Problem 1

Background:
One of the possible usages of graph data structure is to show the relations among the cities in a state. Assume that you are given a state, which consist of TEN cities as shown in the following table:

From City To City Distance
A B 8
A D 2
B C 8
B D 7
B F 9
C G 12
D I 10
E F 7
F G 14
G J 6
H D 1
I E 8

Task:
You are given a file that contains the information shown in the table. The file is named as Input.txt and it is in the following structure:

A
B
C
D
E
F
G
H
I
J
=====
I E 8
G J 6
B F 9
H D 1
F G 14
B D 7
E F 7
A D 2
B C 8
D I 10
A B 8
C G 12

The file basically contains two important sections that are separated by FIVE “=” symbols. The lines before the “=====” are the sets of cities in the state. The lines after the “=====” are the set of relationships among the cities. For instance, I E 8; this basically reflects that we can travel from city I to city E with the distance 8 units.
You are to implement a graph data structure to illustrate the relationships among those cities based on the text file given. You must employ the adjacency list method to implement the graph. You can make use of the STL container

ممنون دوست عزيز.
ولي آيا شما کانورتر c++ به .net را نداريد و يا خود برنامه را به زبان c++؟
