利用数组的方法

解题思路:

注意事项:

参考代码:

#include<iostream>

using namespace std;

#include<vector>

int main() {

int m = 0;

cin >> m;

vector<int> arr;

int start = m * m - (m - 1);

int end = m * m + (m - 1);

for (int i = start; i <= end; i += 2) {

arr.push_back(i);

}

cout << m << "*" << m << "*" << m << "=" << m * m * m << "=";

for (int i = 0; i < m; i++) {

cout << arr[i] ;

if (i != m - 1) {

cout << "+";

}

}

cout << endl;

return 0;

}
