This C program calculate the CGPA if the GPAs of each semseter is Entered. Compile and run this program. This caclculator is based on Jerala University Btech 2008 scheme. This program was done for pure fun, I had a php version but as I formated my system lost it.

Dear Rahul
This program was tested in ubuntu and was compiled with gcc, as such it had no problem and even now I have checked it and it is still showing the output.
i have secured 7.52 and 6.88 in 3rd and 4th semester and 7.22 and 7.28 in 5th and 6th semester in B TECH, CET keala university . what is my % in 2nd and 3rd year. i want the answer immediately, as i have to apply for some exams
the above rogram is based on the formula CGPA=( sum(credits for a semester * gpa of that semester)/total credits of all semsters)
In your case CGPA=(credit of 3rd sem * 7.52 + credit of 4th sem * 6.88)/(credit of 3rd sem + crtedit of 4th sem)
this CGPA *100 should give the % for 2nd year similarly for 3rd year. Its good to confirm with the university.
