初学者 希望站长可以让我在此成长 只是些数组 指针 循环

 #include <stdio.h>
#include <stdlib.h>
#include <malloc.h>
#define N 80
main()
{
    int *num;
    num=(int *)malloc(N * sizeof(int));
    if(num == NULL )
    {
        printf("Insufficient memory available.\n" );
        exit(1);
    }
    else
    {
        printf("Memory space allocated.\n");
        printf("please enter some num less than %d int:\n", N);
       scanf("%d",num);
       printf("%d\n", *num);
        free(num);
        num = NULL;
        printf("Memory freed.\n");
    }
    system("pause");
    return 0;
