In this example, the function call in main, work( count, lift ); passes an integer variable, count, and the address of the function lift to the function work. Note that the function address is passed simply by giving the function identifier, since a function identifier evaluates to a point...

are usually passed by reference using pointers, but passing structs by value is also supported. This is done by specifying theStructdata type to the function definition and passPointerarguments to populated structs. Copies of the structs will be made from the pointers during the function call. ...
" to define an inline function inline int sum(int a, int b) { // Definition of inline function return a + b; } int main() { int a = 10, b = 30; int result = sum(a, b); // Function call to inline function // Compiler replaces sum() with the inline function definition....
To call the constructor, we use constructor chaining. The basic purpose of using abstract classes is to maintain a uniform interface inside all derived classes. This means if there are two classes inheriting from an abstract class, both classes should provide the implementation of a pure virtual...
