Chapter 3, Problem 14RQE

Program Plan Intro

Precision:

The keyword used to set precision in C++ is “setprecision”.

• It is used to set the decimal precision to display the number as floating-point value.
• With the usage of “setprecision” and “fixed” keywords, the trailing zeros are usually exposed.
• The keyword “setw” is used to determine the least number of positions in the console.
• The trailing zeros are displayed only if “showpoint” manipulator is used.

Left manipulators:

• Normally, the output is always displayed in right-justified format.
• It order to display the output in left-justified, the keyword “left” is used.
