c语言在键盘上任意输出三个数,按从大到小的顺序排列.

程序没有错,输入时错了.因为scanf规定的是以空白符（如空格）作为每个输入变量的分隔符,不能象你那样用逗号分隔.你把输入改成123就可以得到正确答案了.

第一个题:#include"stdio.h"main(){inta,b;scanf("%d,%d",&a,&b);printf("a+b=%d",a+b);}结果:5,7a+b=12第二个题:#inc

intmain(){intn,n1,n2,n3,n4;cin>>n;n1=n/1000;n2=(n%1000)/100;n3=(n%100)/10;n4=n%10;n=n1+10*n2+100*n3+

#includeintmain(){inta,b,c;scanf("%d%d",&a,&b);c=a*b;while(a){if(a

#includevoidmain(){inta,b,c;intd,e,f,sum;printf("请输入三个整数：\n");scanf("%d,%d,%d",&a,&b,&c);//分号放错位置了su

#includeintmain(void){inta,b,c,t;printf("请输入三个数");scanf("%d%d%d",&a,&b,&c);if(a

#includeintmain(){intx,y,a;scanf("%d",&x);scanf("%d",&y);a=x*y;printf("Theaverageis%d\n",a);return0;

#include<stdio.h>void main(){    int num;    

scanf("%d.%d,%d",&a,&b,&c);是输入格式有问题吧,应该为scanf("%d,%d,%d",&a,&b,&c),输入1,2,3这样才能正确读入.还有intmax(intx,int

voidmain(){inti,j,k=0,a,s[50];for(i=0;i

IF的嵌套太乱,并且输出了太多的无用信息.三个排序,设为其a,b,c思路就是：先比较a,b,如果a>b就把a,b调换；再比较a,c,如果a>c就把a,c调换.这样一来,第一个数必为最小.最后比较二三个

#includevoidmain(){floata=0,b=0,c=0;chard;printf("输入两个数:\n");scanf("%f%f",&a,&b);getchar();printf("选

intmain(){inti,n;cin>>n;if(n
