C語言編程：求壹段發紅包的代碼。（隨機數，能規定紅包總錢數總人數，每個人拿到的錢不為0）

#include<time.h>

#include<stdlib.h>

int?main(void)

{

float?total;

printf("輸入總錢數:\n");

scanf("%f",&total);

int?num;

printf("輸入紅包數量:\n");

scanf("%d",&num);

float?min=0.01;

float?safe_total;

float?money;

int?i;

srand((unsigned)time(NULL));

for(i=1;i<num;i++){

safe_total=(total-(num-i)*min)/(num-1);

money=(float)(rand()%((int)(safe_total*100)))/100+min;

total=total-money;

printf("紅包%2d:?%.2f元，余額：%.2f元\n",i,money,total);

}

printf("紅包%2d:?%.2f元，余額：0.00元\n",num,total);

return?0;

}
