程序如下：include<stdio.h>main(){intx,b0,b1,b2,s;printf("inputx:");scanf("%d",&x);b2=x/100;b1=(x-b2*100)/10;b0=x%10;s=b0*100+b1*10+b2;printf("s=%d\n",s);}...

System.out.println(reverse(123));}}输出结果：1、0403203212、321

C语言输入一个正整数n,将其逆序输出：include<stdio.h>include<stdlib.h>intmain(){inta;while(scanf("%d",&a)!=EOF){while(a>0){printf("%d",a%10);a=a/10;}printf("\n");}return0...

printf("\n倒序输出结果：%d%d%d",c,b,a);getch();}三位数除以100那么商就是三位数的百位上数字，三位数除以10的商再除以10的余数就是三位数的十位上的数字，三位数除以10的余数就是三位数个位上的数字。

代码如下：include<stdio.h>voidmain(){inta,b,c,d;scanf("%d",&a);b=a/100;c=(a%100)/10;d=a%10;printf("%d",100*d+10*c+b);}
