c语言算法问题

Answer 1

#include"stdio.h"
intmain(void)
{
int count, fen1, fen2, fen5, money;

scanf("%d", &money);
count=0;
for(fen5=money/5;fen5>=1;fen5--)
for(fen2=money/2;fen2>=1;fen2--)
for(fen1=money/1;fen1>=1;fen1--)
if(fen5*5+fen2*2+fen1*1==money)
count++;
printf("count = %d\n",count);

return 0;
}

Answer 2

#include"stdio.h"
int main()
{
int a,i;
printf("请输入一个正整数\n");
scanf("%d",&a);
if(a%2==0)
{
printf("偶数:\n");
for(i=0;i<=a/2;i )
printf("]",2*i);
printf("\n");
printf("奇数:\n");
for(i=1;i<a/2;i )
printf("]",2*i-1);
}
else
{
printf("偶数:\n");
for(i=0;i<=(a-1)/2;i )
printf("]",2*i);
printf("\n");
printf("奇数:\n");
for(i=0;i<(a-1)/2;i )
printf("]",2*i 1);
}
return 0;
}
