i'm supposed to display the list in the last function...can anyone please help?

HI,
Whenever you define a struuct you shuld use struct keyword while declaring variables of that type or else you shuld do a typedef.

//your have to change these
void getData(struct studentType sList[], int NO_OF_STUDENTS);
void calculateGrade(struct studentType sList[], int NO_OF_STUDENTS);
void printResult(const struct studnetType sList[], int NO_OF_STUDENTS);
 
//or change the declaraion like
typedef struct _studnetType
{
//
}studnetType ;
//then you can have the code as it is.

no, it wasn't that at all...i realized i spelled student incorrectly in that function (studnet)...that solved all my errors. haha, i feel so dumb. thanks though!
