今天是元宵!

    工作半年后,也要学习别人写博客啦!今天准备尝试模拟微信的红包随机金额算法。

#include "stdio.h"
#include "stdlib.h"
#include "time.h"

void EntryPoint(double money,int count){
	double value = money;
	srand((unsigned)time(NULL));
	int max = money * 100;
	for (int index = 1; index  money - 0.1 * (count - index);)
		{
			value = rand() % max + 1;
			value = value / 100;
		}
		money = money - value;
		printf("this is the %d red packet,=%.2f\n",index,value,money);
	}
	printf("this is the %d red packet,=%.2f\n", count, money);
}

int main() {
	double money = 4.88;
	int count = 5;
	EntryPoint(money,count);
	return 0;
}

太久没有写程序了,好吃力啊,但是写成这样貌似不太科学,因为每次红包出来的金额都不是平均的,红包的金额之间差距很大。还需要改善!
