SECTION–B

Q. 4

Write a simple program in C/C++ to calculate the marks of each student appearing in this paper. The marks must be identified for each section (A, B,…), question (1,2,…) and part of the question (a, b, etc.). The program must calculate the total marks obtained subject to following conditions. [20] Only five questions are attempted. Student must attempt compulsory question and at least one question from each section. Marks of one question will not be counted if no question is attempted from any one section. Al questions carry equal (20) marks each. All marks are equally divided in question parts (a, b, c,…etc.). There is no negative marking. Student must not get more than maximum marks allotted to the question attempted.
