want a Substitutes management system for a school

Usually in my school , a set of 5 teachers are assigned the job of making the substitutes for the absent teachers i.e making sure some other teacher goes in the classes of absent teachers to teach the students and also to make sure that , that teacher's time table is not disturbed i.e the teacher will be assigned that work only if he/she has a free period. So what you have to do is -- to make a program in C++ using file handling and any other features you like to take the input as: 1. Names of all teachers [login to view URL] the attendance of teachers every day [login to view URL] the timetable of all teachers as input from admin Then , check if any teacher has a free period when an absentee teacher would be having a regular period in a class and assign that teacher the absentee teacher's class. Also every teacher shall be linked to their subjects(i.e Maths, Physics, English , Chemistry , Computer Sciences , etc) I'll explain more about the project when I get anybody to agree to make this
