【问题描述】:
我正在尝试使用 struct 对两个矩阵求和,但它不起作用。
如果这段代码可以优化,请告诉我:D
编译:
g++ -O2 -Wall program.cpp -o program
输出:
在 /usr/include/c++/4.8/iostream:39:0 包含的文件中, 来自 Proy3.cpp:2: /usr/include/c++/4.8/ostream:548:5: 注意:模板 std::basic_ostream& std::operator
代码:
# include < cstdio >
# include < iostream >
typedef struct Matrix
{
int row, column;
int x[20][20];
};
Matrix M1,M2;
使用命名空间标准;
int main() {
cout << "Insert size rows: Mat[a]";
cin >> M1.row);
cout << "Insert size of columns Mat[a]";
cin >> M1.column;
cout << "Insert size of rows Mat[b]";
cin >> M2.row;
cout << "Insert size of columns Mat[b]";
cin >> M2.column;
int i, j;
// Matrix x
for(i = 0; i <= M1.row; i++)
{
for(j = 0; j <= M1.column; j++)
{
cout << "Insert number for matrix X : \n";
cin >> M1.x[i][j]
}
}
// Matrix y
for(i = 0; i <= M2.row; i++)
{
for(j = 0; j <= M2.column; j++)
{
cout << "Insert number for matrix Y : \n";
cin << M2.x[i][j];
}
}
// Matrix X + Matrix Y
for(i = 0; i <= M1.row; i++)
{
for(j = 0; j < M1.column; j++)
{
cout <<"The sum of " << M1.x[i][j] << " + " << M2.x[i][j] << " = " << M1.x[i][j] + M2.x[i][j] << endl;
}
}
return 0;
}
