HELP:Data Files

[jack999]

there is a problm in this programmebut i dont know what is itquestionWrite a C-Program that does the following• Read integer numbers from a file inp.dat• Calculate the sum, average, and multiplicand of even numbers and store the result and the even numbers in output file out1.dat• Calculate the sum, average, and multiplicand of odd numbers and stored the result and the odd numbers in output file out2.dat

Ugh! There's no way on earth anyone is going to even try to look at that code - try to format it properly. the very least you can do is not have it all on one continuous line.
