reStructure of code; include 2 void functions

xiikryssiix (27)
does anyone have any advice? i created a program and it works fine.

my teacher, however, is asking me to have my INPUT and OUTPUT to be subprograms such as the VOID function.

i guess my algorithmn has to be..
// struct
// void for inputs
// void for printing
// my main

i have no idea how to go about on doing that.
ive created programs with void functions before, but its different, a lot different.
i tried making this program into a void, but i got a whole lot of errors.

anyone have any ideas or pointers? thanks

[edit] fixed the function call, I was attempting to multitask at the time >_< [/edit]

You are quite on track in logically splitting the functions.
Get the compilation errors away - do read up the c++ manual to know how to 'call' the functions.
You must be getting closer
