c语言初步经典题10--买玫瑰问题

//匈牙利变量命名法：变量前面的ui表示数据类型
#include <stdio.h>
#include <stdlib.h>
#define PRICE 5
int main()
{
unsigned int uiMoney;//总共的钱
unsigned int uiNofreenum;//不赠送所能买的数量
unsigned int uiFree5;//满5所赠送的
unsigned int uiFree20;//买满20所赠送的

scanf("%u",&uiMoney);
uiNofreenum = uiMoney/PRICE;
uiFree20 = uiNofreenum/20*5;
uiFree5 = (uiNofreenum-(uiNofreenum/20)*20)/5;
printf("%u",uiFree20+uiFree5+uiNofreenum);
return 0;
