C :: Adjacent And Opposite - How To Get Tangent Inverse
Aug 12, 2013I have an adjacent and opposite. I think I can use: tan(x) = opposite / adjacent but how do I get the tangent inverse?

View 2 Replies View RelatedC :: Why Constants And Variables Stored In Memory In Opposite Order Called
May 23, 2014I'm playing around and wrote a tiny program.
Code:
char bracketin[] = "thisgetsbracketed.txt";
char bracketout[] = "bracketed.txt";
char testwalk[10] = "12345678";
[Code]....
I'm incrementing the pointer to buffer 150 bytes beyond its reserved 50. I see testwalk, followed by bracketout, followed by bracketin printed by the overflow on buffer.
The memory locations are ordered descending from their call order. Why is this the case?
One would think that they would be written in ascending order as I call them. I can only assume that they're compiled bottom up - where could I read about this process?
C++ :: 4x4 Matrix Inverse Implementation
Sep 19, 2013I'm implementing a 4x4 matrix class and all is going well until the inverse function turned up. I'm trying to implement the inverse function, but I can't seem to get my head around it.
I've tried the internet, but found nothing useful. Also, I've looked into source code of other programs/libraries that implement a matrix class, but the code is unreadable.
How I can implement this damn 4x4 inverse function? I know the process of inversion, but putting that process into code is proving quite a challenge.
In addition, I do have some code, but it's unmanageable and inefficient at the moment. If you want to see it, just ask.
Additional question(s): What applications does the inverse matrix have in 3-D?
C++ :: Take (mathematical) Inverse Of Array?
Feb 17, 2014I need to take an array, and get the inverse of it (basically, just how you would take an inverse of a function in math). I need to do it where, if a[i] = x, b[x] = i. I would just copy from array a to array b in a function.

Dec 25, 2014Print the inverse number. Ex: 2178*4=8712
Write down a program which can satisfy the prerequisite and print out the screen.
The answer is:
Code:
void inverse2 ()
{
int i,j;
for (i=1000;i<=9999;i++)
for (j=1;j<=9;j++)
if (i*j==inverse (i))
printf("%5d%2d",i,j);
}
I can't understand the double for loop.
for (i=1000;i<=9999;i++)
for (j=1;j<=9;j++)
And The meaning for
i*j==inverse (i)

Sep 3, 2014Write a program to read strings from the standard input, concatenating what is read into a large concatenated string next ( ok I wrote this program and it works properly ), change the program to separate adjacent input strings by a space ( problem with the second part ). In my book i learnt the difference between the string input operator and the getline function, size member function, empty , but i can't undersand how to read two adjacent strings and how to separate them.....

C++ :: Calculating The Inverse View Matrix From Computer Graphics
Feb 6, 2015How do you calculate the inverse view matrix?
Is that really just the inverse of the view/camera matrix?
Or is that something else?
I have seen articles online on the overall mathematical theory behind it but I am using the GLM math library and it has this nifty glm::inverse() function.
I was just curious if I can do a glm::inverse(ViewMatrix) and that would be correct.
C++ :: Swapping Two Adjacent Linked Lists Nodes
Oct 22, 2014I am working on a program where I sort elements into alphabetical order and then when one is less than the other I swap them. I first did it by swapping the data but they want me to swap the nodes instead and I am having trouble doing that.
Node *add_node( Node *list, const string &s ) {
struct Node *n = new struct Node;
n->word = s; // copy string s to word
n->next = 0;
// add node n to the list
// the list should always be in ascending alphabetical order
n->next = list;
list = n;

C/C++ :: Using Linked Lists To Swap Two Adjacent Elements
Jan 6, 2015I am reading a book currently on data structures in c++. The questions I have is how I would be able to swap two adjacent elements by adjusting only the links (not the data) using, a) singly linked lists, doubly linked lists.
For the single linked list which I am somewhat familiar with (by the content of the book), I would consider taking the Node A, and copying its data into a new Node temp, then re-routing the pointer from whatever connected to Node A, now to Node temp. now I want to re-route the pointer of Node B to Node temp and Node temp to whatever Node was being connected from Node B. Is this the correct approach?
