The R programming language has many prebuilt functions, but the goal of this post is to give you a few examples of how to write a function in R. A function in R is basically built around the following structure: function ( arglist ) {body} The body is where you are going to write ...
Use the return Statement to Call a Function Within a Function in C++ Use std::pair to Return Two Values From the Function in C++ Use Function Pointers to Call a Function Within a Function in C++ Conclusion C++ is a powerful and versatile programming language that allows you to create...
In this article, I'll explain how to structure a C file and write a C main function that handles command line arguments like a champ.Me: a crusty Unix system programmer. You: someone with an editor, a C compiler, and some time to kill....
Bitwise ‘AND’ (‘&’) is used to check if a specific permission is present, and bitwise NOT (‘~’) is used in combination with AND to revoke permission (WRITE, in this case). Difference Between Enum and Macro We use enums and macros for different purposes in C programming. Enums ...
In this tutorial, we’ll explore a C++ programming problem that involves determining if a test point lies within a triangle. We’ll create a function that takes four pairs of (x, y) coordinates. The…
What is Assert in C Programming? The assert keyword is used to perform an expression as a function parameter, and it evaluates it during memory allocation. So we can use the malloc() method to write and evaluate expressions on the variable. If the expression evaluation fails or returns the ...
If you’re in a shell, the output may look weird, but that’s because multiple processes ran in parallel! Both the outputs were indeed printed, so we’ve been able to resolve our problem. We learned about using the execvp() function in C / C++, to execute other programs from our C...
In a stack, the insertion and deletion of elements happen only at one endpoint. The behavior of a stack is described as “Last In, First Out” (LIFO). When an element is “pushed” onto the stack, it becomes the first item that will be “popped” out of the stack. To reach the ...

There are times when it is required to mix the C and C++ code together. For example, while using a legacy C code or while using a specific C library the provides your C++ code with some specific functionality. So, some special steps are to be taken care
