Individual Project III for C++ Programming (Operator Overloading) This project will accomplish a special string class FumString, the operator for the object of this class is defined as follow . Addition: the result for string A plus string B is to comnect the string B to the tail of the string A, if there is the same letter they encounter, the two letters will be neutralized, and so on. For example abe+ cbe result: ae Subtraction: the result for string A minus string B is to search the first letter of the string B in the string A, if there is the same letter in the string A, delete it from the string A, and so on. For example abc- cde result: ab Multiplication: the result for string A times string B is to insert the first letter in the string B after the first letter in the string A, and insert the second letter in the string B into after the second letter in the string A, and so on. For example
