Thread: nid help for my assignment~urgent

program should provide the operations:
• Add a new asset into the array (duplicate entries are not allowed).
• Search for an asset.
• Amend the details of an asset.
• Write-off an asset
• List details of all assets, each on a different line with line numbering.

all i have done, but left the write-off asset i cant do it. i tried many way , i use the amend asset method to make a change but failed. any1 mind too help? here my source file.
