Code won't open file, and also I think there is a math problem in result. Criteria and format of code is in comments.

/* Cameron Christensen

[50 pts] Write a C++ program that reads the following student input data (student.dat) into an array of Student c-struct objects. Provide a function in the program that can calculate the students final grade based on the following criteria:

The format of the file is as follows: //STUDENT_NAME //LAB1 LAB2 LAB3 LAB4

Student.dat = Joe Doe 90.8 89.5 67 89.2 99.0 100.0 Susan F. Smith 95.5 94.0 78.5 90 87.5 57 Sam Grover 78 100.0 79.5 69.4 90.0 88.5 Diane C. Phelps 100 78.0 56.0 69 94.0 78 John Franklin 65 87.0 67.0 96 49.0 87 Derrick Myers 89.8 98.5 76 89.2 93.0 100.0
