1. Motivations Sometimes, we need to execute something before and after main(), such as: I want to simulate a construtor & destructor in C. I need the invoking count of construtor and destructor strictly be the same. Or else, there may be memory leak. To do this, one simple solution...
Learn how to structure a C file and write a C main function that handles command line arguments like a champ. I know, Python and JavaScript are what the kids are writing all their crazy "apps" with these days. But don't be so quick to dismiss C—it's a capable and concise language...

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....
This example has been included in the documentation for MATLAB 7.5 (R2007b).
I want to use "callback functions" in C/C++ DLL, so I want to set "function pointers" as arguments of C/C++ DLL adaptors in TestStand.Could you show me the way how TestStand C/C++ DLL adaptor work with such function pointers as arguments?
How to write a file in C++? Whenever we want to write the datas using file stream functions we used basic insertion operators like <<its just use as an operator to print the output datas to the user screen. The basic difference between this write files and other default file functions lik...
Let's write a very simple program, where we will declare and define an array of integers in our main() function and pass one of the array element to a function, which will just print the value of the element.#include<stdio.h> void giveMeArray(int a); int main() { int myArray[]...
In this section we will discuss on how to call C++ functions from C code. Here is a C++ code (CPPfile.cpp) : #include <iostream> void func(void) { std::cout<<"\n This is a C++ code\n"; } We will see how the function func() can be called from a C code. ...
