如果一次买的数量等于50套呢？#include <stdio.h>
int small(int a,int b)
{
if(a>b)
a=b
return a
}
int main()
{
int tops,pants,temp,sum=0
scanf("%d%d",&tops,&pants)
if(tops==pants)
{
if(tops>50)
sum=tops*80
else
sum=tops*90
}
else
{
temp=small(tops,pants)
if(temp>50)
sum=temp*80
else if(temp<50)
sum=temp*90
if(tops>pants)
sum+=(tops-pants)*60
else if(tops<pants)
sum+=(pants-tops)*45
}
printf("%d\n",sum)
return 0
}
显然需要9天，程序如下：#include <stdio.h>
int main()
{
int i=0
double s=0.0
while(1)
{
s+=1.5
if(s>=10) break
else s -=0.5
i++
}
printf("%dday\n",i)
return 0
}
