我正在尝试执行tranpose功能，但无法获得
I am trying to perform the tranpose function but can not get it
我在最终的void函数上有问题，我试图将其调查为我声明为int l的变量行和列总和和toal总和的结果，我对我应该做什么或如何分开计算行或列感到困惑是问题
编写菜单驱动的C 程序，以执行以下操作在二维数组a的大小m x n上。您应该使用用户定义的功能，该功能接受2-D数组A及其大小M和N作为参数。选项是：
要输入元素中m x n的矩阵显示M X N大小的矩阵的元素大小m x n矩阵的所有元素的总和显示大小m x n的矩阵的行总和显示M X N大小的矩阵的列和创建大小n x n
