Can we multiply 2 pointers in C?

Can we multiply 2 pointers in C?

2 Answers. Multiplication and division of pointers are not allowed in C.

How do you put 2 numbers on a pointer?

Add two Numbers using Pointer in C++ Then make two pointer type variable of same type say *ptr1 and *ptr2 to initialize the address of both the variable (that holds numbers) and using another variable say sum, store the addition of the two number, i.e., sum = *ptr1 + *ptr2 and display the value of sum on the screen.

How do I add a value to a pointer?

Logic to add two numbers using pointers

1. & (Address of) operator – When prefixed with any variable returns the actual memory address of that variable.
2. * (Dereference) operator – When prefixed with any pointer variable it evaluates to the value stored at the address of a pointer variable.

How do you use pointers to multiply?

Methods

1. Create two variables to store two numbers as input (num1 and num2) provided by the user.
2. Create two pointer variables to store the address of the numbers: num 1 and num2.
3. Create a variable to store the sum of these numbers: sum.
4. Request the user to enter the first input to store variable num1.

Why 2 pointers can not be added multiplied or divided but can only be subtracted?

Why only subtraction of addresses allowed and not division/addition/multiplication. Why Subtraction is allowed? Two addresses can be subtracted because the memory between the two addresses will be valid memory. It is obvious that memory between these two addresses is valid.

How do you use Adding pointers in C?

Program Explained

1. Declare three variables say num1, num2, and sum of int (integer) type.
2. Here first two variable stores the two number entered by user at run-time.
3. And the third variable, sum will be used to store the summation of given two number using pointer.

Can two pointers be added?

You can add a distance to a pointer and get another pointer. You can even subtract pointers. However, you cannot add two pointers together, nor multiply a pointer by a pointer or a scalar.

What is a double pointer in C?

C++Server Side ProgrammingProgrammingC. A pointer is used to store the address of variables. So, when we define a pointer to pointer, the first pointer is used to store the address of the second pointer. Thus it is known as double pointers.

What is pointers in C?

The pointer in C language is a variable which stores the address of another variable. This variable can be of type int, char, array, function, or any other pointer. int* p = &n // Variable p of type pointer is pointing to the address of the variable n of type integer.

Can 2 pointers be added?

How to find product of two numbers in C?

In the C programming language, we can use the pointer variable to find product of two numbers . In this article, we are going to learn how to d isplay the product of two numbers using the pointer variable. Create two variables to store two numbers as input ( num1 and num2) provided by the user.

What are the two common operators used with pointers?

There are two common operators used with pointers – & (Address of) operator – When prefixed with any variable returns the actual memory address of that variable. * (Dereference) operator – When prefixed with any pointer variable it evaluates to the value stored at the address of a pointer variable. Program to add two numbers using pointers

How to D isplay product of two numbers?

In this article, we are going to learn how to d isplay the product of two numbers using the pointer variable. Create two variables to store two numbers as input ( num1 and num2) provided by the user. Create a variable to store the sum of these numbers: sum. Using scanf () function, store the second input value in num2.

How to store the second input value in num2?

Using scanf () function, store the second input value in num2. Find the product of two number using their addresses – find the product of num1 and num2 using their addresses or multiply them using the pointer variables.
