decimal places for HW

[justlearning]

I have this homework problem that needs the array to print out like 1.0, 2.0 ect... I can get it to print out 1,2 ect...I was wondering if someone could tell me how to get it with the one decimal place. I am using doubles and I tried set precision.

Thank you

there is an output set mode function that works for floats as opposed to doubles.

showpoint is the function, and it combines with setprecision. as in:

cout << setprecision (3) << showpoint << 1.00;

setprecision requires #include <iomanip>, and showpoint just requires #include <iostream>
