STUDENT GRADING AND INFORMATION SYSTEM IN C

 A database program that I called Student Grading and Information System in C which uses binay file to add, update, view, and delete the student records.

I am currently accepting programming work, IT projects, school and application development, programming projects, thesis and capstone projects, IT consulting work, computer tutorials, and web development work kindly contact me at the following email address for further details.  If you want to advertise on my website kindly contact me also in my email address also. Thank you.

Divisible By 5 in C++

Divisible By 5 in C++

  In this tutorial, I will show you how to write a program that will input a number and will print “Divisible” if the number is divisible by 5, otherwise print “Not Divisible” using a C++ programming language.
