C :: Why The Numbers Keep Repeating
Jul 8, 2014Well I've given myself a lil project and I can't seem to figure out why the numbers keep repeating. What is the cause of this repetition. the function that generate the numbers is below
Code:
void numGen(struct Ticket *pick){
int x;
int y;
int check = 0;

C :: Generating Random Numbers Without Repeating?
Sep 20, 2014Inside my loop is this
srand(time(NULL))
a=rand()%10;
So it will generate numbers again and again as the loop goes on but it always repeat some numbers. My question is, how would you generate numbers without repeating? Somebody told me that i have to use auto increment, but i really have no idea about that.
C++ :: Build Min Heap With No Repeating Values
Jul 10, 201310,11,20,1512,22,24,19,22
i want to write a c++ program to build min heap which gets above values from user. remember this program should not alloduplicate values to enter. it should discard duplicate values.
C/C++ :: Non Repeating Binary Pairs Of N Values
May 19, 2014I am working with cart algorithm and i have the following problem,i need to try all possible splits of n values in order to determine the best.
So lets say i have 3 values("low","medium",high) then the possible splits(pairs) would be:
(assuming low=0,medium=1,high=2)
0,1-2 low,medium-high
1,0-2 medium,low-high
2,1-0 high,medium-low
For 4 values(a,b,c,d) it would be:
ab,cd
ac,bd
ad,bc
abc,d
adb,c
adc,b
bcd,a
Problem is i dont know n so the solution must be recursive. The possible splits are 2^(n-1)-1. I am really stuck and most of the code is complete for cart and i really don't want to restrict it to binary values.
C/C++ :: Remove Repeating Numbers In Array?
Nov 14, 2014Question was:
QuoteWrite a program that reads in ten numbers and displays distinct numbers. If a number appears multiple times, it is displayed only once.For example: if user enters 1,1,2,3,4,4,5,1,0,9. You should output: 1,2,3,4,5,0,9. Order doesn't matter.
Steps:
a. Create an int[] to hold all the integers of user input and another int[] to store the distinct numbers.
b. Make a nested for-loops which the outer loop goes though the first array and inner loop to check if the value is already inside. Store the value to the second array if new number,otherwise do nothing.
c. Make a for loop to print out the elements of the second array
Visual C++ :: Random Lists Repeating
May 27, 2014So I wanted to make a program which randomizes a list letters or something without repeating the letters like I get here:

Last time I came to you all with an error it was a simple brain fart on my part but I don't think this one is like that. I would love to tell you what the program is supposed to do but I still do not really know, which might be part of the problem. I guess it outputs different sized rectangles...
C/C++ :: Compare Two Arrays And Print Out A List Of All Songs Without Repeating
Mar 11, 2014I have two arrays:
const char *mymp3list[15] = { "Song 1", "Song 2", "Song 3", "Song 4", "Song 5", "Song 6", "Song 7", "Song 8", "Song 9", "Song 10", "Song 11", "Song 12", "Song 13", "Song 14", "Song 15" };
const char *myFriendsmp3list[20] = { "Song 1", "Song 2", "Song 3", "Song 4", "Song 5", "Song 6", "Song 7", "Song 8", "Song 9", "Song 10", "Song 11", "Song 12", "Song 13", "Song 14", "Song 15", "Song 16", "Song 17", "Song 18", "Song 19", "Song 20"};
And I want to compare the two arrays and print out a list of all the "songs" without repeating any.
I've figured out how to print the just the duplicates using:
for (int count = 0; count < SIZE1; count++){
for (int i = 0; i < SIZE2; i++){
if (mysonglist[count] == friendsonglist[i])
cout << mysonglist[count] << "";
}
}
But I'm stumped on how to print a full list containing no duplicates.

Nov 10, 2013I have to optimize a code for below scenario. I am reading stdin (a file redirected to stdin) character by character. How many chars are going to come is not known. After every few chars there is a seaparator. e.g $ as below
rhhrkkj$hghjhdf$ddfkrjt
While reading, if the separator arrives I'm processing the string stored before that separator and then continue reading stdin in same fashion, till EOF. I am using getc(stdin) to read chars.
Using gprof I can see most of the program time is spent inside main() , for this reading logic. Rest of the program is just some insert and search operations. I am getting time of 0.01 secs at the moment, want to reduce further.

View 1 Replies View RelatedC++ :: How To Read TXT File Character By Character
Oct 6, 2013In my program, I'm supposed to read a text file (the name of which is given to me as a command line paramater, as long with an integer), and display the text in a specific format (each line can only be as long as the integer). However, I'm having trouble even reading the text file. I don't know the syntax. I'm only allowed to edit the function that does the formatting, and the code in that is
void typeset (int maxWidth, istream& documentIn)
I don't know how to 'read' the file, as most examples online are ifstream, or openFile or something like that. What I want to do is just read the first character of the file, and continuously keep reading characters until the end of the file.
C/C++ :: Replacing Character In String With Another Character
Sep 13, 2014So I'm trying to create a function that replaces any instance of a character in a string with another. So first I tried the replace() string member function:
In my implementation file
void NewString::ReplaceChar(const char& target,const char& entry)
{
this->replace(this->begin(),this->end(), target, entry);
};
Main program
#include "NewString.h"
using namespace ...;
int main()
[Code].....
Instead of replacing the the l's with y's it outputted a long string of y's. Also, NewString is derived from the string class (it's for the assignment). the header and whole implementation file, already tested.
I've also tried, instead, to use a for loop in ReplaceChar() but I need to overload the == operator and I don't know how I should exactly:
bool NewString::operator ==(const char& target)const {
if(*this == target)
return true;
[Code]....
I want the == operator to test if the value in the char array is equal to target but I'm not sure how to pass in the position. I'm guessing the this pointer in ReplaceChar() is not the same as the one dereferenced in ==() because target is never replaced by entry in the string.

C# :: How To Show A Frame Of Gif
Jan 10, 2015I want to show a frame of a gif image. I searched and found that the following code should work, but it doesn't work. it detects the number of frames correctly but it shows the whole frames of gif instead of the specified frame.
Image[] frames = new Image[36];
Image GG = Image.FromFile(@"C:UsersAdministratorTEST C#TEST2frame2chef.gif");
FrameDimension dimension = new FrameDimension(GG.FrameDimensionsList[0]);
// Number of frames
int frameCount = GG.GetFrameCount(dimension);
label1.Text = frameCount.ToString();
// Return an Image at a certain index
GG.SelectActiveFrame(dimension, 1);
frames[1] = ((Image)GG.Clone());
pictureBox1.Image = frames[1];
C/C++ :: Show All Subset Of A Sub?
Feb 6, 2014A program is a set of all subsets of this part of the show. Users can enter a number., For example, if n = 2 the output looks like this:
{}
{1}
{2}
{1,2}
or for n=3 we have:
{}
{1}
{2}
{3}
{1,2}
{1,3}
{2,3}
{1,2,3}
meantime this program should be solved with tow way. recursive function and Non-recursive.Can also be used in solving the problem of bitwise operations.
C :: Can't Show The Proper Float Value
Jul 7, 2014I am working from my "ansi c" book by steven lawlor, page 73 program 2. write a program that accepts two numbers from the keyboard and prints the following information.
variables
first
second
execution
First number ? 7
Second number ? 2
the second goes into the first 3 times
with a remainder of 1.
the quotient is 3.5.
Code:
#include <stdio.h>
main() {
int first, second;
scanf(" %1i %1i", &first, &second);
printf("First number ? %1i
[Code] ....
//I included this as I had some error message come up
// before, not sure if this is correct though?
} it shows what is expected but I cant get the 3.5.
I have tried %f and variations of width/precision but still not luck. Also, when I click on the application and put in the variables I press enter, the program executes and disappears so I cant see the result. how do I get the program to stay up until I want to get rid of it?
