麻烦老师，看一下这段vc++6代码，错在哪儿？

#include<stdio.h>

int main()
{
    int iNumber1=3;
    int iNumber2=3;

    int iResultPreA,iResultLastA;
    int iResultPreD,iResultLastD;

    iResultPreA=++iNumber1;
    iResultLastA=iNumber2++;

    printf("The Addself...\n");
    printf("the iNumber1 is :%d\n",iNumber1);
    printf("the iResultPreA is: $d\n",iResultPreA);
    printf("the iNumber2 is :$d\n",iNumber2);
    printf("the iResultLastA is:%d\n",iResultLastA);

    iNumber1=3;
    iNumber2=3;

    iResultPreD=--iNumber1;
    iResultLastD=iNumber2--;

    printf("The Deleteself...\n")
    printf("the iNumber1 is :%d\n",iNumber1);
    printf("the iResultPreD is :%d\n",iResultPreD);
    printf("the iNumber2 is :%d\n",iNumber2);
    printf("the iResultLastD is:%d\n",iResultLastD);

    return 0;

}
