When planning out your project, it can be helpful to divide the components into independent parts as much as possible. If possible, try to use separate files (e.g. .h, .c, .hpp, .cpp) to keep functions, classes, etc. outside of your main application file (e.g. main.c). This ...
This article will demonstrate multiple methods about how to return multiple values from a function in C++.ADVERTISEMENTUse struct to Return Multiple Values From a Function in C++Custom-defined struct variables can be used utilized to return multiple values from functions. Namely, we demonstrate an ...
In this article, we’ll take a look at using the function std::getline() in C++. This is a very handy function if you want to read characters from an input stream. Let’s find out how we can use this properly, using some illustrative examples. Basic Syntax of std::getline() in C+...
Once a variable is declared and defined, you need to assign an initial value to it, to make use of the variable in your program. This process of assigning an initial value to variables is known as variable initialization. Why Initialize Variables In C++ Programs? Consider a situation where...

// The default value, -1, indicates that the element is not in the array. int position = -1; // Use parallel_for to search for the element. // The task group enables a work function to cancel the overall // operation when it finds the result. structured_task_group tasks; tasks....
You can copy the code in this article to the message handler function of an event defined in an MFC .cpp file. However, the purpose of the code is to illustrate the process of using the IDispatch interfaces and member functions defined in the Excel type library. T...
I pried open my C book (K&R) to find out what it was. "Ternary Operator" it said. Some people might not know how to use it, so I thought I'd write a simple explanation: Basic Syntax: The ternary operator (?:) is a very useful conditional expression used in C and C++. It's ...
