How can I overload equal method to make different objects have same hashcode value in unordered_multimap?

How do you make a constructor? (Novice Level)?

• I am currently working on this problem for a class and i can't get passed the part where i have to make a constructor. Can anybody show me how to do this problem or explain to me how to make a constructor? Thank you! Write the definition of a class Counter containing: An instance variable named counter of type int . A constructor that takes one int argument and assigns its value to counter A method named increment that adds one to counter . It does not take parameters or return a value. A method named decrement that subtracts one from counter . It also does not take parameters or return a value. A method named getValue that returns the value of the instance variable counter .

• Answer:

  class Counter { int counter ; void increment() { counter++ ; } void decrement() { counter-- ; } int getValue() { return counter ; } public: Counter(int x) // constructor has same name as that of class and NO return type { counter=x; } } ; Hope it helps....
