那请问要如何更改？？？
我也不知道要如何declare variables

那麼可否問一下, 到目前為止以下這部分是你本身寫的嗎?? 要是真的是你寫的那麼應該知道甚麼是 declaration

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#define ESC 27
#define u 117
#define d 100

void UPP();
void DOWN();
int ChangeTime(int);
//creating a GLOBAL integer array of 10 elements

int numArray[]={1,2,3,4,5,6,7,8,9,10};

char key;
int index;
int temp;

int main()
{

      do
      {
            system("cls");
            //display the outlook
            printf("\tUp/Down Number Rotation\n");
            printf("\t=========================\n\n");
            printf("\tEnter [U] for up rotation\n");
            printf("\tEnter [D] for down rotation\n");
            printf("\tTo stop rotation, any key except [U],[D],[ESC]\n\tPress ESC to quit at anytime.\n\n");
            printf("\tHit any key to start\n\n\t");
            key=getch();
            do
            {
               for (index=0; index<10; index++)//rotate
