简单加密

输入两个数

#include<iostream> #include<string> using namespace std; int main() { int data, key; cin >> data; cin >> key; string str = to_string(data); int size = str.size(); string res(size,-1);//必须要初始化，否则下面会报错 for (int i = 0; i < size; i++) { res[i]=str[(i+key)%size]; } int result = stoi(res); cout << result; return 0; };
