【C/C++】數字拆分

將整型數據拆分成單個數值。

#include <iostream>
using namespace std;

int numProcess(int num, int* num_pro)
{
    int diget = 0;
    int num_befor = num;
    int num_after = num;
    while (num_befor != 0)
    {
        num_befor /= 10;
        num_pro[diget] = num_after - num_befor * 10;
        num_after = num_befor;
        diget++;
    }
    return diget;
}

int main()
{
    int num[5] = { 0 };
    int i;
    cin >> i;
    int weishu = numProcess(i, num);
    for (int k = 0; k < weishu; k++)
    {
        cout << num[k] << endl;
    }
    cout << "共輸入：" << weishu << " 個數" << endl;
    return 0;
}
