IN C$++,15\mathrm{.}27$ LAB: Mileage tracker for a runner

Given the MileageTrackerNode class containing the number of miles a runner runs on a certain date, complete main$()$ to perform the following tasks:

$1.$ Read the number of nodes in the linked list from user input, followed by the number of miles and date of each node.

$2.$ Use the MileageTrackerNode's InsertAfter$()$ function to insert each node according to the input sequence $($i$.$e$.$ insert each node after the last node$).$

$3.$ Print the entire linked list using the MileageTrackerNode's PrintNodeData$()$ function. DO NOT print the head node that does not contain user$-$input values. Hint: PrintNodeData$()$ only outputs values in one node; therefore, iterate through the linked list.

Ex$.$ If the input is:

$3$

$2\mathrm{.}2$

$7/2/18$

$3\mathrm{.}2$

$7/7/18$

$4\mathrm{.}5$

$7/16/18$

the output is:

$2\mathrm{.}2,7/2/18$

$3\mathrm{.}2,7/7/18$

$4\mathrm{.}5,7/16/18$
