哪错了???
#include<bits/stdc++.h>
using namespace std;
#define maxx 1145
char sa[maxx],sb[maxx];
int la,lb,lc, jw,f,w,a[maxx],b[maxx],c[maxx*maxx];
int main()
{
scanf("%s",sa);
scanf("%s",sb);
la=strlen(sa);
lb=strlen(sb);
for (int i=0;i<la;i++)
{
a[la-i-1]=sa[i]-'0';
}
for (int i=0;i<lb;i++)
{
b[lb-i-1]=sb[i]-'0';
}
jw=0;
for (int i=0;i<la;i++)
{
for (int j=0;j<lb;j++)
{
f=a[i]*b[j];
jw=f/10;
f%=10;
w=i+j;
c[w]=c[w]+f;
c[w+1]=c[w+1]+jw+c[w]/10;
c[w]%=10;
}
}
lc=la+lb;
while(c[lc]==0)lc--;
if(lc<0)
{
printf("0");
}
else
for(int i=lc;i>=0;i--)
{
printf("%d",c[i]);
}
return 0;
}

叫你臭,范围是10^2000,你只开到了10^1145。验证码88t8祭

找到问题了: 把1145改成5000就过了。 嘻嘻!
