wa啊,老是wa,用的字符串,跟用fun的对过了。不知道怎么还是wa,贴代码求助#include<stdio.h>
#include<string.h>
int main()
{
int n,lb,i,j,k,sa,sb;
char a[20],b[20];
scanf("%d",&n);
while(n--){
scanf("%s%s",a,b);
sa=sb=0;
while(a[sa]=='0')
sa++;
while(b[sb]=='0')
sb++;
for(i=strlen(a);i<20;i++)
a[i]='0';
lb=strlen(b);
for(i=sb,j=sa;i<lb;i++,j++){
a[j]+=b[i]-'0';
if(a[j]>'9'){
a[j]-=10;
a[j+1]++;
}
}
i=0;
while(a[i]=='0')
i++;
j=19;
while(a[j]=='0')
j--;
for(k=i;k<=j;k++)
printf("%c",a[k]);
printf("\n");
}
return 0;
}
