Declaring and Initializing Variables
There are surprisingly many details to declaring and initializing variables! Doing these things well prevents bugs that can be really hard to find. This video explores those details with examples from a number of languages with the goal of giving you the big picture of things to worry about. #programming #declaringvariables

ABOUT MY CHANNEL
My channel is about good software engineering practices. We cover introductions to programming in C and Java. But I also have lots of software and computer engineering topics like PIC programming, advanced programming techniques, and things that distinguish good code from code that works.
