If you mean "this doesn't compile, why not?" then look at the error message.
Which in this case will be along the lines of "expression must be a modifiable lvalue" and which will point at the two lines:
status[j]="Active";
...
status[j]="Dismiss";
What the error means is that what you are trying to assign isn't valid: you are trying to assign a pointer to a constant string to a pointer to a normal string - which means you could later try to alter a constant, which would lead to all sorts of nasties...
Instead, try this:
const char *status[10];
and
fprintf(fptrOutPut,"%d%d%s\n",&ID_Student[j], &Average[j], status[j]);
Leave the rest of your code alone.
Try that and see what happens!
