I need to make a program that reads lines of text from a file using the ifstream getline() method, tokenizes the lines into words ("tokens") using strtok(), and keeps statistics on the data in the file. Your input and output file names will be supplied to your program on the command line, which you will access using argc and argv[].

I am mostly confused on how to use argc and argv[] command line

the text file contains:

the quick brown fox jumps over the lazy dog.

now is the time for all good men to come to the aid of their party.

all i want for christmas is my two front teeth.
