C PR0gramming..

Neeeed 'C' Help.

I need to read in input from the command line argument and open the text file ( 2nd arguement; nums1.txt in this case)
ie:  ./shitprogram nums1.txt

and so what would i be inputting here:
fopen("????","r");

I know that argv[1] = "nums1.txt" but how would i use this as a variable in fopen() ?

Lets play a game of find the least intuitively named function in the C std lib.

I choose wcstombs()
