Quick sort is a very commonly used sorting algorithm. A quick sort demo algorithm coded $($QuickSort$.$cpp$)$ in C$++$ can be found under Sorting chapter. In that code, we sort items of int array.

Your task in this assignment is to sort structs in array. The struct isCreate an array with $500$ points, which are randomly initiated with x between $0$ and $30$ and y between $0$ and $60.$ Then modify the Quick Sort algorithm $($QuickSort$.$cpp$)$ to sort points. Comparison of the points should be carried on first x$,$ then y$.$ It means that if two points has same x values, then you should compare y values of them.
