Examples of the one-dimensional array declarations, int xNum[20], yNum[50]; float fPrice[10], fYield; char chLetter[70]; The first example declares two arrays named xNum and yNum of type int. Array xNum can store up to 20 integer numbers while yNum can store up to 50 numbers.
In this tutorial, you will learn to work with arrays. You will learn to declare, initialize and access array elements of an array with the help of examples. An array is a variable that can store multiple values.
Pointers to arrays A pointer to an array points to the first element in the array. We can use pointer arithmetic or bracket notation to access the elements in the array. If we have a pointer, we can actually change the value of the pointer to point to another place in the array. Address Value 0x7ffeea3c9498 42 0x7ffeea3c9494-5 0x7ffeea3c9490 14

Arrays are essential data structures that allow us to store and manipulate multiple values of the same data type. By the end of this chapter, you'll have a solid understanding of how to declare and initialize arrays, unlocking a powerful tool in your programming arsenal.
To declare an array in C, a programmer specifies the type of the elements and the number of elements required by an array as follows: type arrayName [ arraySize ]; This is called a single-dimensional array. The arraySize must be an integer constant greater than zero and type can be any valid C data type.
Array. solves the problem of storing a large number of values and manipulating them. is a data structure designed to store a fixed-size sequential collection of elements of the same type, i.e., it is a collection of variables of the same type. Array Declarations.
