Write a program and declare an array called “Exam” with 100 integers. Hence, ask a lecturer to enter the number of students in a class along with each student’s mark that should be stored in the array (use a variable n to know the number of students). The program should then calculate and display: a) the average (float) and the highest and lowest marks of the class, b) the number of grades A, B, C, D and F, according to the following table.

int Exam[99];  //each individual grade
int students;  //number of students
int A=0;  // number of students with A's, B's and so forth
int B=0;
int C=0;
int D=0;
int F=0;


int main(){
    cout "how many students in the class (less than 100)";
    cin >> students

    if(students>100)
        cout "reject";  //make sure you handle invalid user inputs this isn't complete

    cout "enter your marks";
    for(i=0,i<students;i++){
        cout << "mark? " << "(" cout i+1 << cout " student)"
        cin >> Exam[i]
        if(grade is a)
            A++
        if(grade is b)
            B++

        if(grade is c)
            C++

        if(grade is d)
            D++

        if(grade is f)
            F++


    }

    cout "display a b c d e f" cout A << count << B

}
