Why function overloading in c

Let us take a look at the main method and the output for the above code snippet: The output for the first printf function is 3 and for the second printf function is helloworld: One can also make use of variadic functions for function overloading. Variadic functions can take any number and type of arguments.

Let us look at an example to understand how we can use variadic functions for f unction overloading in C. We want to create an add function which will add any number of arguments passed to it.

The code snippet is given below: stdarg. We are simply looping through the list of arguments sent to the user and adding them. Let us take a look at the main method and the output for the above code snippet. The first printf returns 6 and the second printf returns 9. While calling the function foo at different places… Take a step-up from those "Hello World" programs. Learn to implement data structures like Heap, Stacks, Linked List and many more!

Writing code in comment? The calculated values would be returned to the main method. The strlen method is applied to both string variables to get lengths, and the malloc method has been applied to length to get memory size. Upon the execution of this code, we got the sum of two integers and the concatenated string.

This guide contains the illustration of using an alternative method of function overloading in C. If you have gone through this guide carefully, you would be able to perform function overloading in C easily from now on.

We hope that you may find this article best. Function overloading is a very well-known concept used in object-oriented languages having many functions with the same name and different parameters in a single code. Yet; we can still achieve the same thing with some technique. Pre-requisites Install Ubuntu
