basic input aouput program

I ma not able to generate code for the following program.can anyone assist me in writing the code
Write a program in C++ that allows the input of names and ages from the key board and stores them , in characters, in a file titled persons.dat. After the input is finished , the program should print out what is in the file as well as the average age.

So break it down into smaller steps
Step 1 - write a program which reads from the k/b and prints to the screen.

At least try and demonstrate how far you can get by yourself, then we can best help you with the next step.

i'm guessing you don't know file I/O too well or something... post what you have so we can see what you know...
