Although their encryption method was basic compared to today’s standards, decrypting an intercepted message was a very time-consuming task for the Allies.īy the time the encryption was broken, the messages were obsolete. How Did Programming Begin?īack during World War II, Nazi Germany had been using a machine called Enigma to encrypt their military communications. To calculate your gas expenses, you simply input the number of miles driven! Not only will the program do the math correctly, but it can easily calculate the price of fuel based on where you’re located. Rather than doing the math manually on a napkin, you’re better off relying on a mobile app to do that for you. Let’s say you need to calculate your daily travel spend. When we talk about programming in the computing world, we refer to our use of machines to automate actions that are otherwise repetitive and/or too complex for us to perform. These actions may be subject to conditions, such as, “If the restaurant is fully booked, we’ll eat a hamburger at the beach instead.” The process of writing a program is quite similar. So What Is Programming?Ī “program” is commonly defined as “a plan or schedule of activities, and procedures to be followed.” When you plan out your workday or next holiday, you’re likely defining a structure of consecutive actions that you’ll undertake. What is programming about, and how does it look in practice? In this article, we’ll go over the basics of coding in C++, and you’ll even get to create your first program! Let’s get started. Inside the coffee machine, there’s a small computer running automated instructions - written by a programmer, using a language like C++. It’ll have a program that calculates the optimal amount of water and temperature needed to make you a cup of coffee. Take a household coffee machine, for example.
