请教高手,为什么还wa,还有没有测试数据啊#include<stdio.h>
#include<string.h>
void del(char a[100])/*去前导和后导0*/
{
int i=0,j=0,len;
len=strlen(a)-1;
while(a[i]=='0')
i++;
for(j=len;;j--)
{
if(a[j]=='0')
len--;
else
break;
}
a[len+1]='\0';
j=0;
while(a[i])
{
a[j]=a[i];
i++;
j++;
}
a[j]='\0';
}
int s(char a[100],char b[100],int m)/*求和*/
{
int i,t,c=0,len;
len=strlen(b);
for(i=0;b[i];i++)
{
t=a[i]+b[i]-'0'-'0'+c;
if(t>9)
{
t=t-10;
c=1;
}
else
c=0;
a[i]=t+'0';
