二维数组。

#include <iostream>
using namespace std;

int main() {
    int m, n;
    cin >> m >> n;
    int arr_1[m][n];
    int arr_2[m][n];
    int similar = 0;
    double rate = 0.0;

    for (int i = 0; i < m; i++) {
        for (int j = 0; j < n; j++) {
            cin >> arr_1[i][j];
        }
    }

    for (int i = 0; i < m; i++) {
        for (int j = 0; j < n; j++) {
            cin >> arr_2[i][j];
            if (arr_1[i][j] == arr_2[i][j]) {
                similar++;
            }
        }
    }

    rate = double(similar) / (m * m);

    printf("%.2f", rate * 100);

    return 0;
