the above pyramid looks like a doom.i.e 1-5 will be in center.1-4(L)1-3(L)1-2(L)1(L) similarly 1-4(R) 1-3(R) 1-2(R) 1(R)
I'm partly successful in building the requirement of the program.but cant able to think the logic for the other half. how can i proceed.below is the code written in c#.
Code:
for (int i = 1; i <= 5; i++)
{
//int l = 1;

I need to print like below pattern.

I got the upper pattern but below pattern is not working it executes infinte loop, how to reslove this.

using System.Linq;
using System.Text;
namespace ro {
class ro {
static void Main(string[] args) {
int numberoflayer = 5, Space, Number;
[Code] ....
The user will enter the number of '*'s on the 1st row (ntop) and then the number of rows forming the trapezoid (nrows). (using <iostream>, cout)
For instance, an inverted trapezoid with 7 '*"s in the 1st row and 3 rows forming the inverted trapezoid looks like:
for (i = nrows; i >= 1; i--) {
for (j = 0; j >= nrows; j++) {
cout << " ";
} for (k=ntop; k >= 2; k--) {
cout << "*";
} }
The output is just blank as of now.
I am new to C++ and I want to make an inverted pyramid so it follows the form of:
54321
x432x
xx3xx
or:
7654321
x65432x
xx543xx
xxx4xxx
The goal is to make it look like that pattern. The x's denote spaces. This is only for integers under 10.
#include<iostream>
using namespace std;
int main() {
int n,i,j;
cout << "Enter a positive odd number: ";
cin >> n;
[Code] ....
I am not sure how to add the spaces or make it subtract like the pattern.
I have to Write a program to produce that makes four triangles and a pyramid. I have to ask the user they height of the triangle and prevent the user from entering a height any larger than 25. It should look like this.
Enter the height of your triangle/pyramid: 3

I am trying to figure out how to create a program that will draw a triangle using *'s with a base the has a user-inputted number of *'s like so:
*
***
*****
It needs to take a user inputted number and draw a pyramid like the above pyramid with the number of *'s in the base matching the user inputted number (i.e., user enters 10, so the triangle has 10 *'s in the base). I figured it would be best to first create a loop to draw out the correct number of *'s before trying to create another loop to draw out the correct number of spaces, to properly align the *'s into a triangle shape.

So I have a program where I solve a maze using stacks. So my display_maze function take two parameters and displays the maze according to where the x coordinate and y coordinate are.
I have an error during my move function, as my maze doesn't display for some reason
void Player::player_move() {
Stack stack;
Maze maze;
Lock taken;
// Monster monster;
stack.push_values();
[Code] ....
It should be displaying, because after debugging I discovered the problem isn't with the display_maze function.
So I'm trying to take some information that a user inputs and to then write it into a .txt file. The user would input a student ID followed by 4 quiz grades. I need to use nested loops for the input, a while loop for the outer and a for loop for the inner.
The data in the .txt should would look like:
studentID quiz1 quiz2 quiz3 quiz4
studentID quiz1 quiz2 quiz3 quiz4
etc.
My problem is I'm not sure how to structure the code. I have very few examples I'm working with to understand what I'm working with.
I was developing an exercise program for myself (note: not a project in school) to enhance my programming skills in C++ then I encountered a "logic bug" (that's how I call it :D ) I think. I googled stuffs I need to know and ended up to post my question here.
Here's the scene:
1. When using GetAsyncKeyState I can capture Function Keys [F1-F12, etc..]
2. While doing and having fun to my exercise program, I suddenly noticed that whatever key I pressed from the keyboard {example: asdfkj], it keeps the keys entered and brings to a "field" that accepts user input.
What you should do...
1. Press any key (example: asdfisdjfisdjff) then proceed to press F1. And see what happens. I don't know how to erase what I have entered before pressing F1.
here's the code.
#include <cstdlib>
#include <iostream>
#include <windows.h>
#include <string>
using namespace std;
void gotoxy();
void gotoxy( int column, int line ) {

I'm trying to create program that reads in commands from an input file, and accordingly creates, connects or destroys logic gate primitives (and gates, or gates). Additionally, I'm trying to modify a previous program that I wrote to do this using QThreads, where each gate is placed in its own QThread. I'm trying to avoid using invokemethod, and I'm sure this method can work. My specific issue that I'm having trouble debugging is in my connect code block in main.cpp. Whenever I try to reference a gate specified by the input file that is NOT the true or false gate (I have one of each and they are attached to any gate that needs a true or false input), I get only a NULL reference. This includes attempting to reference the gate in my gatelist QMap. Calling gatelist.value(newCommand.at(1)) causes the program to hang, and the connect statements referencing said gate return errors about connecting a signal or slot of a NULL pointer.
Here is main.cpp:
#include <QPointer>
#include <QMap>
#include <QDebug>
#include <QString>
#include <QFile>
#include <QTextStream>

My issue is regardless of which date I input its always defaulting to the values I have set in my constructor in my implementation file in the else statement. So the values always default to 3/15/2006 I think its something to do with the logic in my bool function but I may be incorrect.

I need to create code based upon the following pseudo code:
dictionary=vector
file containing words to search for=external file
While there more words to search, for search the dictionary if the entire dictionary is searched and the word is not found, return the word, search the dictionary for the next element (and so on)
I cannot for the life of me figure out the sequence of loops to do this. The following code returns all of the words instead of just the ones not found in the dictionary, but it's all I've got after countless changes:
#include <iostream>
#include <fstream>
#include <vector>
#include <string>
using namespace std;
int main() {
string dictword;
ifstream dictionary;
[Code] ....
And it returns every word in the external file.
I can't seem to find the logic error in my perceptron. The perceptron's feedback function pushes back a bias of 1.0 into the input vector, and calculates the dot product of the input vector and it's weight vector, and returns 1 if the dot product is > 0, and -1 otherwise. This will determine whether the inputted point is above or below the hyperplane given by the functor.
The training function instantiates a trainer object , which feeds it a vector random numbers, along with the correct answer (in this case, whether the point is above or below the hyperplane given by a functor). It then calls the feedback function, and subtracts its answer from the correct answer, and updates the weights by adding the input vector to the weight vector, and multiplying the weight vector by the error, and by a correction factor, in this case 0.01.

I am trying to create a NFA from a regular expression. I have a grasp on reading in the regular expression and being able to make a stack from it.

i built a programming language called jade that right now can only print. i want to add variables to it however. I am going to use a modified bajarne stroustrop calculator to handle expressions (ie will now include string manipulations and such), but I want to build a var class into the program to make it easier for the program. i want variables to act like python variabes, and arrays to act like python associative arrays. Ive scoured different containers, but they only work if the variable isnt an array in my language, because it will only have one type. the only thing i can come up with is a union and 4 overloaded = operators (for bool, int, double, and string) is there a better way to do this?
View 2 Replies View RelatedBasically I want to embed the QGIS canvas widget into a custom application. In order to do that, I need to build QGIS from it's source in order to obtain the devel *.lib, *.dll, *.h, etc. files required. To that result, I am trying to build either version 2.6.* or the current nightly build ~2.7 - 2.8 64 bit version. There is very little documentation on the x64 builds. Not to mention that CMake and I are not the best of friends.
My progress so far:
- Successfully built the extremely out of date nightly build readme instructions of version 0.11 x86
- Partial success in creating CMake output to VS2010, but many required headers were not included such as gqsmapcanvas.h, (So even if I got it building I couldn't use the canvas widget in an application)
*Note I updated the external packages to x64 versions, so it is not an architecture mismatch issue.
I have also had issues with QWT looking for QWT Polar header files, but I suspect this is another issue with the missing headers as most of the errors related to files contained in the original source from GIT.
I have been struggling with this program. I am somewhat new to c and suck at logic. I have a personal program I want to make that I will try to get extra credit for in school. I have a printed set of winning lottery numbers form the last 10 years. I chose the easiest one do do logically which is just 5 numbers none repeating.
I am trying to find out how I can print the least common 10 sets. I think if there are any set which have not been picked I would have to print all of those because logically they would all be equal, then print sequentially the sets least picked up to 10.
I have pseudocode which I am sure is wrong but will post it just to show that I am trying. My first attempt was to add the numbers but quickly realized that that wouldn't work ...

Read Nums

I have a doubly linked list from which I need to occasionally delete elements (any elements that have a type value different from 0). The function I have seems to work, but looking at it, I think I could probably make the logic cleaner.

struct Event {

struct Event *next;
struct Event *prev;

In a record I have IDs of type int but some may repeat. These IDs also got sales of type float. I wish to compare the IDs number of times they appear and of match found accumulate their sales and put it in another struct. However if an ID is found which is new I pass it to a function to initiate sales..but my code never reach second ID, given I am trying with two IDs.. given IDs in transFile
ID Sale
12345 870
90909 100
I enter these two in transFile and match it with masterRecord. 12345 is matched and updated likewise but 90909 is never executed or matched in checkID function..

I created a program to convert files to XML. This if statement is giving me some trouble. I am trying to replace all &s with the XML & so that &s will work in the entities of the XML file. Some entities have more than 1 &. With those which have more than one I get an output like this: <cit:district>Anambra & Enugu & Eb</cit:district> .
if(word.find("&") != string::npos) {
word.replace(word.find("&"), 1, "&");

I'm new to C#. I'm trying to create a program to audit some of our processors. As you will see below, I have two foreach loops that allow me access to errorOrders(returns <<UserName, #of errors>>) and totalOrders (returns <<UserName, #of totalOrders>>).
However, the problem i'm running into now is that it seems to constantly loop through these two ForEach loops. When i run it, the 'count' on both errorOrders & totalOrders is 38. The program loops through all 38 users just fine, but then it continues to loop through users again...re-doing the process that it just finished.
I'm looking to see if there is another way I could set this section up so that it only loops through users once. I was thinking about trying to create a 'Boolean flag' that would force the program out of the ForEach loop after it has run through all the users...but i'm sure there are other ways to handle this.
foreach (KeyValuePair<string, int> error in errorOrders)
{
foreach (KeyValuePair<string, int> total in totalOrders)
{
[Code]....
I know i should probably seperate these two foreach loops instead of having them nested..however, the problem that arises once i do that is my errPercentage can not be calculated if i do.
I would like to initialize a N-dimensional matrix by specifying the dimension N.
To be clearer :
if N=2 I use to do that :
std::vector<std::vector<double>> myMatrix;
if N=3 :
std::vector<std::vector<std::vector<double>>> myMatrix;
and so on...
What I would like is to give N as an argument of a function which construct a N-dimensional empty matrix. Is that possible ?
Making/Building 3D Game Engines, Do I need to know anything related to ART or graphics in order to make them ? I mean, I do know that having a know how about vectors is VERY important, But I am no good at art, I suck. I have thought of getting a separate guy to do the art, as I'm more interested in writing code and then implementing it making use of the art that has been made, I'm just worried if I need to or not need to know anything about sketching or art in order to write a 3D Game engine ?
