I need assistance fixing a program written in C++. It is supposed to open a file called "students.txt," which contains the name of 5 students, who each have 6 grade scores. It extracts the information from the file to create averages for each student. Each student is assigned a letter grade based on their averages. The student's name, letter grade, and average score is supposed to be written onto a new file called "studentsresults.txt" and displayed on the output monitor with cout. However when I run the program, I get weird values in both the created file and the output monitor, as seen in the image below. I wanted to know what is the issue and how to fix it. Here's the program: /* write a program to open a data file called "student.txt" which contains name of at least 5 students and 6 grades each. calculate average grade and letter grade of each and print them into file.(to another file)*/ #include #include using namespace std; int main() { ifstream in_stream; ofstream out_stream; char student_name[5][20]; int test_grades[6]; int i; int j; double average_grade = 0.0; char letter_grade; double total = 0.0; in_stream.open("students.txt"); out_stream.open("studentresults.txt"); for (i = 0; i < 5; i++) { in_stream >> student_name[i]; cout << i << " " << student_name[i] << endl; for (j = 0; j < 6; j++) { in_stream >> test_grades[j]; cout << i << " " << j << " " << test_grades[j] << endl; average_grade = test_grades[j] + average_grade; } average_grade = average_grade / 6; if (average_grade >= 90) { letter_grade = 'A'; } else if (average_grade >= 80) { letter_grade = 'B'; } else if (average_grade >= 70) { letter_grade = 'C'; } else if (average_grade >= 60) { letter_grade = 'D'; } else { letter_grade = 'F'; } cout << "Student: " << student_name[i] << "\tLetter Grade : " << letter_grade << "\tAverage grade:"; cout << average_grade << endl; out_stream << "Student: " << student_name << "\tLetter Grade : " << letter_grade << "\tAverage: " << average_grade << endl; } in_stream.close(); out_stream.close(); return 0; }
