C$++$ code

I need help with this question with C$++$ code please

FastFlight Airlines only flies to a few cities in the United States. Those cities are Charlotte, North

Carolina, Orlando, Florida, Houston, Texas, Denver, Colorado and San Diego, California. Charlotte and

Orlando are in the eastern time zone. Houston is in the central time zone. Denver is in the mountain

time zone and San Diego is in the pacific time zone. There is a one$-$hour difference between each time

zone. For example, when it is $11$:$00$ A$.$M$.$ in Orlando it is $8$:$00$ A$.$M$.$ in San Diego. A diagram that shows

Fast Flights various flights and the flight times for each flight is shown below:

Write a program to determine the arrival time for each of their flights that accounts for changing time

zones.

Input is from a datafile where a number $N$ represents the number of flights. $N$ lines of data each

containing the departure city, departure time and destination city. A$.$M$.$ and P$.$M$.$ will always be

capitalized and contain periods. Consider midnight as $12$:$00$ A$.$M$.$ and noon as $12$:$00$ P$.$M$.$ Output to the

screen, the departure city and local departure time followed by the destination city and the local arrival

time for each flight listed in the input data, properly labeled. Times should be formatted such that single

digit hours are shown without a leading zero, but single digit minutes should be shown with a leading

zero. A graph data structure must be used. Let the user enter the file name from the keyboard. Refer to

the sample output below.

Sample File:

$3$

Houston $6$:$00$ A$.$M$.$ Orlando

Orlando $1$:$25$ P$.$M$.$ Charlotte

Charlotte $7$:$30$ A$.$M$.$ San Diego

Sample Run:

Enter file name: airtimes.txt

Flight $1$: Houston $6$:$00$ A$.$M$.$ Orlando $9$:$01$ A$.$M$.$

Flight $2$: Orlando $1$:$25$ P$.$M$.$ Charlotte $2$:$54$ P$.$M$.$

Flight $3$: Charlotte $7$:$30$ A$.$M$.$ San Diego $8$:$53$ A$.$M$.$
