int iLength=0;
int iValue=iCount;
while(iValue>0){

iLength++;
}
if(iLength){
switch(iLength){
case 0:str="00000000";break;
case 1:str="0000000"+str;break;
case 2:str="000000"+str;break;
case 3:str="00000"+str;break;
case 4:str="0000"+str;break;
case 5:str="000"+str;break;
case 6:str="00"+str;break;

}
}
printf("a: %d\n",iCount);
printf("a: %d\n",(unsigned char*)str.c_str());
printf("b: %d\n",(unsigned char*)tmpstr.c_str());
以上代码输出来是：
a: 4998
a: 4258988
b: 4259012
遂，泪奔之
