#includeintmain(){floatr,s,l;scanf("%f",&r);s=3.14*r*r;l=2*3.14*r;printf("s=%f,l=%f\n",s,l);return0;
#includeintmain(){inta,sum=0;scanf("%d",&a);while(a){sum+=a%10;a/=10;}printf("sum=%d\n",sum);return0

已经运行确认了:#includemain(){intavg,i,sum=0,a[11];printf("请输入十个整数\n");for(i=1;i
1:#includeintmain(){intnum,sum=0;while(scanf("%d",&num)==1&&num>0){sum+=num;\x09}printf("结果为%d",sum)

代码:#include <stdio.h>int sum(int n){\x05int s = 0;\x05while(n>
#includevoidasum(doublea[3][3],doubleb[3][3],doublec[3][3]){inti,j;for(i=0;i
scanf("%f",&r);scanf("%f",&h);改成:scanf("%lf",&r);scanf("%lf",&h);因为你的变量r,h声明的是double类型的变量.同样printf("
你的main写错了啊你写成了mian()...再问:。。。。。谢了
#includevoidmain(){inta;printf("请输入一个三位数:");scanf("%d",&a);printf("各位数上的乘积为:%d\n",(a/100)*(a%10)*(a/
#include<stdio.h>void main(){ int sum=0; &nb
#includeintmain(){doubleR;while(scanf("%lf",&R)!=EOF){printf("%lf\n",R*R*3.14);}return0;}

1.编译不通过数组定义时,不能使用变量,即使变量已赋值,所以inta[n];是错的解决方法,你可以直接定义一个大的数组,比如inta[100],然后再用n限制输入的个数2.数组下标是从0~n-1,所以
#include<iostream.h>#include<stdio.h>#define PI 3.1415926int main(){ 
#include"stdio.h"main(){floata,b,c,p;loop1:printf("pleaseenterpianshanga:\n");scanf("%f",&a);printf(

#includevoidmain(){inta,b,c,d;printf("Pleaseinput3numbers,example,[1,2,3]:\n");scanf("%d,%d,%d",&a,&
#includevoidmain(){intn,i,m,t,a[100];for(n=1;n
