The code that produces the error of the topic is bold.
Thank you.

Your problem is with the percent symbol, "%", as the printf method thinks that it's a format specifier. To use it literally as a percent symbol, you'll need to use two of them in a row. So change this:

"new base salary with 10% increase is: $%,.2f\n"

to this:

"new base salary with 10%% increase is: $%,.2f\n"

The bold tag does not work inside the 'code' tags. Referring to the specific line number where the error is would be the best way.
