vb编程求1 2 3 N-搜答案-大师作文网

Dimn,x,r,sAsSinglen=2s=0DoWhilen再问：能说一下算法的思路吗？再答：首先1不是素数,就用枚举将2到1000的每个数列举出来,再逐个检验,即从2到n/2一一举例，判断是否能

n=val(inputbox"请输入一个数字.")fori=1tona=a+inextiprinta

#include#includemain(void){intn,i;printf("请输入n的值\n");scanf("%d",&n);intsum1=1,sum2=2,sum;for(i=3;i

是没有思路,还是不会编程?至少有一位数字是5用以下的子函数boolIsInclude5(intnum){while(num!=0){if(num%10==5)returntrue;num=num/10

简单就是不会再问：....再答：不是不会是好久没做了差不多都忘了呵呵

很简单的~不过你问错地方了
