I'm programming a student report card with arrays. This is a function that assigns the letter grade according to the numeric value

void SetGradeLetter(int studGrade[], char studGradeLetter[]) {
                        //SIZE is 10 because there should be 10 students
    for (int i = 0; i < SIZE; i  ) {  
        if (studGrade[i] <= 100 && studGrade[i] >= 90) {  
            studGradeLetter[i] = 'A';
        }
        else if (studGrade[i] <= 89 && studGrade[i] >= 80) {
            studGradeLetter[i] = 'B';
        }
        else if (studGrade[i] <= 79 && studGrade[i] >= 70) {
            studGradeLetter[i] = 'C';
        }
        else if (studGrade[i] <= 69 && studGrade[i] >= 60) {
            studGradeLetter[i] = 'D';
        }
        else if (studGrade[i] <= 59 && studGrade[i] >= 0) {
            studGradeLetter[i] = 'F';
        }
    }
}

the list looks something like this

Name       Grade
code: studentname[] << setw << studGrade[] << " " << studGradeLetter[] << endl;
student1    80 B //example
student2    70 C
student3    90 A
student4    100 A
student5    50 F
student6    84 B
student7    91 A
student8    48 F
student9    91 A
student10   61 D

and I'm having trouble with a function that should cout the grades in order and show how many students got each grade.

it should look like this

Grade  Total
A   |   4
B   |   2
C   |   1
D   |   1
F   |   2

I'm confused how should I do the function
