Array in C Language Programs

ℚ. 1 The examination committee of the university has decided to give 5 grace marks to every student of a class. Assume that there are list of students in the class and their marks are stored in a list called marksList. Write a program that adds the grace marks to every entry in the marksList.

/* This program adds grace marks to all elements of a list of marks */
