Once you store the address of first element in p, you can access array elements using *p, * (p+1), * (p+2) and so on. Below is the example to show all the concepts discussed above −. p = …

In C++, for most use cases life is easier with a std::vector. Now you can use push_back () to add new pointers to it and [] to index it. It is cleaner to use than the ** thing. If the size of the array …

Here's a code snippet to illustrate an array of pointers: int values[] = {10, 20, 30}; int * pointers[3]; // Array of pointers for (int i = 0; i < 3; i++) { pointers[i] = &values[i]; // Assign addresses of …

This C++ program demonstrates the use of a pointer to iterate through an array. The output will display the values of each element in the array, printed one at a time, as the pointer p is …
