In C++

Could really use come help with adding a loop to find the array location of each source node. Hint: Use get_value() to compare a node's value to source_name and If the node does not exist, add it to the array using the set_value() function and incrementing n.Save index.

Comment out the output lines in the file input loop in main().1.Test program to verify that your array has been populated:

Sample Run

// add loop here

// Add to array

if(in.good())

{ cout << setw(12) << source_name;

cout << setw(12) << target_name;

cout << setw(4) << distance;

cout << endl;

};

};

// Close file

in.close();

// Display array

for(i=0;i

cout << map[i].get_value() << endl;

}

In the data file each line contains the name of the source node, target node, and distance.The program reads from each line a source node, target node, and distance.
