用c++代码实现刚刚的那道题

以下是使用C++语言实现刚刚题目的代码示例:
```cpp
#include <iostream>
#include <vector>
using namespace std;
int makeArrayGood(vector<int>& a) {
int sum = 0;
for (int num : a) {
sum += num;
}
if (sum % 2 == 0) {
return 0; // No operations needed
} else {
int operations = 0;
bool found = false;
for (int i = 0; i < a.size(); i++) {
if ((a[i] / 2) % 2 == 1) {
operations = 1;
found = true;
break;
}
}
if (!found) {
operations = 2;
}
return operations;
}
}
int main() {
int n;
cout << "Enter the number of elements in the array: ";
cin >> n;
vector<int> a(n);
cout << "Enter the elements of the array: ";
for (int i = 0; i < n; i++) {
cin >> a[i];
}
int minOperations = makeArrayGood(a);
cout << "The minimum number of operations needed to make the array good is: " << minOperations << endl;
return 0;
}
```
请注意,此示例假定输入的数组 a 中的每个元素都为正整数。它接受用户输入数组的大小和元素,并计算最小操作次数来使数组成为好数组。最后,它将输出所需的最小操作数。
