Course Description

Computer programs have limited use if the underlying programming language has no way of storing large amounts of data internally without accessing an external device. The most common way to store data in C is by using an array—a variable that allows you to store multiple data items of the same data type, with access to individual data elements determined by index position.

In these lessons, we provide all the information you need to use C arrays effectively. We’ll start with an explanation of how arrays are declared. Then we’ll discuss how you can both declare an array and store initial data in that array. Next, you’ll learn how to store and access the data in an array other than by initializing it. Finally, we’ll end with an example of how to use arrays to solve problems.

What You'll Learn

  • Understand what an array is and why arrays are used in programming
  • Declare a one-dimensional array in C
  • Declare and initialize an array in a single statement
  • Assign and access data stored in an array beyond initialization
  • Use arrays to solve common computational problems

Key Takeaways

  • An array is a variable that stores multiple data items of the same data type, with individual elements accessed by index position.
  • Arrays are the most common way to store data internally in C, addressing the limitation of languages that cannot store large amounts of data without an external device.
  • The course covers declaring arrays, declaring and initializing them together, assigning and accessing data, and applying arrays to solve problems.
  • Data in an array can be stored and accessed in ways other than through initialization.
