Answer to Question #256704 in C++ for Dion Martins

Question

Write an algorithm that will accept the following for 100 students: The students’ name (studName) and 3 test marks (marks), as well as one exam mark (examMark). The program must calculate the final mark (finMark) for every student. The final mark comprises of 50% of the exam mark added to 50% of the average (agv) of the 3 tests. Display the final mark for every student.
