Arrays are Pointers | C++ For Java Devs Ep. 9

Join the Discord: https://discord.gg/4tHeAkxNg7

In this episode I talk about how pointers and arrays are similar. I begin by showing how everything in C++ is just a block of memory, arrays are blocks of memory, pointers are blocks of memory, and variables are blocks of memory. Then I show how you can use this knowledge to treat arrays as pointers and vice versa. Finally I show the danger of C++ by setting a separate variable unintentionally by accessing an out of bounds index in an array.
