C冲突类型错误

Question

void ListRecord(struct Product* prd)
{
    int i;
    system("cls");
    printf("%10s%20s%20s","BarcodeNumber","Name","Quantity","Price");

    for(i=0;i<30;i++)
    {
        if(prd[i].isFull=='E')
        {
            printf("\n%10s%20s%20s",prd[i].barcodeNumber,prd[i].name,prd[i].quantity,prd[i].price);
        }
    }
    getch();
}

这个方法给出了ListRecord方法的冲突错误，但我没有得到错误的东西？
