decimal system

HDU 2007-6 Programming Contest

这个是数字转换的问题

写的有点麻烦，请见谅

#include<stdio.h>
#include <iostream>
#include <math.h>
using namespace std;
int main()
{int n;char str[1000], ch[20], num[1000];while (scanf_s("%d", &n) != EOF){int sum = 0;for (int i = 0; i < n; i++){str[0] = '\0';ch[0] = '\0';num[0] = '\0';cin >> str;int length = strlen(str);int startIndex = -1, index = -1;for (int j = 0; j < length - 1; j++){if (str[j] == '('){startIndex = j + 1;num[j] = '\0';}if (startIndex != -1){index++;if (str[j + 1] == ')'){ch[index] = '\0';break;}ch[index] = str[j + 1];}else{num[j] = str[j];}}int lengthNum = strlen(num);int lengthCh = strlen(ch);int quan = 0;for (int q = 0; q < lengthCh; q++){quan += (ch[q] - 48) * (int)pow(10, lengthCh - q - 1);}for (int p = 0; p < lengthNum; p++){sum += (num[p] - 48) * (int)pow(quan, lengthNum - p - 1);}}cout << sum << endl;}return 0;
