在2d数组c ++中找到列的总和

Question

如何找到列的总和？我只知道如何找到行和的总和 整体总数

对不起我还是新手大学新生程序员

感谢任何可以帮助我的人！

这是我的代码：

    #include <iostream>
    using namespace std;

    int main()
    {
        int row, column, rowsum=0, total=0, number1=1, number2=1;
        int rowcol[5][5];
        {
            for (row = 0; row < 5; row++)
            {
                for (column = 0; column < 5; column++)
            {
                cout << "Enter employee no." << number1 << " salary: ";
                cin >> rowcol[row][column];
            }
            number1 = number1 + 1;
            }

            for (row = 0; row < 5; row++)
            {
                rowsum = 0;
                for (column = 0; column < 5; column++)
                {
                    rowsum = rowsum + rowcol[row][column];
                }
                cout << "Total salary of employee no." << number2 << ": " << rowsum << endl;
                number2 = number2 + 1;  
            }

            for (row = 0; row < 5; row++) 
            {
                for (column = 0; column < 5; column++)
                {
                    total = total + rowcol[row][column];
                }
            }
            cout << "Total salary of all employees: " << total;
        }
        system("pause>0");  
        return 0;   
    }
