Which constructor is invalid for class cat?

Options
1) void cat :: cat() { feet=4;}
2) cat::cat(int f){feet=f;}
3) cat::cat(void){feet=8;}
4) cat::cat(int f){this->feet=f;}

• void cat::cat(void ){feet=8;}

• 1, return type of constructor is nothing not even void

• Option [1] since a constructor for a class can have no return type, not even "void". Hence the constructor function definition is not valid.
