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. The first step for this is to change the declaration/definition of this function by introducing...
Argument Evaluation and Function Chaining in C++ 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 ...
When we use the Linux or UNIX operating system, we need to include “unistd.h” header file in our program to use thesleep ()function. While using the Windows operating system, we have to include “Windows.h” header to use the sleep () function. So in order to write a cross-platfor...
So in the above dependency chart, we can see the executable ‘main’ at the root. The executable ‘main’ consists of object files viz. main.o, point.o, square.o that is generated by compiling main.cpp, point.cpp and square.cpp respectively. All cpp implementations use header files as ...
Method 3: Using a Function to Initialize Conclusion FAQ Initializing an array of structs in C can be a bit tricky, especially for those new to the language. However, once you grasp the concept, it becomes a straightforward process. This article will walk you through the various methods ...
We would be writing the value function of optional and, like good library developers, we’d try to make it usable and performant in as many use-cases as we could. So we’d want value to return a const reference if the object it was called on was const, we’d want it to return ...

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 ...
