C语言输入一个整数计算它的绝对值

一：#includevoidmain(){inta,i=0,sum=0;scanf("%d",&a);while(a){sum+=(a%10);//sum是个位数之和a/=10;i++;//i为位数}

#includeintGetNumber(intn)//用递归来实现很简单{intsum=0;if(n/10!=0){\x09sum+=GetNumber(n/10);}sum+=n%10;retur

#includevoidmain(){inta,b;printf("Inputtwointegers:");scanf("%d%d",&a,&b);printf("和:a+b=%d\n",a+b);p

#includemain(){inti=0,s=0,n;scanf("%d",&n);while(n>0){s+=n%10;i++;n/=10;}printf("%d%d\n",s,i);}

#includeintfun(intn){ints=0;while(n){s+=n%10;n=n/10;}returns;}main(){intn;scanf("%d",&n);printf("%d\

#include"stdio.h"#include"math"main(){intx,s,i;printf("inputanumber.");scanf("%d",&s);dowhile(s

你的程序中判断素数并加和的部分有问题在你的基础上修改如下PS:main不需要改动# include <stdio.h>int SumPrime(int&nbs

#include"stdio.h"intmain(){inta[10][10]={0};intn,i,j,sum1=0,sum2=0;scanf("%d",&n);for(i=0;i

main(){inta=0,i;scanf("%d",&a);for(i=0;i

给你写了个,运行通过,你看看吧,记得采纳哦O(∩_∩)O~#includeintmain(){\x09intnum,i=0;\x09printf("pleaseinputanumble:");\x09

#include#include#include#includeusingnamespacestd;//计算num内的所有素数（不包括num）voidCalcPrimes(intnum,vector&

#include"stdio.h"intmain(){inta,i,sum=0;printf("请输入3位的整数\n");scanf("%d",&a);for(i=0;i

for{i=i;i再问：printf印出n!=%d*%d*%d*%d*%d...=%d可是我不知道要如何写才能分解成1X2X3X4X5...这样的,例如我输入8,我想印出1X2X3....X8=%d这

方法一：//用数学函数#include#includevoidmain(){inta;scanf("%d",&a);printf("%d\n",abs(a));}方法二：//判断#includevoi

//#include"stdafx.h"//vc++6.0加上这一行.#include"stdio.h"voidmain(void){\x05intn,sum=0;printf("Typeaninte

#include#include#defineE2.7182voidmain(void){floatx;floaty;scanf("%d",&x);if(x>=-1)y=pow(x,2)+1;

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

#includevoidmain(){\x09longa;\x09printf("inputanumber:\n");\x09scanf("%d",&a);\x09if(a%3==0&&a%5==0&

不明白楼主让用C语言,大家怎么都用C++ #include<stdio.h>void main(){ int num,temp,number=0,s

#include<stdio.h>/**Author: QCQ*/long factorial(int number);void printout(
