Another use of void pointers in C is infunction pointers, which are variables that store the memory address of a function. Void pointers can be used to store the memory address of any function, regardless of its return type or parameter list, allowing for more flexibility in function pointer ...
#include <iostream> class MyClass { public: MyClass() { std::cout << "Constructor called!" << std::endl; } }; int main() { MyClass obj; return 0; } In this, we’ve retained the essential parts of the previous example while removing unnecessary whitespace and comments. The output...
In a similar vein, when talking aboutstdin,stdout, andstderrit is convenient to trot out the accepted axiom that a process neither knows nor cares where its three standard streams are terminated. Should a process care whether its output is going to the terminal or being redirected into a file?
C++ is an object-oriented programming (OOP) language that is viewed by many as the best language for creating large-scale applications. C++ is a superset of theClanguage. A related programming language,Java, is based on C++ but optimized for the distribution of program objects in a network s...

I would love to see how a std::atomic of a given type is aligned, for example. Being able to know when an atomic is not atomic (and using a hidden mutex) would also be useful. Stay informed Get notified when new posts are published. Subscribe By subscribing you agree to our Terms...
} static void final_release(std::unique_ptr<Sample> self) noexcept { // Move 'self' as needed to delay destruction. } }; In the example below, once the MainPage is released (for the final time), final_release is called. That function spends five seconds waiting (on the thread pool)...
