ICSE − Q & A

while writing a program. should comments even be provided with lines involving declaration and initialization or should it be only based on the program logic?

Math.pow(10,2)= 100.0
Math.pow(5,2)=  25.0
Math.pow(25,0.5)=  5.0


Math.sqrt(9)=  3.0
Math.sqrt(25)=  5.0
Math.sqrt(-25)=  NaN

Math.round(5.4)=  5
Math.round(5.5)=  6
Math.round(5.0)=  5
Math.round(5.6)=  6
Math.round(-5.6)= -6
Math.round(-5.4)=  -5
Math.round(-5.5)=  -5

Math.rint(3.3)=  3.0
Math.rint(3.9)=  4.0
Math.rint(2.5)=  2.0
Math.rint(-4.6)=  -5.0
Math.rint(-4.5)=  -4.0
Math.rint(-4.4)=  -4.0

/*I don't know why but there is a problem with this code.When I'm entering a number for the value of 'n',and press enter after pressing it, instead of appearing one by one, two input lines appear at once,like:
Enter name 1:
Enter name 2: (Both together,and only one value they accept).

Then, it works properly. I'm forwarding the code, anyone who can help, will be appreciated.*/
