We’ve learned that C++ supports two sorts of variables so far: An ordinary variable is one that holds the value of a certain type. For example, let’s say we make a variable of type int, which means it can hold…

A Null Pointer is a pointer that doesn’t point to any memory location. It saves the segment’s base address. The null pointer is used to hold null values, and the type of the pointer is void. A null pointer is a special…
A pointer is a variable that stores the address of another variable, as we already know from “what is a pointer.” The (*) represents the dereference operator, which is also known as an indirection operator. Dereferencing a pointer occurs when…
So far, we’ve learned that the address associated with a pointer must be of the same type as the pointer declaration. If we define an “int” pointer, for example, it cannot point to a float variable or any other type of…
In C/C++, a constant pointer can’t change the address of the variable it’s pointing to, so the address stays the same. As a result, we can conclude that if a constant pointer points to one variable, it cannot point to…
The sizeof() operation determines the size of a data type, a constant, or a variable. It’s a compile-time operator since it calculates the size of any variable or constant at build time. The sizeof() operation calculates the amount of RAM…
Wild pointers are uninitialized pointers that point to any arbitrary memory location, potentially causing a program to crash or behave improperly. It’s important to remember that a pointer p that points to a known variable is not a wild pointer. In…
Dangling/wild pointers are the most common pointer and memory management problems. A dangling pointer is a sort of initialized pointer in C that occurs when the programmer fails to initialize the pointer with a proper location. When an object is…
On the pointers, we can do arithmetic operations such as addition, subtraction, and so on. However, because the address is stored in the pointer, the result of an arithmetic operation on the pointer will also be a pointer if the…
The term “pointer-to-pointer” or “double pointer” refers to a pointer that holds the address of another pointer. We’ll learn what a double pointer is, how to declare them, and how to use them in C / C++ programming in this…
In the C/C++ programming language, a pointer is a variable that holds the address of another variable. The type of this variable can be int, char, array, function, or any other pointer. The pointer’s size is determined by the architecture.…
In this article, you will see the Complete Pointer Reference In C/C++ and get a proper understanding of it. Here you will know about what is a pointer and how to deal with it means complete Learn Pointer In C…

In this post, We are going to discuss the program, Given two numbers A and B, the challenge is to use a stack to eliminate the trailing zeros from the sum of the two numbers. Example: Approach: The string and…
In this post, we’ll look at how to use *args and **kwargs in Python, as well as some examples. We frequently need to supply values to a function when writing it. Function arguments are the names given to these items.…
In this post, solve the merge sort using the inplace_merge() function. Given an arrayA[] of size N, the task is to sort the array in increasing order using In-Place Merge Sort. Example: Steps To Solve: The objective is to merge the sorted arrays in O(1) space…
