部分A+B

    正整数A的“D_A（为1位整数）部分”定义为由A中所有D_A组成的新整数P_A。例如：给定A = 3862767，D_A = 6，则A的“6部分”P_A是66，因为A中有2个6。现给定A、D_A、B、D_B，请编写程序计算P_A + P_B。

   

#include<iostream>#include<string>using namespace std;int sumAandB(string strA, int DA, string strB, int DB){int sumA = 0;int sumB = 0;for (int i = 0; i < strA.size(); i++){char tmp = strA[i];if ((tmp - '0') == DA)sumA = sumA * 10 + (tmp - '0');}for (int i = 0; i < strB.size(); i++){char tmp = strB[i];if ((tmp - '0') == DB)sumB = sumB * 10 + (tmp - '0');}return sumA + sumB;}int main(){string strA, strB;int DA, DB;cin >> strA >> DA >> strB >> DB;cout << sumAandB(strA, DA, strB, DB) << endl;cin.get();cin.get();}
