为什么总是runtimeerror小弟的程序提交总是说RUNTIMEERROR
一般是什么原因造成的,小的新手,请多多指教,感激不尽!
#include<stdio.h>
#include<math.h>
#define arr 5
int test(int m)
{
int i,n;
n=(int)sqrt(m);
for(i=2;i<=n;i++)
{
if(m%i==0)
return 0;
}
return 1;
}
main()
{
long a[arr],j,i=0,h,pos1,pos2,pos,k;
while(1)
{
scanf("%ld",&a[i]);
if(a[i]==0)
break;
if(a[i]<6||a[i]>=1000000)
i--;
if(a[i]%2)
i--;
i++;
}
for(h=0;h<i;h++)
{
for(j=2;j<=a[h]/2;j++)
{
pos1=test(j);
if(pos1==1)
{
pos2=test(a[h]-j);
if(pos2==1)
{
pos=j;
break;
}
}
}
printf("%ld = %ld + %ld\n",a[h],pos,a[h]-pos);
}
getch();
}
