Format C Command Prompt

i've never knew how to use command line arguments since the first source code i used to edit(and from i learned basics of c++) was using a config file to 'read' user input data on program startup and not command line arguments.

now my question, what's the difference between using command line arguments and creating a special designed class to read a config file (config.cfg) looking like this:

i know that on the first thought, the cfg option is far more complicated and timeconsuming, but almost every program needs a config file to read the default values for the data it needs

i ask this cuz i'm not sure if it's worth learning to use command line arguments or not

How To Run Dev C Command Prompt Argc Argv In C

Command line arguments are very simple and worth knowing. For example:

The arguments correspond exactly to what's typed into the console, which means there's a caveat that args[0] will be the program name in some form[*]. That's really all there is to it. You can quibble about the nuances of the argc and argv parameters, but there's little point in doing so, in my opinion. ;)

[*] 'Some form' means it could be an empty string if the program name isn't available, or it could be a full path, or a relative path, or even just the executable name (to list some common results).
