Arrays provide a way to store multiple elements from "summary" of C Programming Language by Brian W. Kernighan,Dennis Ritchie
Arrays are a fundamental concept in the C programming language. They provide a convenient way to store multiple elements of the same data type in a single variable. When you declare an array in C, you are essentially creating a collection of variables that are all of the same type. For example, if you want to store a list of integers, you can declare an integer array and specify the number of elements it will hold. Each element in the array can be accessed using an index that starts at 0 and goes up to the size of the array minus one. This allows you to easily iterate over the elements of the array using a loop. Arrays in C are zero-indexed, meaning that the first element in the array is at index 0, the second element is at index 1, and so on. This can sometimes lead to off-by-one errors if you are not careful in your indexing. It is important to keep track of the size of your array and ensure that you do not try to access elements beyond its bounds. Another important aspect of arrays in C is their fixed size. Once you declare an array with a certain number of elements, you cannot change the size of the array at runtime. This means that you need to know in advance how many elements you will need to store in the array. Despite these limitations, arrays are a powerful tool in C programming that allow you to efficiently store and access multiple elements of the same type. They are widely used in a variety of applications, from simple data storage to complex algorithms. By understanding how arrays work and how to manipulate them, you can unlock the full potential of the C programming language.
