C++找出两个数组中不相同的数

1.定义两个结构体，对每个结构体定义一个vector，存放相应的内容，找出两个vector中不同的数据点

int eql1 = 0;int eql2 = 0;std::vector<RecvInfo> m_RecvNew;std::vector<Info> m_SaveRecv;for (int i = 0; i < m_SaveRecv.size(); i++){for (int j = 0; j < m_RecvNew.size(); j++){if ((strcmp(m_SaveRecv[i].cIdcode, m_RecvNew[j].cIdcode) == 0) && (strcmp(m_SaveRecv[i].cDev_no, m_RecvNew[j].cDev_no) == 0)){eql1 = 1;break;}else{eql1 = 0;}}if (eql1 == 1){continue;}printf("[%s] 只有m_SaveRecv容器中有\n", m_SaveRecv[i].cDev_no);}for (int m = 0; m < m_RecvNew.size(); m++){for (int k = 0; k < m_SaveRecv.size(); k++){if ((strcmp(m_SaveRecv[k].cIdcode, m_RecvNew[m].cIdcode) == 0) && (strcmp(m_SaveRecv[k].cDev_no, m_RecvNew[m].cDev_no) == 0)){eql2 = 1;break;}else{eql2 = 0;}}if (eql2 == 1){continue;}printf("[%s] 只有m_RecvNew容器中有\n", m_SaveRecv[m].cDev_no);}
