Experiments with fork bomb

int main(){
while(1)fork();
return(0);
 }

• What are different ways in which you can limit the fork bomb?
• How pid’s are allocated during fork bomb ?
• Check out the strace of a fork bomb program ?

Program and memory access patterns

Which will work, which will not and why?

int main()
{
   char *p;
   p="abc";
}

int main()
{
	char *p="a";
	strcat(p,"bc");
}

int main()
{
	char *p=malloc(sizeof(char)*10);
	strcpy(p,"hello!")
}
