编写程序,输入一个整数,输出该整数是正数还是负数

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

voidmain(){inta;scanf("%d",&a);if(a%2==0){printf("偶数");}else{printf("奇数");}}programJO;vara:integer;b

#include//这是c语言的一个标准库,包含它才能用函数intmain()//这是主函数,c语言的工程都是由大小的函数组成的,主函数是系统运行的第{//一个函数inta,b,c;intmax;pr

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

#includeusingnamespacestd;intmain(void){floatf;scanf("%f",&f);printf("整数部分:%d\n",int(f));printf("小数部

可以把浮点数当初字符串来处理字符串处理函数如下：voidcut(string&str){intn=0;n=str.size()-1;stringcutter(n,'');stringstr3(n,''

scanf("%d,%d,%d,&a,&b,&c");改成scanf("%d,%d,%d“,&a,&b,&c);printf("thelargerstnumberis%d\n,max");改成prin

#includevoidmain(){inta,i=0,b[3];printf("inputathreebitnumber\n");scanf("%d",&a);if(a>=100&&a=0;j--)

importjava.util.Scanner;publicclassJiecheng{Scannerin=newScanner(System.in);inta=in.nextInt();int

算法分析:把输入的三位数分解(百,十,个);再交换个位和百位就可行了.#include{intn,a,b,c,x;printf("请输入一个三位数：\n");scanf("%d",&n);a=n/10

#includemain(){intn,i;inta[10];printf("请输入个数n:");scanf("%d",&n);for(i=0;i=0;i--)printf("%d\t",a[i]);

#include#include#includeintmain(){inta[10];//每个数字的计数器intnum;inti;charch[100],*ch1,num1;for(i=0;ia[i]
