in c++

Q7: Continue with Integer class: a) Copy the previous program to a new file. b) Overload the postfix -- operators, so return a Word object with remove last character of value. c) Overload the pretfix -- operators, so return a Word object with remove first character of value. d) Overload the subscript i operator, terminate program if index is bigger or equal than size. Return i-th character based on the given index. Class template (complete following function): class Wordt friend Word operator-//postix friend Word operator-//preffix char& operator] } Use following main() to test your class. int main() { Word a("abc"),b; cout Answer: 7 CO 10 2.cpp 1 #include 2 using namespace std; 3 class Word { 4 private: 5 string value; 6 int size; public: Word(){value = "empty"; size = 0;} 9 Word(string val): Word(){value = val;size = val.length(); } 11 12 void setValue(string v) {value = v;} 13 string getValue() {return value; } 14 void setSize(int s){size=s;} int getSize(){return size;) }; 18 int main() { Word a,b("abc"); 21 22 cout Answer: 7 CO 10 2.cpp 1 #include 2 using namespace std; 3 class Word { 4 private: 5 string value; 6 int size; public: Word(){value = "empty"; size = 0;} 9 Word(string val): Word(){value = val;size = val.length(); } 11 12 void setValue(string v) {value = v;} 13 string getValue() {return value; } 14 void setSize(int s){size=s;} int getSize(){return size;) }; 18 int main() { Word a,b("abc"); 21 22 cout
