Suppose we have the function :
void foo(int x)
{
foo(x);
}
on my machine (i7) will run approximately 260k times and generate segmentation fault. any idea why that happens ?
Every time you call a function, it require space on the runtime stack. This is where variables local to that function have their memory allocated. What’s happening is that you’re recursing so many times that you’re running out of stack space — a stack overflow. (The name of this site!)
