passing an array to a function to print onto a file, need help

[EDN Admin]

Hello, Im trying to create a program which writes account info onto a separate file after reading the initial data from a separate file. During this the user may withdraw, deposit, check balances, etc. when using the program. Im getting two errors and I am at a loss as how to fix them, Ive tried what it suggests but to no avail, if anyone could point me in the right direction that would be a major help!
