Printing the correct number of decimal points with cout

Question

I have a list of float values and I want to print them with cout with 2 decimal places.

For example:

10.900  should be prin         


        

Answer 1

I had this similar problem in a coding competition and this is how I handled it. Setting a precision of 2 to all double values

First adding the header to use setprecision

#include

Then adding the following code in our main

  double answer=5.9999;
  double answer2=5.0000;
  cout<

Output:

5.99
5.00

You need to use fixed for writing 5.00 thats why,your output won't come for 5.00.
