Question

Prompt the user for the name of an input text file
Read the input text file and display a keyword index for the contents that shows the line number of the first occurrence of each unique word in the file
Display the keyword index

Notes:

You may assume that the input file contains no more than 1000 distinct words
A word is a sequence of non-whitspace characters delimited by whitespace, as per the C convention

Sample Output

Program: Structs
Enter an input file name: input.txt
The input file contains 7 distinct words
alpha, 7
beta, 6
charlie, 5
delta, 4
echo, 3
foxtrot, 2
golf, 1

[done]

Sample input file input.txt:
golf
foxtrot
echo
delta
charlie
beta
alpha

cant figure out whats wrong with it
