I want to to divide a cell into 4 different regions using x_coordinate, y_coordinate (for outer sectors) and by defining radius (for center region). I tried my best by i couldn't figure out how to do this in C. I am attaching the diagram of the cell for better understanding. URL...
View 1 RepliesI have an array of size m and r resources. What would be an efficient (or just any) way of distributing them in the way shown in the table? The highest amount of resources must be concentrated in the middle of the array and all the resources must be distributed.
I'm not really set on exactly how steep the "slope" must be, I just need a way of approaching the problem.
Example with m=9 and r=13

How to get value from datagridview of frmMaterialList into textbox of frmMaterial?
Note: frmMaterial has a button to load frmMaterialList
I would like to draw a border arround a cell in a TableLayoutPanel but without also making a connection between the columns. I just want an outer border.
private void tableLayoutPanel1_CellPaint(object sender, TableLayoutCellPaintEventArgs e) {
if (e.Row == 0) {
e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Right, e.CellBounds.Top));
e.Graphics.DrawLine(Pens.Black, new Point(e.CellBounds.Left, e.CellBounds.Bottom), new Point(e.CellBounds.Right, e.CellBounds.Bottom));
e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Left, e.CellBounds.Bottom));
}
}
This line
e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Left, e.CellBounds.Bottom));
also paints connections, where i don't want them. How can i just make a outerb order arround a cell and is there a easier way to do it? Here's also an image of what i want. I don't know if i described it right.
I want to display the content of point "cell", how can I implement this:

I'm currently working on a Scheme Interpreter written in C. I'm trying to create a cons cell structure via recursive descent parsing, except instead of just having the car and cons, I also have a field that holds the token that I receive from the lexical analyzer (which was provided to us). The struct for what I'm describing is as such:
typdef struct node node;
typedef node* list;
struct node {
char* symbol;
list car;
list cdr;
};
Thus a cons cell would be (with a node represented as [symbol][car][cdr]), [null][car][cdr], while a symbol would be [symbol][null][null].
In the top answer for a similar question on Stack Overflow, one of the suggestions was to put the tokens into a stack as the input is recursively parsed, and then from that stack input it into the cons cell structure.
This is something that I'm working towards now, as it is easier for me to understand and I already have implemented a stack in C before, but I know that I can just build the structure recursively, I'm just not sure how. The following is code that I have:
list s_expression() {
list local;
list temp;
if (strcmp(token, "(") == 0) {
strcpy(token, getToken());
[Code] .....
s_expression is supposed to return a pointer to a recursively built cons cell structure. I'm just having issues figuring out when to call getToken(), as I either call getToken in the wrong spot and unintentionally skip over a token, or I call getToken() when I'm done getting all of the tokens, thus causing my program to continue searching for a token from user input instead of continuing on with the rest of the program.
When should I be calling getToken()?
In addition, what would be better, recursively building the cons cell structure as you go through the user's input, or putting all of the tokens into a stack and then building the cons cell structure using that stack?
If needed, I can post the lexical analyzer that's been provided to us. Also, for S_expression(); showing up as S_exp<b></b>pression();, I'm not sure what happened there. I copied this post from my question on stack overflow.
Take for example two arrays.
int A[2][2][2] = { {{1, 2}, {3, 4}},{{ 5, 6}, {7, 8}} };
int B[1]
I want to store the entire array "A" into B[1]. Is it possible?
