元素在二维数组c++中的出现次数

#include <iostream>
using namespace std;

int countOccurrences(int arr[][3], int rows, int cols, int target) {
    int count = 0;
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            if (arr[i][j] == target) {
                count++;
            }
        }
    }
    return count;

int main() {
    int arr[3][3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
    int target = 2;
    int occurrences = countOccurrences(arr, 3, 3, target);
    cout << "The element " << target << " occurs " << occurrences << " times." << endl;
    return 0;
