Simple, I will leave how to make a linked list to you, it's really simple.If you dont have any info on that look to
http://www.google.com/.
int main(int args,char **argv)
{
}
This is what the main funtion should look like if you want to accept commandline parameters.Then getting hold of the parameters is as easy as pie (or a 2 dimentional char array

)
The int variable args holds the number of parameters passed to your program
The char array hold the actual parameters
Look here to see how to display all the parameters
for(int i=0;i<args;i++)
{
cout<<"Arg No ["<<(i+1)<<"] = "<<argv[i];
}
That will show you all the parameters passed via the commandline.Also the first parameter (i.e argv[0] ) is always the full path to your exe.
Helps?
