std::string is pretty much just a pointer wrapped up in a class so you don't have to worry about new-ing and deleting a char buffer. 1234567 class string { private: char* data; public: string() : data(nullptr) {} // etc }; so by new-ing you are doing one more new, for the...

Mutexes that only use two bits. Either stored in a byte, or in the bottom bits of a pointer - two_bit_mutex/benchmark.cpp at main · skarupke/two_bit_mutex
You never instantiate a B object. This is a problem, because in B::init you try to set a member variable of an object that doesn't exist. That and the fact that your mainB pointer could point anywhere are enough to get you a nice seg-fault :D Sep...

If dealing with Integer objects and there’s a possibility of null values, ensure appropriate null checks before using methods likecompareToorequalsto avoidNullPointerExceptions. When comparing primitive integers, prefer using the==operator over methods likeequals. The==operator is more performant and...
To swap two numbers using pointers, we will first store the values in normal variables and declare two pointers to them. Then we will declare a pointer temp. Then, with the help of ’*’ operator, we will store the value of first pointer in temp. Then we will change the value in fir...
