poj2572 -- Hard to Believe, but True!

先把字符串翻转过来，再通过sscanf函数的处理，获取A,B,C的值，再做比较，需要注意的是当输入 0+0=0 输出True 然后结束

 1 #include <iostream>

 3 using namespace std;
 4 char data[30];
 5 int main()
 6 {
 7     while (true)

10         if (strcmp(data, "0+0=0") == 0)

12             cout << "True\n";

18             int t = data[i];
19             data[i] = data[len-i-1];
