c语言输入一个整数统计该数中2的个数

#includevoidmain(){inti,n,z,f,x;printf("请输入一共要处理几个数：");scanf("%d",&n);for(i=z=f=0;i0)z++;elseif(x

#includevoidmain(){intn;printf("输入一个整数：");scanf("%d",&n);if(n%2==0){printf("%d是偶数\n",n);}else{printf

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

#include#defineCOUNT100main(){inta[COUNT],i,x,no=0;for(i=0;i

#include<stdio.h>int main(){int n,max=-1,s=0;scanf("%d",&n);while(n

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

#includeintmain(){intnum=0;ints=0;inti=0;scanf("%d",&num);while(num){s+=num%10;num=num/10;i++;}print

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

Reverse

可以用sprintf(str,"%d",num);将数字输出为字符串,再用strlen(str)检查其长度：intnulen(intnum){charstr[10];sprintf(str,"%d",

#includevoidmain(){inta[10];inti,n=0;floatsum=0;for(i=0;i

if(x%5==0){g=g+1;sum3=sum3+x;}}}//下面的大括号拿到这里printf("奇数之和为%d\n",sum1);printf("偶数之和为%d\n",sum2);printf

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

#includevoidmain(){inti,n,count=0;for(i=0;i=0)count++;}printf("正数的个数为:%d\n",count);printf("负数

修改如下：1.主函数中intcountdigit,digit=2,number中,countdigit重复定义,改为其他变量,比如x2.改为scanf("%d",&number);3.printf("

#include#includeboolisPrime(intn){if(n==1)returnfalse;for(inti=2;i*i
