Feb 7, 2024 · In C++, we can manipulate arrays by using pointers to them. These kinds of pointers that point to the arrays are called array pointers or pointers to arrays. In this article, we will discuss what is a pointer to an array, how to create it and what are its applications in C++.

Nov 21, 2013 · POINTER TO AN ARRAY. Pointer to an array will point to the starting address of the array. int *p; // p is a pointer to int int ArrayOfIntegers[5]; // ArrayOfIntegers is an array of 5 integers, // that means it can store 5 integers. p = ArrayOfIntegers; // p points to the first element of ArrayOfIntegers ARRAY OF POINTERS

Oct 31, 2008 · To call one of those function pointers: You can also initialize p as: As in: // Array of function pointers initialization. int (*p[4]) (int, int) = {sum, subtract, mul, div}; // Using the function pointers. int result; int i = 20, j = 5, op; for (op = 0; op < 4; op++) { result = p[op](i, j); printf("Result: %d\n", result); return 0;

In this tutorial, we will learn about the relation between arrays and pointers with the help of examples. A pointer can store the address of each cell of an array.

Dec 3, 2024 · Pointer to an array: Pointer to an array is also known as array pointer. We are using the pointer to access the components of the array. int a[3] = {3, 4, 5 }; int *ptr = a; We have a pointer ptr that focuses to the 0th component of the array.

Mar 26, 2025 · A pointer to an array is a pointer that points to the whole array instead of the first element of the array. It considers the whole array as a single unit instead of it being a collection of given elements.

In this tutorial, we explored how to use pointers with arrays in C with various examples: Accessing array elements using pointers: Demonstrates how to use a pointer to traverse an array. Modifying array elements using pointers: Shows how pointers can be used to update array values.

May 25, 2011 · How do I define a pointer to an array of pointers? i.e.: The correct answer is: Or just: int* arr [MAX]; The last part reads as "pArr is a pointer to array of MAX elements of type pointer to int". In C the size of array is stored in the type, not in the value.

Arrays and Pointers Relationship between arrays and pointers: • Array name is a pointer constant, it’s value is the address of the first element of the array. • Pointers can be subscribed a[i] = *(a + i) a– address of a[0] (base address or the array) a[i] = *(p + i) points to i-th element of the array

Jul 30, 2024 · Array of Pointers to Character. One of the main applications of the array of pointers is to store multiple strings as an array of pointers to characters. Here, each pointer in the array is a character pointer that points to the first character of the …
