I am trying to get this to work without arrays. At the moment all I am trying to do is allow it so that when the user presses 1 the board prints with 1 replaced by X, tell me where am i going wrong. I know its not finished.
#include <stdio.h>
#include <stdbool.h>
char a = '1';
char b = '2';

I'm trying to write a code that proves a queue like fifo (first in first out). I have four characters :
p(rint),e(nqueue),d(equeue) and q(uit).
The problem is when I press d a first character must get rid of, but not. When I press d the numbers get double.
Example input:
e 2 3 9 8 7
p
2 3 9 8 7
d
p
3 9 8 7
d
p
9 8 7
#include <stdio.h>
void enqueue(int queue[], int newnum, int *tail_p, int maxsize);
void deque(int queue[], int *tail_p, int *elem);
void printqueue(int queue[],int count);

I have a sword(25 damage), spear(20 damage), arrow(15 damage), dagger(10 damage) and knife(5 damage). I want to make a class for them so that I can equip one of them in battle and use them to inflict damage.
View 1 Replies View RelatedI define "Comwords" as a string, but apparently it takes the members as chars, then I can't set strings in a structure equal to the chars.
I see to also be having unknown problems with the ComMAL array and loading it values into another element of the same structure.
How to correct this? I was thinking of casting char elements as strings, but could find no reference in my library book regarding how to do that (lots on casting int's a doubles...)

Using a for loop, construct two 100 element arrays, x and y, such that element i of x stores the value sin(2*pi*i/100)) and the corresponding element of y stores cos((2*pi*i/100)). Print the values stored in the elements of x and y as you calculate them.
I have attempted to solve it but I'm not sure why the value 0 is only being printed, maybe I haven't assigned sin(2i/100)) and cos((2i/100)) to the arrays properly?

Here's my game, what do I need to learn to make a basic GUI? (Easiest way possible for now).
--NOTE, the code was a bit too long for me to post. I can add it if it is necessary. Basically all I want are 4 buttons on the main screen, one that says "Arena," "Store," "Stats," and "Exit."
There will of course be sub menus to each option, but we will get to that later.
I have project that is on c++. it runs fine. i want to use it in my C# application as a dll. i have created its dll and but firing exception of "interprocess communication".
Is this a doable task that creating dll of an exe project and using it in C# application?
So I tried to find some youtube videos on how to make a DLL, I found one, I also found several topics (like on msdn and stuff), but I have this code

error LNK2001: unresolved external symbol "private: static void * PathSocket::hIDTask" (?hIDTask@PathSocket@@0PAXA)
WHY is there static, and what does dllimport/dllexport does? also there are NO tutorials with variables inside dll >.<
I've been following this [URL] ..... and the video I already lost, however there's no
#ifdef MATHFUNCSDLL_EXPORTS
#define MATHFUNCSDLL_API __declspec(dllexport)
#else
#define MATHFUNCSDLL_API __declspec(dllimport)
#endif
in the video, why do we have to use that? [URL] .....
int arr[4][5];
for (int(&row)[5] : arr){
for (int &column : row){
} }
Why do we name it row instead column?
int arr[row][column]
Wouldn't this be like
int arr[4][5];
for (int(&column)[5] : arr){
for (int &row: column){
}
It just seems funny to me because we use row[5] which should be 4 if we meant row? Or did I read it wrong in C++ prime !?
So basically I have to write a C program that, when opening the html file in a browser, looks essentially like this: (Size, position, color of the shapes doesn't matter so long as I have one of each shape and the box surrounding them. Words up top dont matter either.)

#define FILENAME ("A4P1.html")

One exercise says that, "Define a right triangle class. Make an octagonal shape out of eight right triangles of different colors."
Making such a class isn't difficult. I wrote it as follows:
#include "Simple_window.h"
class right_triangle : public Shape {
public:
right_triangle(Point p, int l, int sh): c(p), _long(l), _short(sh)

But it sounds that making an octagon using eight right triangles isn't possible!

I wish to create a simple animation, similar to the pong game but completely automatic (i.e. both sides play against eachother sort of like in a screensaver of sorts).
I am clueless on to even start tackling this, what tools to use and how to use them, to make them do what I want. I have had some experience with C++ scripting while modding Fallout 3, but I'm not sure how similar the scripting system available in the SDK for that game, is to the real thing.
Like I was saying I want to create a simple animation where two AI blocks try to prevent a ball from reaching the wall behind them.

What my ultimate goal here is to make a program that asks the user how many numbers they would like to add followed by asking the user what numbers they want to add. I want the amount of numbers they can add to be infinite and have the loop continue adding the numbers until it reaches the final number. I just need to know how to do this.

View 4 Replies View RelatedI have a 2D array, array[20][3]. Each row represents a storm and each column represents month #, wind speed, and pressure in that order. This data is read from a file and auto-fills the array. I need to be able to give users the ability to add an additional storm or delete a storm. I know that a linked list would be the best approach but I'm not very familiar with linked lists.

I am using an accelerometer and a gyro as sensors.
I am just really confused when it comes to programming in a PID loop to actually use feedback from the sensors to control the motors.
I sort of understand what needs to be done concering PID loops, just i dont know how to do it.
Here's what I have to do: Using strcpy() pass it two strings of characters (such as a name like John Johnson) and copy the second string into the first, in reverse order, and print both. Write a main to exercise your function and to illustrate that the function is working properly.

The plan is to add a new method 'resize' where a new array will copy the contents of the first original array and modify the already existing 'add' method to call 'resize' when necessary.
Up till now, in the constructor I created the new array, should I give the array a default value?
