欧美式计数

给定两个整数A和B，其表示形式是：从个位开始，每三位数用逗号","隔开。 现在请计算A+B的结果，并以正常形式输出。

int fun233(char a[]){int alen = strlen(a), sum = 0;for (int i = 0; i < alen; ++i){if (a[i] == ',' || a[i] == '-')continue;else{sum = sum * 10 + (a[i] - '0');}}if (a[0] == '-')sum = sum*-1;return sum;}void slove(){char a[100], b[100];int aa, bb;while (~scanf("%s %s",a,b)){aa = fun233(a);bb = fun233(b);printf("%d\n", aa + bb);}}
