How to link 2 variables?

16 Aug 2013 by pasztorpisti

Simple: You have to return two values: an angle and a motor index. Your code also has a bug, max_angle isn't initialized. For two fixed values its an overkill to use a for loop. Using a for loop would be reasonable only if the input angles were in an array. Passing in the motor indices is also a...

array of structures dynamic allocation

12 Aug 2013 by Sergey Alexandrovich Kryukov

It's malloc, please see:http://www.cplusplus.com/forum/articles/416/[^].Please don't forget free.Why do you thing your allocation should be dynamic? You don't have variable number of structures; in your code, it's the immediate constant 4, which is, by the way, always bad. You should...

get and set value from the same function with the same params

6 Sep 2013 by OriginalGriff

You can't, not without changes to your function - it returns an integer - the value of the node - rather than the node itself, so the code fragment you show:list_element_at(listo , 2 ) = 50;Is the equivalent of trying to say:17 = 50;Which no modern compiler will allow you to do, for obvious...

get and set value from the same function with the same params

6 Sep 2013 by nv3

The solution is simple: You just have to return a reference to data member:int32& list_element_at(llist list, int32 n){ ... return temp->data;Just a single ampersand and you are done :-). Now, what that causes behind the scenes is that the compiler will pass a pointer to the...

VC6 Text Files: Reading a text file of type ANSI and unicode using CStdioFile

assign array of structures

13 Aug 2013 by The_Inventor

It is pretty obvious that in your code, that you are not showing, that when you calc the torque, you are not saving it to temp_value or don't assign the calculated answer to the temp_value, so the original value of temp_value is still = 0;temp_value = another_function(joint[index]);but it...

13 Aug 2013 by CPallini

7 Sep 2013 by H.Brydon

If there is a counter in the head object and an index in each node, then removing a node in the middle will cause inconsistency in at least 2 places. There is no way to come up with a situation or algorithm that will fix this. Your program and how you use the data will need to reconcile this...

8 Sep 2013 by nv3

The method you describe in solution 2 is not an option. You are not allowed to move nodes in memory, because all next pointers will be pointing to the wrong place. A single big memmove would also assume that the remaining nodes in your list are in a contiguous memory block, which they are...

I think i have found the solution, after freeing the desired node, i make memmove to the rest of the list to shift (sizeof(struct node)) left, now in order to get element at specific index we can use memory address and discard the index member, for examplethe head is always the first and then...
