Variables
Saving and reusing data effectively in programming often requires the use of variables.
To ensure clear and error-free programming, certain rules must be followed when naming variables. Here are some guidelines:
- Variable names must not start with a number or with a period followed by a number;
- They should not include the
%symbol; - They must not begin with an underscore
_; - They can start with a period if it is not followed by a number.
Choosing meaningful variable names is considered best practice. For instance, naming a variable year to store the value 2020 is more intuitive than using nondescript names like a or b. While this isn't mandatory, it significantly enhances code readability for both the author and others.
To assign a value to a variable, the assignment operator = is used. For example, year = 2020 assigns the value 2020 to the variable named year:
12year = 2020 cat(year)

Regarding the deposit task, let's assign the relevant data to variables using the assignment operator:
- Assign the initial amount of money,
2000, to the variable namedinitial_money. - Assign the interest rate,
13, to the variable namedinterest_rate. - Assign the number of years,
4, to the variable namedn_years. - Use the
cat()function to display the values ofinitial_money,interest_rate, andn_yearsin the order they were created.
