Jun 8, 2013 · In general, the pointer to the element at arr[a][b] can be accessed by arrPtr + a*bSize + b where bSize is the size of the first array dimension (in this case three).

Jan 16, 2023 · So, elements in an array can be accessed using a pointer. Pointer has the capability to store the address, So, we can store the address of the first element of the array and then traverse the pointer till we reach the end element. Methods to store the address of the first elements of the array are mentioned below:

To access the values of the second column by pointer you can use a pointer to the first element of the array and a formula *(row*numberofelementsinarow+(pointer+column) to access whatever you want inside the array changing only the row and column you want in that formula:

Feb 28, 2013 · So, like the other answers hasaid before, it's possible to return the new value of the pointer changing your void buildArray(...) to int** buildArray(...) or sending a pointer on your pointer (it's look difficult), or finally, you're in C++ so you can send a reference, void buildArray(ifstream &file, int**& 2dArray) also 2dArray will be the ...

Feb 7, 2024 · Example 1: Accessing Array Elements using Pointer. Following are some main applications of pointers to arrays in C++: Passing Arrays to Functions: Pointers allow us to pass arrays to functions without copying the entire array. This can improve performance for …

Traversing 2-dimensional arrays using pointers in C++ offers an efficient and flexible approach to access elements of the array. By understanding how pointers and array indexing work together, you can efficiently iterate through multidimensional arrays, perform various operations, and manipulate data with ease.

Apr 13, 2023 · In the table, an array gets stored in form of a pointer pointing towards the first element. The below example is another simplest way of accessing array elements in C++. Example: *(a) - which points to the first element. *(a+1) - which points to second element. Using this concept let us discuss the first method of accessing the arrays-

Sep 10, 2024 · Another common use for pointers to pointers is to facilitate dynamically allocated multidimensional arrays (see 17.12 -- Multidimensional C-style Arrays for a review of multidimensional arrays).

Learn how to access elements of an array using pointers in C++. This guide provides clear examples and explanations for better understanding.

Nov 13, 2024 · In this article, you will learn how to access and manipulate elements of an array using pointers. You'll explore several examples that highlight different techniques and use cases, enhancing your understanding of pointers and arrays in C++.
