Expert Solution & Answer
Chapter 5, Problem 1AW
Explanation of Solution
Methods:
- The methods could be used to break a complex program into small pieces.
- The “void” method simply executes a statements group and then terminates.
- A value returning method would return a value to statement that has called it.
- While calling a method, program would branch to that method.
- It would then execute statements in its body.
- The values that are sent into a method are termed as “arguments”.
- A “parameter” denotes a special variable that holds a value that is being passed into a method.
- The “passed by value” means that only copy of a value of argument is been passed into parameter variable.
- A “local variable” is been declared inside a method, it is not accessible to statements outside method...

Design and specify a method union for the ArrayBag that returns as a new bag the union of the bag receiving the call to the method and the bag that is the method's parameter. The method signature (which should appear in the .h file and be implemented in the .cpp file is: ArrayBag<T> bagUnion(const ArrayBag<T> &otherBag) const; This method would be called in main() with: ArrayBag<int> bag1u2 = bag1.bagUnion(bag2); Note that the union of two bags might contain duplicate items. For example, if object x occurs five times in one bag and twice in another, the union of these bags contains x seven times. The union does not affect the contents of the original bags.
