Input Format

A text file containing city name, country, latitude and longitude is loaded.

This information is stored in the citynaro array.

The input.ce file is as follows.

Output Format

You should write a program that performs the following actions based on the

selected option number

Entering the number $1$ will perform the task of printing the list $($Task $1).$

Entering the number $2$ will perform the task of adding data $($Task $2).$

Entering the number $3$ will perform the task of removing data $($Task $3).$

Entering the number $4$ will perform the task of modifying data $($Task $4).$

Entering the number $5$ will perform the task of sorting data $($Task $5).$

Entering the number $6$ will perform the task of saving file $($Task $6).$

Entering the number $0$ will terminate the program and entering a different

number that is not predefined will perform the error message $($Task $0).$

Example Data

Entering the number $1,$ perform "Print List" Task.

Entering the number $2,$ perform "Add Data" Task.

Sample Input

C$1$ty name: EEP

Country name: EEP$22301$

Latitude value btw $$ to $90$ with N$/$S $($North$/$South$)$: $80N$

Longitutde value btw $0$ to $180$ with $\frac{E}{W}($East$/$west$)$: $98E$

Sample Output Entering the number $3,$ perform "Remove Data" Task.

Sample Input

Enter the city name you want to remove: EEP

Sample Output

Entering the number $4,$ perform "Modify Data" Task.

Sample Input

Enter the city name you want to modify: Seoul

What information are you going to modify?

$($city$,$ country, latitude, $1$ongitude$)$: latitude

Enter new latitude value btw $0$ to $90$ with N$/$S$.$

$45S$

Sample Output

Entering the number $5,$ perform "Sort Data" Task.

Sample Input

Select an option that you want to sort

$($ascending$,$ descending, shuffle$)$: ascending

Which data do you want to sort?

$($c$1$ty$,$ country, latitude, long$1$tude$)$: long$1$tude

Sample Output

Entering the number $6,$ perform "Save File" Task.

Sample Input

Enter the file name: Problem $2($PJT$3\_2.$cpp$)70$pts

Problem statement

For problem $2,$ read an input text from input.$-1$xt$.$ The informations are stored in the

cityInfo arrin $($or citysmfo wector if you can implement it$).$ You should write a program that

performs the following tasks.

Print list

This task is to print in the order stored in the citymifo arriy.

The output must reflect the results of tasks $2$ to $5.$

Failure to run this task's code will result in a score of zero.

Add Data

This task is to store data $($city name, country, latitude, and longitude$)$ using cin

in the citycifo arriny.

If the entered latitude and longitude values are incorrect, set them to "default"

values. $($set the "default" values individually and freely$)$

latitude: floating$-$point number between $[090],$ inclusive, rounded to two

decimal places, direction must be $N$ or $S.$

longitude: floating$-$point number between $[0180],$ inclusive, rounded to two

decimal places, direction must be $E$ or $W.$

Remove Data

This task is to remove the corresponding row to the city name recelved as input.

If there is no matching name, no changes.

Modify Data

This task is to edit data corresponding to the city name received as input.

Firstly, you get the cityzifo related to the city name as input.

Then, you modify one of the values in the city nif. $($city name, country,

latitude, and longitutde$).$

If modifying the latitude and longitude values, check if the conditions are met.

If the latitude and longitude values are incorrect, as in task $2,$ do not modify

the value.

latitude: floating$-$point number between $[090],$ inclusive, rounded to two

decimal places, direction must be $N$ or $S.$

longitude: floating$-$point number between $[0180],$ inclusive, rounded to two

decimal places, direction must be $E$ or $W.$

Sort Data

This task to select one of ascending order, descending order, or shuffle to sort

or shuffle data.

If ascending or descending order is selected.

choose the data to use as the sorting criterion $($city name, country, latitude, or

longitude$).$

Latitude: ascending order with south$)090N(90$ north$),$

descending order with $90N090S.$

Longitude: ascending order with $180W(1800$ west$)0180E(180$ east$),$

descending orther with $180E0180W.$

If shuffle is selected,

randomly shuffle the current list.

You may use the method used in Problem $1$ or any other method.

Save File

This task receives a file name as input and saves the list to a text file.
