[Ｃ++] 雖然已經考完上機

[sb0917 (バカ)]

剛剛把第十二題用傳陣列的方式弄出來了...

#include <iostream>
#include <iomanip>
#include <ctime>
using namespace std;

void fun(int **,int **,int **,int m,int n,int l);

int main()
{
        srand(time(NULL));
    int a[11][11]={0};
        int b[11][11]={0};
        int c[11][11]={0};
        int i,j,k,sum,m,n,l;
        int *ap[11],*bp[11],*cp[11],**A,**B,**C;//真的是超麻煩...

        cout << "Mat.A(MxN),Mat.B(NxL),Please input M,N,L:\n";
        cin >> m >> n >> l;

        cout << endl;
    cout << "Matrix A(" << m << "x" << n << "):\n";
        for(i=0;i<m;i++)
        {
                for(j=0;j<n;j++)
                {
            a[i][j] = rand()%9 + 1;
                        cout << setw(3) << a[i][j];
        }
                cout << endl;
        }

    cout << endl;
        cout << "Matrix B(" << n << "x" << l << "):\n";
        for(i=0;i<n;i++)
        {
                for(j=0;j<l;j++)
                {
            b[i][j] = rand()%9 + 1;
                        cout << setw(3) << b[i][j];
        }
                cout << endl;
        }


    for(i=0;i<11;i++)
    {
        ap[i] = a[i];
        cp[i] = c[i];
        bp[i] = b[i];
    }

    A = ap;
    B = bp;
    C = cp;

    fun(A,B,C,m,n,l);

    cout << endl;
        cout << "Matrix C(" << m << "x" << l << "):\n";
    for(i=0;i<m;i++)
        {
                for(j=0;j<l;j++)
                        cout << setw(4) << c[i][j];
                cout << endl;
        }

        system("pause");
    return 0;
}

void fun(int **a,int **b,int **c,int m,int n,int l)
{
    int sum,i,j,k;

    for(i=0;i<m;i++)
                for(j=0;j<l;j++)
                {
                        sum = 0;
                        for(k=0;k<n;k++)
                                sum += a[i][k]*b[k][j];
                        c[i][j] = sum;
                }

}

發牌程式如果不想設全域變數就只能靠傳雙重指標了...
