[un]各位大哥，小女子初学C，老师让做一个小程序已验证“哥德巴赫猜想”：当输入一个大于6的偶数时，就会分解成两个素数，以下程序我调试了一下，只能判定能分解为带3的偶数，百思不得其解，万望赐教，呵呵[un][/un][/un]





#include "stdio.h"
void main ()
{
    int a,b,c=1,d=1,m,n,s,i=3,j,k;
     printf ("请输入一个大于6的偶数:\n");
     scanf("%d",&s);
     if(s<=6)printf("Sorry ,the number you input is not bigger than 6\n");
     else if(s%2!=0)printf("sorry , the one you input is not an even number\n");
     else
         for (i=3;i<s;i++)
            
         {
             a=i;
             b=s-i;
             for(j=2;j<a;j++)
             {
                 m=a%j;
                 c*=m;
             }    
             for(k=2;k<b;k++)
             {
                 n=b%k;
                 d*=n;
             }
             if((d!=0)&&(c!=0))
                 printf("%d=%d+%d",s,a,b);
         }
}

呵呵，你的程序我看了，没看懂，哈哈，不过还是很感谢
