Addition of Two Numbers Using Pointers 


Write a C Program for Addition of Two Numbers Using Pointers. Here’s simple Program to Add Two Numbers Using Pointer in C Programming Language.


What are Pointers?


A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. Like any variable or constant, you must declare a pointer before using it to store any variable address.

The general form of a pointer variable declaration is

  • type *var-name;

Here, type is the pointer’s base type; it must be a valid C data type and var-name is the name of the pointer variable.

The asterisk * used to declare a pointer is the same asterisk used for multiplication. However, in this statement the asterisk is being used to designate a variable as a pointer.

The unary or monadic operator & gives the “address of a variable’”.

The indirection or dereference operator * gives the “contents of an object pointed to by a pointer”.


Below is the source code for C Program for Addition of Two Numbers Using Pointers which is successfully compiled and run on Windows System to produce desired output as shown below :


SOURCE CODE : :


/*  C Program for Addition of Two Numbers Using Pointers  */

#include<stdio.h>

int main()
{
   int num1, num2, *ptr1, *ptr2;
   int sum;

   printf("Enter 1st number :: ");
   scanf("%d",&num1);
   printf("\nEnter 2nd number :: ");
   scanf("%d",&num2);

   ptr1 = &num1;
   ptr2 = &num2;

   sum = *ptr1 + *ptr2;

   printf("\nAddition of two numbers = %d\n\n", sum);

   return 0;
}

Output  : :


/*  C Program for Addition of Two Numbers Using Pointers  */

Enter 1st number :: 6

Enter 2nd number :: 9

Addition of two numbers = 15


Process returned 0

Above is the source code for C Program for Addition of Two Numbers Using Pointers which is successfully compiled and run on Windows System.The Output of the program is shown above .
