C语言编程判断输入整数x的正负性和奇偶性

#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

楼上是C++写的,这个是C语言版的#include#includeintmain(){intcount;int*arrayLenth;int**intArray;int*elem1,*elem2;in

#includevoidmain(){intx,a,b,c;scanf("%d",&x);a=x/100;b=x/10%10;c=x%10;x=c*100+b*10+a;printf("%d",x);

第一题：#includeintprime(inta){inti;for(i=2;i

#includeintmain(){intn;scanf("%d",&n);if(n>0){if(n%2)printf("此数为正数且为奇数.");elseprintf("此数为正数且为偶数");}e

#includevoidmain(){inti,k,n=0,m=0;floatfu,zhen;inta[10000];k=0;while(scanf("%d",&a[k])!=EOF)k++;fu=0

#includeintmain(){inti;voidfun(inta);printf("输入数字：");scanf("%d",&i);fun(i);return0;}voidfun(inta){if

除数为0时怎样做、不为0时怎样做,不用分支结构是处理不了这种问题的,亲.再问：大哥、、、、求解。。。我郁闷了。。。再答：汗，唯一的办法就是用分支结构，if(b=0){//输出错误信息printf("除

a=input('请输入一个整数:\n');ifsign(a)==1&&mod(a,2)==0disp('正偶');elseifsign(a)==1&&mod(a,2)==1disp('正奇');el

#include"stdio.h"main(){inta=0,b=0,c=0,d=0;printf("请输入两个整数：");scanf("%d,%d",&a,&b);if(b==0)printf("输

先写个函数判断n1、n2、n3大小,假设n1再问：怎么弄出n1n2n3的大小啊再答：//传入三个参数n1、n2、n3的引用，程序运行完后满足n1

a+b>cabs(a-b)再问：能编个完整的给我吗？谢谢。新手，看不懂啊……不胜感激再答：#includeinta,b,c;scanf("%d,%d,%d",&a,&b,&c);if(a>0&&b>0
