Objective

The objective of this assignment is to practice using loops. You will create

several short programming assignments to get more familiar with C$++$ looping

concepts. Please read the full document carefully before starting.

Requirements and Deliverables

This lab has three elements $($A $-$ C$).$ Required actions include:

Develop, build and execute the code for each element

Upload your final source code for each lab element to the appropriate

CANVAS upload site. Use the following names for your source files:

Lab Element A $---$ Calculate and Display a Logarithm Table

Write a program that uses a loop to produce the following logarithm table on

screen. Note that the value $x$ starts at $1,$ and the step $($the difference of $x$

between two rows$)$ is determined by the value of $x$; that is the step size, $s=$

$f(x).$ For example,

when $1x9,s(x)=1$

when $10x99,s(x)=10$

when $100x999,s(x)=100$ and so forth

See table below for further illustration.

When the program starts, it should prompt the user how many rows it will

calculate. Once the user enters this information, the table will be

calculated and displayed on screen.

NOTES:

You do not have to use subscript fonts for the table header. For example,

$lo{g}_{10}(x)$ can be displayed as $log10(x)$

To calculate the step size, $s(x),$ it is recommended that you utilize the

properties of logarithms. For example, for the base $10$ logarithm, it

follows that when $x=120$ :

$log10(120)=log10(1\mathrm{.}2**{10}^2)=log10(1\mathrm{.}2)+log10({10}^2)=2+0\mathrm{.}07918=2\mathrm{.}07918$

For $x=120,$ you want $s(x)=2.$ Think about how you can obtain this in

your C$++$ code. What happens if$,$ say, $x=12$ or $x=1200?$

You can use the following C$++$ functions:
