7.输入一个整数,判定它是否为素数.

///c语言的,#inlcudevoidmain(){inta;printf("pleaseinputanumber:\n");scanf("%d",&a);if(a%5）printf("thisnu

#includevoidmain(){inta,b,c;printf("请输入一个大于3的数\n");scanf("%d",&a);for(b=2;a>b==1;b++){c=a%b;if(c==0)

多的我就不说了,函数如下（你只需把下面的代码贴在intmain()之前就行了,然后在开头加一个头文件：#include）：boolisPrime(intx){if(x==1)return0;for(i

varn:longint;beginreadln(n);ifnmod7=0thenwriteln('yes'){除以7取余,是否等于0,等于则输出yes,否则输出no}elsewriteln('no'

intx;if(x%2==1){System.out.print("奇数");}else{System.out.print("偶"}大致意思你应该能看懂吧!我用手机打得会有些语法错误!定义得x就是输入

一个个试或者运用数论里的素性判定的知识

#include#includeintmain(){printf("请输入一个正整数：");intn1,n2;boolflag1=false,flag2=false;scanf("%d",&n1);n

c:voida(inti){if(i%2==0)printf("偶数");elseprintf("奇数");}手写的,没调试

if(flag==0){\x05intiLast,iNext;\x05iLast=sqrt(nums);\x05iNext=iLast+1;\x05printf("itisnotaperfectsqu

#includemain(){intn;printf("输入年份:");scanf("%d",&n);if(n%4==0&&n%100!=0||n%400==0)printf("闰年\n");else

#include <stdio.h>#include <math.h>int main(void){    

PrivateSubCommandButton1_Click()DimnNumAsLongIfIsNumeric(TextBox1.Text)ThennNum=Val(TextBox1.Text)If

cmain(){doublea;scanf("%lf",&a);if(a>=500&&a

#include<iostream>usingnamespacestd;intmain(){\x05floatkey=8;\x05chara[4];\x05char*p=(char*)(&

vari,n:longint;b:boolean;beginreadln(n);b:=true;ifn
