Hello, I needed some help with this C++ assignment:

Program Challenge 7 Page 1120

Word Index

Write a program that reads the contents of a text file. The program should create a map in which the

keys value pairs are described as follows:

Key The keys are the individual vords found in the file.

Values Each value is a set that contains the line numbers in the file where the word (the key) is

found.

For example, suppose the word robot is found in line 7, 18, 94 and 138. The map would contain an

element in which the key was the string robot, and the value was a set containing the numbers 7, 18,

94, and 138.

Once the map is built the program should create another text file, known as a word index, listing the

contents of the map. The word index file should contain an alphabetical listing of the words that are

stored as keys in the map, along with the line numbers where the words appear in the original file.

inFile.open("First.txt", fstream::in);

if (inFile.is_open())

{

inFile >> temp;

}

else

cerr << "File opennig failure";

return 0;

bool openFile(ifstream &filename)

//testB = (getline(filename, temp));

if (filename)

bool buildMap(map> &First)

string trim(string &str1)
