Digital circuits that use memory elements for their operation are known as Sequential circuits. Thus Sequential circuits are implemented by combining combinational circuits with memory elements.
--or--This type of system uses storage elements called flip-flops that are employed to change their binary value only at discrete instants of time. Synchronous sequential circuits use logic gates and flip-flop storage devices. Sequential circuits have a clock signal as one of their inputs. All state transitions in such circuits occur only when the clock value is either 0 or 1 or happen at the rising or falling edges of the clock depending on the type of memory elements used in the circuit.
{
private:
double x,y;
static int z;
public:
Complex(double = 0.0);
friend ostream& operator<<(ostream&, const Complex&);
static int doSomething( ) { z = 2 * y; return z; }
};
a. What is wrong in the definition of member function doSomething().
b. What will be the effect of writing the friend function operator<<(…) in private part of the above class
a) Static keyword because using static key word we are declaring a static member function doSomething(). Which can not use non static data members.
b) There will be no effect on friend function if we write it in private part. Friend function is a friend function and can use any private or public data member of the class. Where ever we declare it in class body.
