知道原因了...还是怪自己粗心In Reply To:贴代码了 Posted by:qiqilrq at 2007-05-09 20:02:15 #include <stdio.h>
#include <string.h>
int F[3]={9, 3 ,7};
char id[9];
int sum;
int main()
{
int i, j, T, que, len;scanf("%d", &T);
for(i=1; i<=T; i++){
scanf("%s", id);
len=strlen(id);
sum=0;
for(j=0; j<len; j++) {
if(id[j]=='?') que=j;
else sum+=(int)(id[j]-'0') * F[((len-j-1)%3)];
}
sum%=10;
sum=10-sum;//~~~~~~~~~~~~~~~~~~~~此处sum可能为10!
for(j=0; j<10; j++)
if( (j*F[((len-que-1)%3)])%10 == sum ) break;
id[que]=(char)('0'+j);
printf("Scenario #%d:\n%s\n\n", i, id);
