一个看像完整的程序，为什么错漏百出

如何输入firstmatrix和secong matrix?

您好象贴错地方了......

去C++教室那边贴看看吧
----------------解决方案--------------------------------------------------------
#include &lt;iostream.h&gt;
----------------解决方案--------------------------------------------------------
#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{
return 0;
}
