Understanding Functions and Procedures in Programming

Functions and procedures are important ideas in programming. They help us organize and simplify the work we do with computers. Let’s look at some examples that show how these ideas are used in everyday life.

1. Banking Systems:

   • Functions: A function can figure out how much interest you earn on your savings. It uses the amount of money you have and the interest rate to give you the total interest earned.
   • Statistics: In Sweden, the average interest you earn on savings accounts is about 1%. This helps banks decide how to manage people’s money.

2. Weather Forecasting:

   • Procedures: A procedure is like a recipe for gathering weather data. It includes steps for collecting information, checking for mistakes, and making a weather report.
   • Statistics: To predict the weather accurately, experts study past weather data. Their methods can be about 90% correct for short-term forecasts.

3. E-commerce Platforms:

   • Functions: Functions can calculate sales tax. For example, a function can use the total price and the tax rate to find out how much you’ll pay in total.
   • Statistics: In 2021, online sales in Sweden reached around $1.5 billion. This shows how important it is to have accurate calculations in e-commerce.

4. Health Monitoring Applications:

   • Procedures: A procedure can track how much exercise a person does. It calculates the calories burned based on what type of activity they do and for how long, then updates their profile.
   • Statistics: Research shows that people who use fitness apps exercise 25% more because of the features in these apps.

These examples help us see how functions and procedures work in real life. They show how important these concepts are for making programs easier to use and more effective. By using programming techniques, developers can create better applications that fit people's needs.
