设计佣金问题的程序
commission方法是用来计算销售佣金的需求,手机配件的销售商,手机配件有耳机(headphone)、手机壳(Mobile phone shell)、手机贴膜(Cellphone screen protector)三个部件,每个部件单价为:耳机80元,手机壳10元,手机贴膜8元,每月月末向制造商报告销量,制造商根据销量给销售商佣金。如果销售额不足1000元按10%提取佣金,1000-1800元部分按15%提取佣金,超过1800元部分按20%提取佣金。
程序要求:
1)先显示“请分别输入三种手机配件的销售情况:”
2)不满足条件,返回:“输入数量不满足要求”,返回重新输入;
3)条件均满足, 则返回佣金额。返回等待输入。
float commission (int headphone, int shell, int protector)
#include "stdafx.h" #include "iostream" using namespace std; float commission(int headphone, int shell, int protector) { float paymoney; int total = headphone * 80 + shell * 10 + protector * 8; if (total < 1000) { paymoney = total*0.1; cout << "佣金为:" << paymoney; } else if (total >= 1000 && total <=1800) { paymoney = (total - 1000)*0.15 + 100; cout << "佣金为:" << paymoney; } else if (total>1800) { paymoney = (total - 1800)*0.2 + 220; cout << "佣金为:" << paymoney; } return paymoney; } bool check(char *str)//判断是否为数字字符 { int i; for (i = 0; i < strlen(str); i++) if (str[i] < '0' || str[i] > '9') return false; return true; } int change(char *str)//数字字符转为整形 { int len = strlen(str); int h = 0; for (int i = 0; i < len; i++) { str[i] = str[i] - '0'; } for (int i = 0; i < len; i++) { h = h * 10 + str[i]; } return h; } int _tmain(int argc, _TCHAR* argv[]) { char str1[30]; char str2[30]; char str3[30]; int headphone, shell, protector; while(1) { cout << "请分别输入三种手机配件的销售情况:" << endl; cin >> str1 >> str2 >> str3; if (check(str1) && check(str2) && check(str3)) { headphone = change(str1); shell = change(str2); protector = change(str3); commission(headphone, shell, protector); } else { cout << "输入数量不满足要求,返回重新输入"; } system("pause"); } }
