    Thus, m & n (rows & columns) are the same.
    Later versions can allow the number of rows and columns to be different. 

    size - the dimension of both matrices.  
    m - the number of rows

大家好，

我正在开发一个C ++应用程序，它将元素加载到10行10列的第一个数组中，并将元素加载到第二个数组中，该数组也是10 x 10，然后将每个数组元素添加到一起并放入它们在一个名为sum的数组中。例如，实际上当你添加矩阵时，你会在下面做这样的事情，但是我的数组比这更复杂。问题是如何使用嵌套for循环将元素加载到我的每个数组中。任何例子都将非常感谢!!!这是我到目前为止的代码。我知道如何在数组中输出元素，但我从未使用for循环将元素加载到数组中。

[1 2 4] + [2 3 7] = [3 5 11]

Answer 1

for (int i=0; i<size; ++i)
{
    for (int j=0; j<size; ++j)
    {
        std::cout << "first[" << i << "][" << j << "]" << std::endl;
        std::cin >> first[i][j];
    }
}

如何使用for循环将元素加载到每个数组中，然后将每个数组的总和输出到sum数组中？
