight);
for(i=0; i<arrayHeight; i++){
printf("Please enter in the X coordinate: ");
scanf("%d", &xCoord);
printf("Please enter in the Y coordinate: ");
scanf("%d", &yCoord);
array[i][0] = xCoord;
array[i][1] = yCoord;
}
DisplayArray(array, arrayHeight);
BubbleSort(array, arrayHeight);
}
int DisplayArray(int array[100][2],int arrayHeight, int swap) {
/*Displaying Array elements*/
int i, j;
printf("\n The 2-D Array contains : \n");
for(i=0; i<arrayHeight; i++)
{
printf("[%d][%d]\n\r", array[i][1], array[i][0]);
}
}
int BubbleSort(int array[100][2], int arrayHeight)
{
/*Sorts the Array elements into appropriate chosen sorting order - Ascending*/
int swap, i, j, k;
for(k =0; k< arrayHeight; k++) {
for (i = 0; i <arrayHeight; i++) {
for (j = i+1; j < 3; ++j) {
if (array[i][0] > array[i][-1]) {
array[i][1] = swap;
swap = array[i][0]; /*Array = Array Name*/
}
}
}
}
printf("\n Printing in Asending Order: ");
{
for (i=0; i<arrayHeight; i++)
{
for (j=0; j<arrayHeight; j++)
{
printf("\n [%d][%d] ", array[i][-1], array[i][1]);
}
}
}
