Why this code is not give any output?
When i run,it gives me ERROR like SEGMENTATION FAULT CORE.
(C language)

#include <stdio.h>
void fun()
{
int arr[5] = {1, 2, 3, 4, 5};
int i, j;
static int n = -1, b = 0,k = 1;
int mari[5];
int max = arr[0];
if (k > 5)
return ;
for (i = 0; i < 5; i++)
{
if (arr[i] >= max)
{
for (; b <= 0; b--)
{
if (mari[b] == i)
{
continue;
}
max = arr[i];
n = i;
}
}
}
mari[b] = n;
b++;
k++;
printf("sdg %d", max);
fun();
}
void main()
{
printf("%d", fun());
}
