One article just doesn’t suffice for a topic as exhilarating as pointers. You now know what a pointer is and the basic functionality that it provides in the context of C programming. In the next article, we’ll be able to dive into the action, i.e., how to actually use pointers ...
This study lesson will talk about how to create and process strings using pointers in C Programming. By learning to use a pointer when calling a...
Yes, many programming languages allow you to declare a variable without assigning an initial value. The variable will have an undefined or default value until a value is explicitly assigned to it. What is a declaration file in TypeScript?
What is a dangling pointer in C++?C++ Programming Interview Question Answer:A dangling pointer arises when you use the address of an object afterits lifetime is over. This may occur in situations like returningaddresses of the automatic variablesfrom a function or using theaddress of the memory...

What is a Pointer? “A pointer is a variable that holds the memory address of another variable”. In very short term, we can say that a “pointer is a memory address”. The address, that a pointer variable holds, directly points to the value stored in memory and that value is ...
A pointerwith no address is known as a null pointer, while a pointer with no data type is called a void or general-purpose pointer. Have a look at the below program to understand this data type in-depth: #include<br> int main() {<br> ...
A pointer is a very powerful and sophisticated feature provided in the C language. A variable defined in a program the compiler allocates a space in the memory to store its value. The number of bytes allocated to the variable depends on its type. For ins
Then, we use theprintf() functionto display a message and the address of the num on the console. The message includes aformat specifier %p, indicating that a pointer's address will be inserted in its place. The ptr variable, which holds the memory address of num, is passed as an argume...
This is not a course for beginners. This is an intermediate level course. Who has the basic knowledge in C programming and what to move to the Advance Level can really interested about pointer can take the course. If you’ve struggled with pointers and have a knowledge gap in this area ...
