While debugging I found in "else if" part the if(temp->parent==temp1) statement is not checking true or false. Control directly jumps to the Send() function. Please let me know where it is going wrong.
else if(I_Send(my_rank,global_parent,&dest,num_procs))
{
if(temp->parent==temp1)
{
fix_node[my_rank]==temp;
}
Send(fix_node[my_rank],L,sz_vec[fix_node[my_rank]->node_num],fix_node[my_rank],dest,temp1);
temp1=temp1->parent;
if(temp1!=NULL)
local_parent=temp1->node_num;
}
The code inside the if body has no effect...
fix_node[my_rank]==temp;
I think you meant to do an assignment (=) instead of comparison (==)

Is there a way to terminate a C++ string at any arbitary location. This is very easy in C as we can just insert a null character wherever we want. But how can the same be achieved in C++ String.
For example, Let's consider the following example,
string str = "This is Stack OverflowXXXX";
Now I want to terminate this string so that I would get "This is Stack Overflow".
Yep! Use string::erase:
str.erase(k);
will erase all characters from position k forward. There's no way to "undo" this to get those characters back, though.
Hope this helps!

int x;
x=x+30;
cout << x;
the output will be 33, why is it so?
I didn't even declare x as 3.
Can someone guides me? Thanks!
Using an uninitialized variable is undefined behavior. You got 33 due to an unreliable sequence of implementation quirks. The program is free to produce any value at all, fail to compile, or hire an assassin to stab you.
In C++, variables are given space (memory allocation) by default equal to the size of the variable, but they are not given values by default.

I have a 2500 line and 76.8 kb c++ console program. I learned inline function but heard about inline function makes a trouble in huge programs. Is it true? This program is huge or not. It can be a trouble in the future. What should i do or what is your suggestion for me.
Note:Program include lots of functions.
Thanks!
Is it true?
You can check out the advantage and disadvantages of Inline Functions and justify it

As mentioned in the question, I have a segfault in the implementation of Conway's game of life in gtkmm that I am working on.
It can be found here: https://github.com/sakekasi/game-of-life
The backtrace of the error can be found here: https://gist.github.com/3505525
When I insert print statements in cells_get or create_updated grid, it starts printing, doesn't produce a segfault and goes on forever without doing anything.
create_updated_grid is accessing cells off the edge of the grid. It's calling things like cells_get(i+1,j).
You need to change your out-of-bounds checks in cells_get to >=, not >.
