Advanced C++ Programming Cookbook

How it works...

In this recipe, we will learn how to monitor how much memory an application is consuming, as well as the different ways that C++ can allocate memory behind the scenes. To start, let's look at a simple application that does nothing:

int main(void){}

As we can see, this application does nothing. To see how much memory the application has used, we will use Valgrind, a dynamic analysis tool, as follows:

As shown in the preceding example, our application has allocated heap memory (that is, memory allocated using new()/delete() or malloc()/free()). To determine where this allocation occurred, let's use Valgrind again, but this time, ...
