c语言实现删除一个数,该数从键盘上输入

#include#includeintmain(){\x09doublex;\x09scanf("%lf",&x);\x09printf("%lf\n",sqrt(x));\x09return0;}

#include <stdio.h>int main(){\x09int n;\x09int nConut = 0;\x09sc

#include <stdio.h>int main(){\x09int n,i=0,j=0;\x09scanf("%d",&n)

elseif(a=i)应该改成for(a=2;a=gh2){printf("%d是质数\n",i);gotoloop;}}因为当i>2时sqrt(i)肯定比i小,你原来的elseif(a==i)肯定判

#includeintmain(){inta;inti;intresult=1;printf("请输入一个奇数\n");scanf("%d",&a);if(a%2==0)printf("这不是奇数\n

intfun(intn){returnn%2;}intmain(){intn;printf("\n输入要判断的整数");scanf("%d",&n);if(fun(n)==0)printf("\n%d

longsum;sum=0;inta,tmp;a=1;tmp=a;for(inti=0;i

swap(int&i,int&j){inttemp;temp=i;i=j;j=temp;}main(){inta,b,cscanf("%d,%d,%d",a,b,c);if(a

可以写个函数intsheru(doublei){doublea=i-(int)i;//求此浮点数的小数部分if(areturnint(i);//如果小数部分小于0.5.则返回整数部分.double强制

#includeintmain(){intnum;inta,b,c;scanf("%d",&num);a=num/100;b=(num%100)/10;c=num%10;printf("a=%d,b=

#include"stdio.h"intmain(void){longnum;intn=0;scanf("%ld",&num);while(num){n++;num/=10;}p

#include"stdio.h"#include"stdlib.h"intf(intn){while(n>=9){if(n%10==9){return0;}else{n=n/10;}}return1

#includeintmain(){doubled;printf("inputd:");scanf("%lf",&d);printf("%.1lf\n",d);//输出保留一位小数,自动四舍五入ret

问题：一整数,它加100后是完全平方数,再加168还是完全平方数,求该整数解题思路：设该数为x,它加100后是A,再加168为B.则因为A是完全平方数,所以A为正数,且A=y*y,y为正整数或0.同理

if(r=47)这是明显的语法错误,　应该是if(r==47)

是输入字符串,还是一个int再问：int再答：#include<stdio.h>void main(){    int a,b=

你好.看代码#includevoidsort(int*a,int*b,int*c){intt;t=*a;*a=*a>*b?*a:*b;*b=*a>*b?*b:t;t=*a;*a=*a>*c?*a:*c

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

#includeintfindmax(inta,intb){if(a>b)returna;elsereturnb;}intmain(){inta,b,c;scanf("%d%d%d",

#includemain(){inta,b;scanf("%d",&a);for(b=1;
