随便输入四个整数，输出按从大到小输出
用if-else-if语句

#include<stdio.h>
int main(){
int a,b,c,d,e;//e用来交换
scanf("%d%d%d%d",&a,&b,&c,&d);
if(a<=b){e=a;a=b;b=e;}//此时a>b
if(a<=c){e=a;a=c;c=e;}//此时a>c
if(a<=d){e=a;a=d;d=e;}//此时a>d,此时a最大
if(b<=c){e=b;b=c;c=e;}//此时b>c
if(b<=d){e=b;b=d;d=e;}//此时b>d,此时b第二
if(c<=d){e=c;c=d;d=e;}//此时c>d
printf("%d %d %d %d",a,b,c,d);
return 0;
}
