mean in the context of pointers and references? dereferencing is the process of accessing the data stored at the memory location pointed to by a pointer or a reference. in other words, if you have a pointer or reference to a piece of data, dereferencing it gives you access to the actual...
Pointers can point to other pointers, even through multiple levels of function calls. How many levels deep can we go?C (C17 + GNU extensions) 1 #include <stdio.h> 2 3 void level4(int*** p4) { 4 printf("Your number is %d\n", ***p4); 5 } 6 7 void level3(int*** p3)...
Both of these error messages are trying to tell us that we're trying to use the + operator (used for string concatenation in Python) between a string and a number.You can use + between a string and a string (to concatenate them) or a number and a number (to add them). But in ...

Suppose we want to find the first pair of elements in an array that sums to a target value. We could use the multiple pointers pattern to solve this problem as follows: Initialize two pointers, left and right, to the first and last elements of the array, respectively. While left is less...
In theory, we’re supposed to be able to use the power of the pointer arithmetic to do clever feats, but does anyone risk doing more than allocating data structures? Is it even a good idea to be too clever with pointers? That’s how code breaks. If you’re able to be clever,...
By default all instance variables and local variables are strong pointers. We generally use strong for UIViewControllers (UI item’s parents) strong is used with ARC and it basically helps you , by not having to worry about the retain count of an object. ARC automatically releases it for ...
For this solution, we will create pointers to the beginning and end of the array which will make sure that the two sides have the same characters in the same order. First, create two pointers— one which points to the beginning of the string and the other which points to the end. The...
