C++ :: Program To Extract Special Code From A List Of Numbers

Nov 1, 2013

I am a beginner and I ALWAYS have the toughest time doing I/O files. It's extremely frustrating. It "seems" it should be so simple. The program should find a code from a list of numbers. These numbers are from 0 - 9, and after each number is a space in the file. Your job is to extract a special code containing only 10 of those numbers. For the number to be part of the code, it should be divisible by 2. After extracting 10 numbers divisible by 2 for the code, write those 10 numbers to the file to form the expected code.

Input file is ("question.txt")
Output should be ("code.txt")

Should this contain a "for loop" or If/else ?

Here's what I did . .

/
// int numbers, total, counter;
ifstream inFile;
inFile.open ("question.txt");
outFile.open ("code.txt");
if (!inFile)

C++ :: Program To Extract Numbers From A File That Is Always Updating With New Data

Mar 14, 2013

How to write a C or C++ program that extracts certain numbers out of a section after the 4, 5 and 6 space.

For Example:

The output file will produce:

[ [1900 00 0 -2.000000 0.650000 0.006000 0.020000 2.274000 0.010000 54 0 0.7 10.8 1 0 0 0.000000 17.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 18];...

So I want to extract the numbers 0.650000, 0.006000, 0.020000 because those are the 4,5,6 space after [ [

Another problem I have is that the output file I showed will always being updated constantly for instance as follow:

[ [1900 00 0 -2.000000 0.650000 0.006000 0.020000 2.2054000 0.010000 10 0 0.7 10.8 1 0 0 0.000000 17.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 13];...

[ [1900 00 0 -1.000000 0.650000 0.006000 0.020000 2.694000 0.010000 9 0 0.7 10.8 1 0 0 0.000000 17.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 10];...

[ [1900 00 0 -2.000000 0.6023000 0.04000 0.050000 2.2454000 0.010000 5 0 0.7 10.8 1 0 0 0.000000 17.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 12];...

And it will keep updating like this and I want to update the previous numbers I extracted with now the new numbers after the 4,5, and 6 space.

So I have to write a code to let it know when it encounters [ [ start looking for the 4,5,6 space and get those numbers and once it reaches ;... that's the end of that section so re-look for the next section of numbers after the 4,5,6 space.

The file will be a text file or matlab file that is always being updated with these sections of numbers. Can I make this a #include<nameoffile.h> or does .h not work with a file that is always being updated.

C++ :: Code For Sum Of Pandigital Numbers

Mar 25, 2013

I am a database developer and I am assigned with a task to finish it as someone left it in the middle.The number 1406357289 ,is a o to 9 pandigital number because it is made up of each of the digits of 0 to 9 in some order,using each digit only once, but it also has a rather interesting sub-string divisibility property. Let d1 be the 1st digit,d2 be the 2nd digit, and so on.In this way,we not the following;

d2d3d4=406 is divisible by 2
d3d4d5=063 is divisible by 3
d4d5d6=635 is divisible by 5
d5d6d7=357 is divisible by 7
d6d7d8=572 is divisible by 11
d7d8d9=728 is divisible by 13
d3d4d5=289 is divisible by 17.

Find the sum of all 0 to 9 pandigital numbers with this property.

C++ :: Statistics Code - Comparing Two Columns Of Numbers?

Aug 17, 2014

I am wondering if there is some repository of c++ code for statistics comparing two columns of numbers? Statistics are so common now that it seems like with the oo concept of reusable code there should be allot of that floating around. Code that would accept two vectors and generate comparisons like pearson's correlation, root mean square error, mean absolute error, median absolute error, etc would be very useful.

I have looked around some and find some code examples, and other posts basically saying, "Google the algorithm and figure it out yourself." At this point, there should almost be stl classes like the ones for union(), intersection(), accumulate(), and other simpler math functions.

C++ :: Implement Source Code That Turns Numbers Into English Text

Apr 18, 2013

I have been working on the same problem as mp252 from an earlier thread and 4 days later, I appear to have it working. Mine only goes from 0-9999 though as I must move on!

Code:
#include <iostream>
#include <string>
int getThousands(int number);
int getHundreds(int number);
int getTens(int number);
int getUnits(int number);
void printNumber(int number);

[Code]......

I had a scrap of paper like a mad scientist trying to find relationships between numbers and the values that they would return through my functions. This is how I arrived at the conditions of my if statements in 'void printNumber'.

I have seen other code that allows a greater range but I can't quite follow it (yet):

C++ :: How To Make Special Purpose Libraries

There are many libraries in C++, but how are they made?

For example: SDL, SFML, Open CV, STK

There are no special functions in C++ from which we can create such libraries, If I wanted to create a library that processes sound signals, how would I do that? How can I access the mic, speakers and process the signals.

Open CV processes videos but which functions does it use?

C# :: How To Rearrange Lists In A Special Manner

May 15, 2014

how to rearrange lists in an special manner.

I have heard about the hashset but I do not fully understand how that thing works or if it is the best option for this issue.

Basically I have 3 lists: LIST1, LIST2 and LIST3.

LIST1 is a set of xyz points and LIST2 shows how the points are connected (clockwise, counter clockwise, coolinear).

For example the fact that in the first line of LIST2 appears 0, 1, 2,-1 means that the points in LIST1 are connected as follows:

(0 0 128.588459085565)->(25 0 134.979628462965)->(0 0 134.979628462965)

Same for line2 of LIST2: 1, 4, 2,-1

(25 0 134.979628462965)->(25 0 140.100717207301)->(0 0 134.979628462965)

etc...

The value -1 at the end of each line does not mean anything but I need to keep it.

Finally LIST3 tells me if the points are connected counterclockwise (-1), clockwise (1), or coolinear (0).

The thing is that I want to get things as follows:

If the values of list 3=1 then I need to extract all the points in the list 1 that correspond to the value 1 in order. However the values in LIST2 cannot keep being 1, 4, 2,-1 they need to be reorganised starting by zero. Expected result in LIST2= 0,3,1,-1.

We need to do this for each value in list3 (1,-1 and 0).

The idea is to get 3 groups of values:

- Group 1 including all the values that are clockwise (list3) with the points in order in list1 and showing connections starting from zero on in list2.

- Group 2 including all the values that are counterclockwise (list3) with the points in order in list1 and showing connections starting from zero on in list2.

- Group 3 including all the values that are coolinear (list3) with the points in order in list1 and showing connections starting from zero on in list2.

The idea is to be able to print 3 files in the following way:

FILE1:

Points which are clockwise in LIST 1
...

Connections of those points in LIST 2
...

FILE2:

Points which are counterclockwise in LIST 1

C++ :: Verifying If The Number Is Special And Not Scary

Feb 22, 2012

Code:

Exercise. 1.5 A number is special if it is divisible (no remainder) by 15. A number is big if it is greater than 999. A number is weird if it is divisible by 5 and 6 but not 18. A number is scary if it is big or weird.

Write a program to check which of the following, 450, 540, 600, and 675 are special but not scary.

Declare four variables called special, big, weird, and scary and make suitable assignments to these variables as a number is tested.

I want to do it with a function, but it just output that everything is Special and Scary, and that everything values 4199536.

Code:
#include <stdio.h>
#include <stdlib.h>
/* Function */
int test(int);
int test(int a) {

Visual C++ :: Grab Special Lines From A File

Time : xx:xx:xx
Time : xx:xx:xx

So, I want to grab lines that start with "Time : " and put them inside a list<string> for later use. I am using windows so I don't know if the newline character is '
' or '
' also I don't want my grabed line contain any special character.

I have this code, but didn't work well because some special characters remain inside the string.

Code:

string buf;
list<string> ls;
ifstream read("test.txt", ios_base::binary);
while(!read.eof())
{
