10 automatically i want to have 10 student record and 10 subject...PLS HELP ON THIS...what statemement should i use..
#include <stdio.h>
int main()
{
int count = 0;
char letter_grade = 'x';
int a = 0, b = 0, c = 0, d = 0, e = 0;
int student_ID = 1;
double test1 = 0.0, test2 = 0.0, final_test = 0.0, semester_average = 0.0, class_average = 0.0;
do
{
printf("Enter student ID, 0 to terminate: ");
scanf("%d", &student_ID);
if(student_ID != 0)
{
printf("Enter score #1: ");
scanf("%lf", &test1);
printf("Enter score #2: ");
scanf("%lf", &test2);
printf("Enter score #3: ");
scanf("%lf", &final_test);
printf("%d have the following scores: %lf, %lf and %lf\n", student_ID, test1, test2, final_test);
semester_average = (0.20*test1) + (0.30*test2) + (0.50*final_test);
printf("The semester average score for %d is %lf\n", student_ID, semester_average);
if(semester_average >= 80)
{ letter_grade = 'A'; a++; }
else if (semester_average >= 65)
{ letter_grade = 'B'; b++; }
else if (semester_average >= 50)
{ letter_grade = 'C'; c++; }
else if (semester_average >= 40)
{ letter_grade = 'D'; d++; }
else if(semester_average >= 0)
{ letter_grade = 'E'; e++; }
printf("The grade for %d is %c\n", student_ID, letter_grade);
count++;
printf("Student #: %d\n", count);
}
}while(student_ID != 0);
printf("\nTotal number of student: %d\n", count);
