Arrays
 Chapter 7Imagine that you are writing a program that will calculate the average mark of all students in a class. You know from experience that variables are used to hold data (like a particular student's mark). However, you realize that the class has more than 50 students and so you decide not to use a variable for each individual student. You know that using a variable for each student is overkill. Arrays are incredibly useful in this situation. A variable is a piece of data, whereas an array is a list of data. With an array you can use a single variable student_marks to hold all the marks for each student in the class. This chapter will cover how to create an array, how to manage data in an array, common errors when using arrays, and processing arrays with for loops. | ||
