Learn: How to overload pre-increment operator by using the concept of nameless temporary objects in C++, this articles contains solved example on this concept? Prerequisite: operator overloading and its rulesWhat are nameless temporary objects in C++?
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 ...
There are three types of constructors in C++, namely default, parameterized, and copy constructors. Default Constructor: A default constructor takes no arguments. Thus, it is called, by default, when an object is created without any arguments. The default constructor initializes the data members...
5. Template methods/functions are not always inlined (their presence in an header will not make them automatically inline). 6. Most of the compiler would do in-lining for recursive functions but some compiler provides #pragmas- microsoft c++ compiler - inline_recursion(on) and once can also...

Similarly, protected members can only be accessed by derived classes and are inaccessible from outside. However, there is a feature in C++ called friend functions that break this rule and allows us to access member functions from outside the class. ...
1在C语言中,如果函数在声明之前被调用,那么编译器假设函数的返回值的类型为INT型, 所以下面的code将无法通过编译: #include <stdio.h>intmain(void) {//Note that fun() is not declaredprintf("%d\n", fun());return0; }charfun() {return'G'; ...
