i am working on a program that reads in a text file that the user inputs, creates a text file that the user inputs, names the text file that the user wants, and then sorts the text file sorting words above the user entered in threshold and displays the words and how many times it was found to the output file the user specify’s. i have most of the code finished but im getting a compiler error heres the sample output, error and code
sample output
Enter name of input command file; press return.
history.in
Enter name of output file; press return.
history.out
Enter name of test run; press return.
sample
Enter the minimum size word to be considered.
5
Sample results (found in user specified output file):
sample
abacus 4
abstract 1
adding 1
addition 2
advances 1
after 3
where the word is the word found in the text file, and the number next to it is how many times it was found.
The compiler errors are:
C:\Users\kevin jack\Desktop\prog-4>g++ -o try main.cpp

i have no idea what this means if anyone knows please inform me here is my code

what i was trying to overload the == and > operator. i am stating it in class StrType and defining it just below it but im not sure if im defining it correctly or even in the right spot! any help would be greatly appreciated
