Thread: Help showing in array

I'm trying to get it so i have two functions. In one function I am declaring each address in the array and in the other function I am showing each "grade" that was entered. I want the second part to show the array like so:

Position_____Grade
1 (Grade)
2 (Grade)
3 (grade)
etc.

Code:

#include<stdio.h>
#include<stdlib.h>
#include<ctype.h>
#include<string.h>


#define TRUE 1
#define FALSE 0

int getgrades(int *grades);
int menu(void);
void showgrades(int *grades);


main()
{
      int grades[100];
      
      int key, more = TRUE;
      do
     {
           key = menu();
           switch(key)
           {
                case 1: getgrades(grades); break;
                case 2: showgrades(grades); break;
                case 3: changegrades(); break;
                case 4: findgrades(); break;
                case 5: more = quit(); break;
                default: printf("\nError in selection. Press Enter to Continue\a");
                getchar();
           }
     }
while(more);
return 0;
}


int menu()
{
     system("cls");
     int selection;

     printf("1 = Get Grades\n");
     printf("2 = Show Grades\n");
     printf("3 = Change Grades\n");
     printf("4 = Find Grades\n");
     printf("5 = Quit\n");

     /*For user selection*/
     printf("\n\nEnter your selection here: ");
     scanf("%d%*c", &selection);

     return(selection);
}

int getgrades(int *grades)
{
    int x;
     system("cls");
     printf("Enter Grades\n\n");

     do
     {
          printf("Enter Grade or Press 0 to Exit:");
          scanf("%d%*c", grades);
     }
     while(*grades > 0);
}



void showgrades(int *grades)
{
system("cls");
int i;
     
     printf("Inputed Grades");
     printf("\n\nPosition_______Grade\n");
     for(i=0; i<20; i++)
     {
     printf("%d%18.0lf\n", i+1, grades);
}
getchar();
}


int quit()
{
printf("\nPress Enter to Continue");
getchar();
return 0;
}
