Complete the code to output $"$q $="$ followed by the value of q to four digits after the decimal point. On the same line, output $"$ when x $="$ followed by the value of x to three digits after the decimal point. End with a newline.

Ex: If the input is $3\mathrm{.}600,$ then the output is:

q $=-148\mathrm{.}8600$ when x $=3\mathrm{.}600$

Note: setprecision$($X$)$ can be used in an output statement to print a double to X digits after the decimal point.
