运行时错误（SIGSEGV）

Question

I am new to coding. When I am submitting my code in codecheff its giving "Runtime Error(SIGSEGV)". I Don't know what's the problem please help. Thanks in advance.

int call(int *x, int m)
{
   int b[10], y, z;
   for(y = 0 ; y<m ; y++)
   {
      int sum = 0;
      z = *x;
      while(z>0) {
         sum = sum + z/5;
         z=z/5;  
      }
      b[y] = sum;
      x++;
   }

   for(y = 0 ; y<m ; y++)
      printf("\n%d", b[y]);
}

int main() 
{
   int n=0, i=0, a[10]; 
   scanf("%d", &n);
   for(i=0;i<n;i++){
      scanf("%d", &a[i]);
   }
   call(a, n);
   return 0;   
}

If you're getting SIGSEGV, it means you're trying to access memory in a segment your program does not have access to, or you're trying to access memory your program has access to in an invalid way.

Your first course of action should be to use Valgrind or Dr. Memory, when you have a memory segmentation error like this.

Based on your code, I'd assume you may be having a problem when n > 10 that is causing a buffer overrun in b and x. If you named your parameters to something meaningful, it would be easier for us to solve.
