Command line arguments are passed to int main(int argc, char** argv) as arguments
argc and argv. You should assume that argc is at ebp+8 and argv is at ebp+12.
This code returns the following value from main (in register eax):
1) product of the command line arguments
2) sum of the command line arguments
3) number of characters in the command line arguments
4) how many command line arguments were provided
