[Problem]

将十进制数n转换成m进制数 m<=16, n<=100

[Solution]

#include <vector> #include <iostream> using namespace std; char table[16] = {‘0’, ‘1’, ‘2’, ‘3’, ‘4’, ‘5’, ‘6’, ‘7’, ‘8’, ‘9’, ‘A’, ‘B’, ‘C’, ‘D’, ‘E’, ‘F’}; int main(){ int n, m; while(cin >> n >> m){ vector<char> result; while(n >= m){ result.insert(result.begin(), table[n%m]); n /= m; } if(n > 0 || (n == 0 && result.size() == 0)){ result.insert(result.begin(), table[n]); } // output result for(int i = 0; i < result.size(); ++i){ cout << result[i]; } cout << endl; } return 0; }
