We can use typedef to simplify the usage of function pointers. Imagine we have some functions, all having the same signature, that use their argument to print out something in different ways: #include<stdio.h> void print_to_n(int n) { for (int i = 1; i <= n; ++i) printf(...

URL patterns are written in urls.py file, each URL regex is given a function(Django view) from a views.py, so when a request is made, that function gets the call, with the HTTP request object, and then y...
Let's first recap how to initialize a 1D ruby array of integers: my_array = [1, 1, 2, 3, 5, 8, 13] Being a 2D array simply an array of arrays, you can initialize it like this: my_array = [ [1, 1, 2, 3, 5, 8, 13], [1, 4, 9, 16, 25, 36, 49, 64, 81], [2, 3, 5, 7, 11, 13, 17] ]
You can go a level further down and add a third layer of arrays. The rules don't change: my_array = [ [ [1, 1, 2, 3, 5, 8, 13], [1, 4, 9, 16, 25, 36, 49, 64, 81], [2, 3, 5, 7, 11, 13, 17] ], [ ['a', 'b', 'c', 'd', 'e'], ['z', 'y', 'x', 'w', 'v'] ], [ [] ...
Accessing the 3rd element of the first subarray: my_array[1][2]
Given a multidimensional array: my_array = [[1, 2], ['a', 'b']] the operation of flattening is to decompose all array children into the root array: my_array.flatten # [1, 2, 'a', 'b']
