const automatic array must be fully initialized如何修改错误，还有下面的主函数以及平均函数的伪代码如何写

#include<stdio.h>
#define STUDENTS 3
#define EXAMS 4

double minimum(const int setOfGrades[],int tests);
int main(void)
{
int student;
const int studentGrades[STUDENTS][EXAMS]=
{{77,68,86,73},
{96,87,89.78},
{70,90,86,81}};
for(student=0;student<STUDENTS;student++){
printf("The minimum grade for student %d is %.2f\n",
student,minimum(studentGrades[student],EXAMS));
}
getchar();
return 0;
}
double minimum(const int setOfGrades[],int tests)
{
int i;
int min=setOfGrades[0];

for(i=0;i<tests;i++){
    if(min>setOfGrades[i])
        min=setOfGrades[i];
}

return min;
}

这里是逗号，不然少初始化了一个
