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…
Learn how to structure a C file and write a C main function that handles command line arguments like a champ.
and then later, when you reach the end of the loop in line 5, where you write out the GOTO that jumps back to the condition, you simply change the destination of line 2 after the fact. This is usually fairly easy if you write a function for parsing every syntax element. Take the fo...

You can initialize a function pointer by assigning it to a function name, like this: funcPtr = &myFunction;. Invoking Functions: To call a function through a function pointer, you use the (*funcPtr) syntax. For example, to call myFunction through funcPtr, you would write result = (*...
as long as you've used a function before, you merely have to change the value of the seconds once, either by using a variable (calledSNOOZEin the sample code) or directly in the subroutine that processes dough. That can save you a lot of time, because you don't have to hunt through...
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 the notation extern “C”. #include <iostream> extern "C" void func(void) ...
