- 25. 25 How to program? •Before a program is written, the programmer must clearly understand what data are to be used, the desired result, and the procedure used to produce this result. • The procedure, or solution, selected is referred to as an algorithm. • In essence, an algorithm answers the question “What method will you use to solve this problem?” An algorithm is defined as a step-by-step sequence of instructions that must terminate and that describe how the data is to be processed to produce the desired outputs.
- 26. 26 How to program? Example Supposewe want to calculate someone’s gross pay. How the program should be designed? 1. Display a message on the screen asking “How many hours did you work?” 2. Wait for the user to enter the number of hours worked. Once the user enters a number, store it in memory. 3. Display a message on the screen asking “How much do you get paid per hour?” 4. Wait for the user to enter an hourly pay rate. Once the user enters a number, store it in memory. 5. Multiply the number of hours by the amount paid per hour, and store the result in memory. 6. Display a message on the screen that tells the amount of money earned. The message must include the result of the calculation performed in Step 5.
- 27. 27 Exercise The following pseudocodealgorithm has an error. The program is supposed to ask the user for the length and width of a rectangular room, and then display the room’s area. The program must multiply the width by the length in order to determine the area. Find the error. area = width * length. Display “What is the room’s width?”. Input width. Display “What is the room’s length?”. Input length. Display area.

Editor's Notes
- #9 4 ways learning to drive a car is like learning to code It gives you independence. Before I always had to ask my mom or my husband to drive if I needed to use a car, now I can do it myself. For coding tasks, you may depend on a lab mate or software like SPSS or SAS, but it’s just nicer if you can do it yourself. It is not about being the best driver or the best coder. I can drive, but I will never be the best driver in any group of people. But who cares? I get from A to B safely and that’s what matters. For coding, it’s the same thing. If you want to use coding in your studies or work, you don’t need to be the best coder. You just need to get from A to B (or from raw data to a nice plot). Practice is key. When I first got my license, I didn’t have access to a car and I didn’t drive for a few years. Clearly, that was not very good for my driving skills or confidence. Later, when I did have a car available, I would regularly take it to drive to a friend who lived just 5 miles away to have a coffee. These short trips helped me feel comfortable in the car. If you’ve learned some coding skills, try to find a way to keep using it, even if it is just for short 5-mile drives. It opens up jobs and opportunities. For many jobs, you need to be able to drive a car. Not just jobs such as taxi driver, but also jobs that are utterly unrelated to driving. For me, I got the job at SFSU when I lived in Menlo Park. Public transport from Menlo Park to SFSU is so bad, that I really couldn’t do the job if I wasn’t able to drive to the SFSU campus. With coding it can be the same thing. I am a biologist and I am interested in evolution of viruses and bacteria – yet I couldn’t do that research without coding skills. Happy coding!
