谁帮帮我啊

输出矩阵中行、列的累加和

给你个实例代码，但我建议你自己好好做作，对你将来有好处 #include #include #include using namespace std; /* * */ int main(int argc, char** argv) { int iArray[3][5]; int iSumLine[3]; int iSumCol[5]; int iTotal; for (int i = 0; i > iArray[i][j]; iSumLine[i] += iArray[i][j]; iSumCol[j] += iArray[i][j]; } } std::cout << "矩阵数据如下："...全部
