C# :: Histogram - Identify Integer In Array And Insert Symbol For Every Single One
Apr 18, 2015
I am supposed to make a histogram. I succeeded in generating the integers for the histogram. But what I want to do is instead of displaying numbers in the console, I want something like "*" displayed for every integer there is in an array. It should look something like this.
*
****
*****
********
**********

As far as I understand, in some way I need to identify the integer in the array and for every single one of them I need to insert the symbol. I don't know how to identify it.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1{
class Program {
static void Main(string[] args) {
diceHistogram();
[Code] .....

Identify the invalid C expression or choose "all are valid". Assume all variables are integer and non-zero.
7.
a) a+b-0 b) c+-a%4 c) xm6-24 d) xf3r6+2
e) all are valid
8.
a) xx+yy%zz b) z%(z%z%z)) c) ha+ha+ha d) x23-20.4
e) all are valid

Write a program that reads four integers from a file ‘input.txt’.
The program will then create a single integer number from the four integers. The output of the program will be the single number and single number + 600.
#include <iostream>
using namespace std;
int main () {
int number , a;
cout<<"enter en integer number";
cin>>number;
cout<<"add 600 to the number"
cin>>a=number+600;
return 0;
}

I have a multidimensional array that runs parallel with a string array
Lincoln 120 300 400
Parks 100 500 250
Shakespeare 0 30 50
Ghandi 250 100 40
Ashe 300 50 175
Rodriguez 87 118 320
Curie 284 0 112
I need to sort this and I know how to do it. But I need to sort it again with the highest value in the first row and keep all information in that row paired with the name . So
Lincoln 120 300 400
Parks 100 500 250
Parks 100 500 250
Lincoln 120 300 400
I need so swap this whole rows. I'm using dynamic array. So my question is Do I have to do a bunch of temps to move them? Or is there a way to move the whole int array row as a single unit?

I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet
Code: uchar uc[100];
for(i=0;i<100;i++)
{
uc[i] = i;
}
The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.

I wrote a code which checks if there are any single numbers in an array.e.g.In the next array there is a single number - "3" 4 1 4 3 4 1..Here is an array which doesn't have single numbers in it: 4 1 4 3 3 1
Code:
#include <iostream>
using namespace std;
int single (int arr[], int size)
{
int couple=0;
[Code]....
First I thought to double the number of couples I'll get from my search and find some connection to the length of the array, but it hasn't worked out (signed red).

I am trying to read in player names (ex: first last) from a text file into the people[].name data struct. I can successfully read in my card file, but I cannot get this to work. I get a seg fault. I believe this is because nothing is actually being read in for my while loops. I can't use std::strings so these must be c-style strings aka char arrays.
// deck of cards
// below are initializations
#include <iostream>
#include <fstream>
#include <ctime>
#include <stdlib.h>
#include <string>
using namespace std;
//globals
const int maxCards = 52;

I wanna write a class for polynomials, but there are some bugs in my code. I want to identify a polynomial with two arrays of the same length, one that contains the exponents of the nonzero monomials, and the other that contains the coefficients itself.
for example: (shematically)
3x^2 +5x^100 shoud be identified by array1=(2,100) and array2=(3,5)
the size of that polynomial should be Dim=2.
it should be possible to change the size dynamically.
Code:
#ifndef poly
#define poly
#include<cassert>
class poly {
[Code] ....
PROBLEM1 the destructor isnt working:
virtual ~poly() {delete [] start;delete [] koef;} //destruktor
Error: This declaration has no Storage class or typ specifier.
Error: Expected an identifier.
PROBLEM2 the constructor isnt working:
poly::poly(int x=0)
Error: Expected an identifier
Error: Expected a )
Error: Expected a ;.
I dont know what the computer want to tell me??

I want to implement some "debugger like" tool (very limited one, just identify at running time the current stack trace, and print messages from the user) on some code that the user wrote. what I get from the user is a function name (in the beginning of it's declaration), and when the user want to print some message he uses some print macro I should implement.
My target is printing the stack call, and all the messages that the user wrote, in the right place on the running place.
By what c++ feature can know on running time that a specific function code has ended??
Its easy to push a function to some vector when it called (since I get its name from the user), but when it ends and return to the function called it...

We know that function pointer for virtual function are stored in a vtable.When we have multiple function pointer entry in vtable and we call one of the virtual function then how the corresponding or correct function pointer is retrived from Vtable? Who do this stuff? In assembly code i can not see any code or logic to detrmine the correct function pointer.

I have a dialog app with two separate static controls. Both controls have been subclassed from CStatic derived class to implement drag and drop and double clicking. The class works just fine, but I cannot figure out which of the controls is being double clicked or dragged and dropped onto because I only have the code below operating. I need some method in the derived class to determine which control is being manipulated.
Code:
// header file
#pragma once
#ifndef __AFXWIN_H__

I'm trying to code one of the problems but it really is hard to catch errors for a novice like me at first.
I have to Write a single C function for computing the histogram of a list of nonnegative integers into 4 bins.
The main() function first initializes a positive integer array called List of size N, takes 3 inputs from the user A, B, C (assume 0 < A < B < C), and declares a second integer array Bin[4].
The doBinning function should count the number of elements of List in the interval [0, A) and store it in Bin[0], count of [A, B) in Bin[1], count of elements in [B,C) in Bin[2], and the number of elements >= C in Bin[3]
Code:
#include <stdio.h>
#define N 10
#define M 4
int *doBinning (int source[], int dest[], int a, int b, int c);
int main (){
[Code] ....
Somehow I keep getting error from ptr = doBinning(List[], Bins[]. What am I doing wrong? Code might contain some errors.
