#includeintmain(){inta[40],sum=2,i;a[0]=1;a[1]=1;for(i=2;i

intmain（void）｛inti,ans;For(i=1;i再答：��ټ�һ��#include再问：лл

#include#include#includeintmain(void){longn,x,jc=1,t;doublesum=1;scanf("%d%d",&n,&x);for(inti=1;i再问：

#include#includeintmain(void){intn;doublei,j,k;doubleres=0;printf("pleaseinputn:");scanf("%d",&n);i=

帮你写好了.unsigned int fib(unsigned int n) {\x09if (n == 1

#include "stdio.h"void main(){ int n,sum=0; printf(&q

#includeintmain(){intx;inta[20];scanf("%d",&x);inti;for(i=0;x>=10;i++){a[i]=x%10;x=x/10;}

你写的scanf就提出了要求的输入是“数a”“逗号”“数b”,你既然没有给出逗号,那就一直没有给b赋值,你也没有给b一个初始化的值,那么得出的结果就是一个随机数.可以把逗号去掉,这样两个数字之间用个空

/*1-2/3+3/5-4/7+5/9-6/11+.的前n项之和*/intmain(intargc,char*argv[]){intnum_n=1;inti=0;doubleresult=0.0;pr

#includeintmain(){inta=2;intc=3;intsum=2;inti;for(i=1;i

#includevoidmain(){inti=0,j=0,k=0;for(i=1;i

#includeintmain(){inta,b,c,min,max;printf("请输入三个数,用空格键隔开");scanf("%d%d%d",&a,&b,&c);min=ac?b:c);prin

#includeintmain(void){intn=0,i=0;doublep=1,q=0,s=0;printf("n=");scanf("%d",&n);for(i=1;i

main(){inti,n,sum=0;scanf("%d",&n);n*=2;for(i=1;i

不用那么麻烦inta=1,b=2,i,k,n;floatsum=0.0;scanf("%d",&n);for(i=0;i再问：不是题目要用递归函数

#includemain(){inti,j,n,k,t;doublesum=2;printf("inputanumber:\n");scanf("%d",&n);j=2;k=1;for(i=1;i再问
