Let us learn how to add two numbers using pointers in C programming using user-defined functions with an output.
The C program for addition of two pointers makes use of the de-reference operator, also known as the asterisk (*). The user-defined function used here makes use of the call by reference approach.
What is a Pointer?
A pointer is a variable which can be used to store the memory address of another variable which is of the same data-type.
Note: This program to add two integers using pointers in C programming is compiled with GNU GCC compiler with gEdit editor on Linux Ubuntu 14.10 operating system.
There are many other arithmetic operations that can be performed on pointers in C programming, and they’re enlisted below:
C Program To Add Two Numbers using Pointers and Functions
int add(int *x, int *y);
int num1, num2, res;
printf("\nAdd First Number:\t");
printf("\nAdd Second Number:\t");
res = add(&num1, &num2);
printf("\nAddition of Two Numbers: %d", res);
int add(int *x, int *y)
temp = *x + *y;
