Question

Suppose that x = 1565.683,y = 85.78,and z = 123.982.What is the output of the following statements? 
cout << fixed << showpoint;
Cout << setprecision(3)<< x << ' ';
Cout << setprecision(4)<< y << ' ' << setprecision(2)<< z << endl;
A) 1565.683 85.8000 123.98
B) 1565.680 85.8000 123.98
C) 1565.683 85.7800 123.98
D) 1565.683 85.780 123.980

The first cout statement sets the precision for all the subsequent floating-point value outputs. 
The second cout statement sets the precision of x to 3 decimal places with fixed point notation (i.e., always displaying the decimal point even if there are no decimal places). 
The third cout statement sets the precision of y to 4 decimal places and z to 2 decimal places. 
Therefore, the output would be: 
1565.683 85.7800 123.98
