I could fix some bugs. It is running the test. I am not sure if someone is up for it but at least I get motivation to test more by posting here.

Strangely, the hyperlink does not work I don't know why, you can still copy paste the links.
Anyway, here is the assignment:
Memory: User created Heap
write a program to have an array of 2mb character storage. segment the memory
into a linked list as per following rules:
1.each node in the list has a header and payload.
2.header should have 2 members

After calling fork do something like following in your code for the child
Code:while (getppid()!=1) //One is the pid of init and if the parent dies new ppid = 1 { sleep(10); } //do the rest work here //THis will ensure that the child does not do any work until it is adopted by initLeave a comment:

this question always gets you till you know the trick.
Insert the node after the node to which you have a pointer.
Swap the contents of both the node.
Thats it....Leave a comment:

dlls and shared objects
am looking for a tutorial/resource on the concept of dll s and shared objects.
How they are created and when where and how they are loaded and by whom.
Also it would be nice if the experts would put them in here. -
Even this will work, i did not understand moderator's post
[CODE=CPP]
void printarray(int args[][],int rows,int cols)
{
for(int i=0;i<rows;i++)
{
for(int j=0;j<cols;j++)
cout<<args[i][j]<<endl;
}
}
int main()
{
int firstarray[][2] = {{1,2},{3,4}};
printarray(firs tarray,2,2);
}
[/CODE]Leave a comment:

[CODE = c]
void func(int array[][], int row,int col)\\
{
/*this is just a proof*/
}
int main()
{
int a[5][5];
func(a,5,5);
return 0;
}
[/CODE]
This compiles without any problem for meLeave a comment:

Ha ha ha ha, you sound like
Please make a chess program for me.
Jokes apart, it takes more discipline than attitude to create such a program.
I would greatly discourage using TURBO C. but you seem to have decided.
WHATEVER THE design decisions your seniors have taken, if thats how they achieved it great, you can do the same its already proved.
You will have to post your efforts...Leave a comment:

Well in DOS those characters are part of character number 127 to 255.
For other OS I am not sure, i think unicode could be a correct ideaLeave a comment:

Just to add,
C++ standard container define a method capacity, though not related to your question you might want to know about them. If you know already please ignoreLeave a comment:

I will xplain my understanding.
1. In one word the answer is "yes" on unix. That is you, as a application writer should be able to retrive the size of the memory allocated from the pointer. But there is more.
I will tell you how all this happens in linux, I have some intution on windows but not sure.
When you make a call to malloc, it allocates a block of memory from heap to your program. And...Leave a comment:

...Code:int main() { pid_t pids[4] = {0,0,0,0}; //be careful with these pid_t parentid,childid,myid; int i; //why do you want to initialize these with 4 int status; parentid = getpid(); //this is the original pid of the parent for( i =0 ;i < 4 ;i++) { myid = getpid(); if (myid == parentid) //only the parent forksLeave a comment:

Ok first lets try to identify whats wrong with your code.
1. A call to wait requires a pointer to an integer which will contain the exit status of the child. Your call will try to write the status to a memory location 3, which is most liable to crash the program.
2. You see to assume that a call like wait(3) will exit when the third process exits, I guess you are absolutely wrong, there is nothing like that.

Do that and you are out of business.
1. you will lose elements as you are not swapping them just replacing and by the time you get to the other elements you are lost. So replace this simple statement be three statements , that first saves the target elements before swapping.
2. Now even if you fixed that in step 1. You are lost because, you will be first swapping and then re-swapping. the two nested loops are not enf,...Leave a comment:

1. Are you sure this is correct crossover logic, you ar enot using parent at all.
2. See the trouble is you are passing the child pointers be value so whatever change in the address of child pointer value you willmake wills tay local to function. So you will have to pass a pointer to pointer to child so that the change is available with the returned function.
So what exactly are you doing with GA. GA is cool...Leave a comment:
