Welcome to the forum, mikel360 
You need to put together a start for your program, and then we can assist in some concrete way.
You'll need a menu. Something like this function, but with different options and such, of course.
Same basic logic. Main() calls menu(), menu calls everything else (or close to it).
Code:
int menu (void)
{
double avg_score; .
int choice, scores[SIZE], hi_score, lo_score;
get_score(scores);
do {
printf("\nMENU:");
printf("\nMenu option one 1");
printf("\nMenu option two 2");
printf("\nMenu option three 3");
printf("\nQUIT enter 4");
printf("\nEnter your choice: ");
scanf("%d", &choice);
(void) getchar(); //clean the input of newline char
switch (choice) {
case 1: //your code might call many other functions here
break;
case 2: //to handle all these possible choices
break;
case 3: //your code here
break;
case 4: //your code here
break;
default:
printf("Error! Try again please\n");
}
}while(choice != 4);
return 0; //or (0)
}
