Passing pointers to functions within functions URGENT.
May 2, 2015 at 8:03pm UTC
I have a lab due tomorrow, so thanks for a quick reply.
For some reason, my pointer won't cout when it comes to the printInventory function. I printed it in the readFile function, but it wont do the same in the printInventory function. can you check it out?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81

readFile (count, &inventory);

readFile should take count by reference (or by address if you prefer.)
