Hello, I am having trouble understanding why I'm getting these errors.

a4.c:106: error: expected expression before ‘int’

a4.c:106: error: too few arguments to function ‘ass_average’

a4.c:109: error: expected expression before ‘int’

a4.c:109: error: too few arguments to function ‘ass_min’

a4.c:112: error: expected expression before ‘int’

a4.c:112: error: too few arguments to function ‘ass_max’

The error happens here:

```
for (j=0; j<num_assignments; j++)
101 {
102 printf("==============\n");
103 printf("Ass # %d stats\n", j);
104 printf("==============\n");
105
106 avg = ass_average(int num_students, int j);
107 printf(" avg = %f\n", avg);
108
109 min = ass_min(int num_students, int j);
110 printf(" min = %d\n", min);
111
112 max = ass_max(int num_students, int j);
113 printf(" max = %d\n", max);
114 }
```

The function prototypes are defined here:

```
50 int main (int argc, char *argv[])
51 {
52 double ass_average(int num_students, int j);
53 double ass_min(int num_students, int j);
54 double ass_max(int num_students, int j);
```

And an example of one of the functions I am calling:

```
22 double ass_min(int num_students, int j)
23 {
24 int i=0;
25 double current_min=100;
26
27 for (i=0; i<num_students; i++);
28 {
29 if (grades[i][j] < current_min)
30 current_min = grades[i][j];
31 }
32
33 return current_min;
34 }
```

Do you see anything wrong with this? I've spent a very long time trying to fix it with no luck, I'd greatly appreciate some more experienced insight.

Hopefully I can return the favour one day!
