In the modern education and growing economy and population it heavily relies on advanced computational power. The deployment of the classroom allocation through computational approaches are very limited. Therefore, in this paper we have to design the classroom allocation system along with student subject choice. We implemented the code in C programming language. The programming of the allocation system consists of brute force approach. This approach provides a facility to feed the data of student capacity, Course identification, course name, department, course credit and day. Moreover, the algorithm classify the classroom as final schedule, which consists of both day and department. Further, the administration can schedule the classroom, update and edit the file for efficient classroom management. The scheduled output is displayed in tabular format. This application can be potentially utilized in the management of education. This application document the details and execution, that helps the staff of any Institution to assign classrooms for a given courses. As in most of the institution, handle this allocation process with a manual procedure which involves the coordination with all the departmental representatives and staff from the Administration Office. Usually, the manual procedure like this gives way to various challenges and is inclined to fault. This application takes into attention, the most necessary elements such as the classroom size, course capacity, and preferred block of a department and provide error free classroom allocation facility.
