Let's assume a file of FETUD students consisting, for each student, of the following information: Code, Last name, First name, Average. Write an algorithm that allows you to: $1.$ Create the FETUD file $($the number of students is not known in advance$),2.$ Write a function which returns the number of admitted students $($Average$>=10)$ in the FETUD file, $3.$ Create from the FETUD file two files FADM $($admitted file, Average$>=10\mathrm{.}00)$ and FAJR $($adjourned file, Average $<10\mathrm{.}00).$
