C语言程序设计，输入一个四位正整数，将它们倒排输出的算法如下：includeincludeintmain(){intoldnum;intnewnum=0;inttemp;printf("pleaseinputnumber\n");scanf("%d",&oldnum);printf("theoldnumberis...

答案[9]=newNum*10[10]=[11]=num/10[12]=invert(num)参考网址：网页链接

先写出其倒序，然后求其和。具体程序代码如下：include"stdio.h"intmain(){intx,y;//x是原数字，y是倒序后的数字printf("请输入原数字:");scanf("%d",&x);if(x>9999)printf("输入数字不能超过9999");...

//数学法#include<stdio.h>intmain(){intnum;do{scanf("%d",&num);}while(!(num>999&&num<10000));while(num){printf("%d",num%10);num/=10;}return0;}//string库法#include<stdio.h&

include<stdio.h>intmain(){intn;printf("输入正整数:");scanf("%d",&n);while(n){printf("%d",n%10);n/=10;}return0;}

printf("-");n=-n;}while(n){printf("%d",n%10);n/=10;}}return0;}
