Array with input? please help..beginner

scarlet00014 · 09-26-2008, 11:28 PM

I have std input thats says

@ 3 4

This means that I need to put an @ sign at slot 3 in my array, and slot 4. how do I do this using getline? im using ./exe <input as my command line argument, so my file 'input' looks like this

@ 3 4
% 5 12
# 2 17

so obviously i have a 2 dimensional array.. so.. array[i][j] = @ if i = 0 and j = 3.. right?
how do i put this in a loop?

Code:

char buff[BUFSIZ];
while ( fgets( buff, sizeof buff, stdin ) != NULL ) {
}

Reads from the keyboard, or from the file if you use <input on the command line.
