数组中元素出现的次数

#include <iostream>using namespace std;void show(int* A, int n) {for (int i = 0; i < n; i++) {cout << A[i] << ' ';}}void count(int* A, int n) {int count[12] = {0};for (int i = 0; i < n; i++) {count[A[i]]++;}show(count,n);}int main(){int A[] = {6,2,4,1,2,5,6,2,4,1,2,5};count(A,12);    return 0;}
