However, the heap memory maintains the memory until it's deallocated manually by a programmer. The stack memory can be used to store them for a small amount of memory. It causes overflow when the stack is exceeded to limit. On the other hand, the heap has no limit for the size of me..

Function overloading has rules first, it should have the same function name. second, the number of arguments or the types should be different. Example code Result When function 'func(4)' is called in main, function 'func(int a)' executed because it coincides with the..

Call by reference & Call by value with example code Call By ValueIf you change the value of the parameter. It modifies the value in the current function only.
