Answer 1

#include <stdio.h>
int main()
{
int bijiao(int x,int y,int z);
int (* p)(int x,int y,int z);
int a,b,c,d;
while(1){
printf("Please input three numbers(a,b,c):");
scanf("%d,%d,%d",&a,&b,&c);
p=bijiao;
d=(* p)(a,b,c);
if(d==0)
{
printf("a>=b>=c:\n");
printf("%d>=%d>=%d\n",a,b,c);
}
else if(d==1)
{
printf("a>=c>b:\n");
printf("%d>=%d>%d\n",a,c,b);
}
else if(d==2)
{
printf("c>a>=b:\n");
printf("%d>%d>=%d\n",c,a,b);
}
else if(d==3)
{
printf("b>a>=c:\n");
printf("%d>%d>=%d\n",b,a,c);
}
else if(d==4)
{
printf("b>=c>a:\n");
printf("%d>=%d>%d\n",b,c,a);
}
else if(d==5)
{
printf("c>b>a:\n");
printf("%d>%d>%d\n",c,b,a);
}
}
}
int bijiao(int x,int y,int z)
{
if(x>=y)
{
if(y>=z) return 0;
if(x>=z && z>y) return 1;
if(z>x) return 2;
}
else
{
if(x>=z) return 3;
if(y>=z && z>x) return 4;
if(z>y) return 5;
}
}
