I'm wanting to create an image, all I need is to be able to set RGB values and X-Y coordinates, I'm not wanting to read or manipulate images. Any easy to use library or another simple method of doing this?

This (2)original list is then to be printed out. The program then uses the algorithm "bubble sort" to (3)order the list in descending order before finally printing it out again.
I have managed to do this but I kind of cheated since I do not quite understand how to manipulate a linked list. What did was I took the values in the linked list and transferred them into an array and then did bubble sort on that array.how to do bubble sort on a linked list as well as how to print a linked list.
Code:
#include<stdio.h>#include<stdlib.h>
typedef struct node
{
int info;
struct node *link;
}Node, *NodePointer;
void printList (NodePointer head)

My code is supposed to read a five to four digit code of a resistor from a file and determine the resistor's nominal, lower and upper tolerance values. I have inputted my file's first resistor code as a string so I could run tests on it but the problem that occurs is that a get the wrong values from my switch-case statements. I have put printfs after the function call to see what the values were and they turned out wrong. If I could get my return values to be right then I could be on my way coding.
#include<stdlib.h>
#include<stdio.h>
double bandNum(char x); // function prototype that will read the resistor value for the first, second and possibly third band
double bandMult(char x); // function prototype that multiplies the resistor by some value of 10
double bandTol(char x); // function prototype that the tolerance of the resistor is multiplied by

My program works fine in all areas but adding the average every loop. It gives me a weird -1.#IND as an output, and it's supposed to calculate the total mileage each time I enter new values per trip.

I am trying to create a simple interface on console to allow to input some values to some variables. For ex:

However, I want these three to display at the same time (now they display one by one), and in the console window I can move the cursor between input place of a, b and c with "arrow key" of keyboard.

I can't figure out why my makeString gets called first and the pString its called with contains garbage. I want my allocateMem to get called first, but my program is not going to that. What is wrong with the order of my code?
Why my calculate function is producing a zero?I feel like it may have something to do with there being zeros the arrays it takes. The arbitrary cout statements are just for my debugging purposes. Input is formatted as follows:

Something is wrong with option 1. For some reason it adds 1, 2, 3, 4 ... 5 onto the output and I can't think why. Here is a screenshot.

I have done some programming or rather have written and implemented some algorithms in code (is there a difference? :-)) but am having some teething problems with a project I am currently working on.
To start with I am simply reading in the data from a .txt file into a vector. This is the code that I currently have:
Code:
#include <iostream>
#include <fstream>
#include <cerrno>
#include <vector>
[Code]....
This compiles fine but currently outputs a different integer everytime I run the program. I can remember having this problem when I started coding before using a different language and if I remember correctly it was quite easy to resolve. I thought it was because I had missed off the 'return 0' but it is something similar I think.
In my program I am supposed to call isEqualTo with a user defined class type, and print out if my two numbers being compared are equal or not. I had to write two versions of this, one with just a template which works fine, but when I implemented the class, all the sudden my program just spews out true no matter if actually equal or not. Here is what I have so far:
#include "stdafx.h"
#include <iostream>
#include "UserClass.h"
using namespace std;
template<typename T>
bool isEqualTo(T value1, T value2){
if (value1 == value2)

My test file consists of several characters and digits. Nothing special and I at this point in time do not have any type of formatting that needs to be adhered to. I am simply wanting to read the file character by character and print it out. When I run the program, I get this symbol:

Code: printf("%s

I get a segmentation fault.

I'm attempting to save values from a char buffer into integer values of a struct.
This is what resides in the buffer "STD 2 2 2 2 2 2 2 " and this is my sscanf call
Code:
sscanf(buffer, "STD %d %d %d %d %d %d %d
", &dt_struct.date,
&dt_struct.mth,
&dt_struct.year,
&dt_struct.dow,
&dt_struct.hr,
&dt_struct.min,
&dt_struct.sec);
I then print the values back out in a string using sprintf.
Code:
sprintf(t_string, "STD %d %d %d %d %d %d %d
", dt_struct.date,
dt_struct.mth,
dt_struct.year,
dt_struct.dow,
dt_struct.hr,
dt_struct.min,
dt_struct.sec);
But this is what I get:
STD 0 0 2 0 0 0 2
Instead of what I want:
STD 2 2 2 2 2 2 2
I've been working on a homework assignment that randomly generates integers and populates them into an array (array1). The program is then supposed to:
1.) copy those values to a second empty array (array2)
2.) sort the values already in array1 (using an inline function)
3.) enqueue the unsorted integers from array2 into a heap vector
4.) a third empty array (array3) is supposed to be populated with those unsorted integers (by dequeuing them from the heap), sorted in reverse order.
But no matter what I do, I always get garbage values like these:
I've tried using both a standard random number generator:
array1[i] = rand()%100+1;
And the d_random.h file my instructor gave us, but nothing works.
Here's the code from all 3 files:
HeapTester.cpp
Code:
#include <iostream> // Provides cin, cout
#include <cstdlib> // Provides EXIT_SUCCESS, rand, srand
#include "d_random.h"//Provides random number generator
#include "Heap.h"
using namespace std; // Use C++ Standard namespace
//Elements in each array.
const int arrayLength = 15;//100;
[Code] ....
Why I'm getting those garbage values?
I was wondering if this was even possible and if so, how do I do it.
else if (speech.ToLower().Contains("truck") && speech.EndsWith(number))
{
Here I would like to see if my speech had ended with any of the values i would have stored in the string "numbers". If it did, I would like to just take the value and add it to a new string called whatever
}
I have tried this a million different ways and I cant get it to work. I'm not even sure how I would go about storing tons of different numbers in one string, or if that's even possible.
I'm having some problems with implementing an AI. It should be just a simple AI that follows player. Here is the code that I got so far:
(float)DirectionX = Circle->GetX() - AI->GetX();
(float)DirectionY = Circle->GetY() - AI->GetY();
(float)Hyp = sqrt(DirectionX * DirectionX + DirectionY * DirectionY);
DirectionX /= Hyp;
DirectionY /= Hyp;
x += DirectionX * 3;
y += DirectionY * 3;
This is what I got so far. It creates a vector in a direction I want to move, then just normalizes the vector. Simple as that. But I'm having 2 problems..
AI moves towards player only when Im at like the end of screen and the AI is on the other side, I must keep a certain distance for it to be able to move towards me. Basically, its not constantly moving towards the player. I also tried it with trig, using atan2 for angle and sin / cos for speed. Also didn't work, same result.
The other problem is when I want to add i.e 5 more AIs. For each new AI it creates, it makes a new update.. So, to kinda clear it up. If I'm in middle of the screen and an AI is spawned above me, it will move towards me. But when after that one, 2nd AI spawns beneath me, both 1st and 2nd AI move up. Basically, previous AIs take the update from last one that is created. For updating I'm using lists, objects and iters.

View 2 Replies View RelatedI tried to write a simple program to calculate monthly yield, APR, and principle in various directions. Anyway, here's some code to get the APR from the principle and monthly yield. When I run it though, it spits 0 at me every time!

Here is the offending function:

I am writing a simple file parser for use in another project (for config file). The trickiest thing seems to be skipping unwanted characters (comments, spaces). It works partly, but after the second line of an inputed file processes only the first three characters.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define TEXT_FILE "data.txt"

NOTE: Currently I am just trying to process and remove unwanted data, the actual processing of extracted data should be much simpler.
So im just trying to read in an pgm file and store it in an array,
Code:
int** imageArray;
//allocate the image array
imageArray = (int**) malloc(row * sizeof(int*));
for(i = 0; i < row; i++)
imageArray[i] = (int*) malloc(col * sizeof(int));
[Code]....
It stores about 1/3 of the file into the array, and then starts printing 6815940 6819608 followed by a bunch of 0's.
