C++ :: How To Manipulate Certain Strings - Ignoring Spaces
Aug 11, 2013
How I can manipulate certain strings. This program here is supposed to randomly scramble any word/sentence input. However, I notice that even the empty spaces get moved; is there any way to stop that from happening? I would want the empty spaces to stay in their input positions.
#include <iostream>
#include <string.h>
#include <ctime>
#include <cstdlib>
#include <fstream>
#include <string>
using namespace std;
[Code] ....

It should report whether or not, ignoring case, they are the same.
#include <stdio.h>
#include <string.h>
using namespace std;

I have a problem who must print the sentences who have lenght more than 20 characters. I dont know why, but it prints just the first words. Look what i made.
#include<stdio.h>
#include<conio.h>
int main()
[Code]....
For instance :
Give the number of sentences : 3
First sentence : I like the website bytes.com
Second sentence : I like more the website bytes.com
Third sentence : bytes.com
After I compile the program it should print the first two sentences.

I need to write a program that reads a paragraph from a file (i dont know its length) and i need to read it with spaces
i thought of using getline() function but there were problems:
1) how to detect End Of File
2) how to use getline while reading from file
and thought of reading one character at a time but it didnt read spaces

I'm using a Windows.System.Forms.Webbrowser and the document text contains
...<style type="text/css">
Table {
page-break-after: always;
}
table:last-of-type {
page-break-after: auto
}
</style>...
As soon as call ShowPrintPreviewDialog() to show the print preview dialog, it appears to be ignoring
table:table:last-of-type
because the last page in the document is blank.

Now, I have an assignment in which I am to accept arguments from the command line and copy them into a cstring and display said cstring unmolested. Then I should store it into another cstring but ignore all punctuation, spaces and capital letters. Like this:
./a5 Marge lets Norah see Sharon's telegram
As is: Marge lets Norah see Sharon's telegram
---->: margeletsnorahseesharonstelegram
<----: margeletsnorahseesharonstelegram
Sequence entered is a palindrome
=======================================================
Finally I am to chaeck to see if it is a palindrome. Most of it works and if no spaces are entered nor punctuation it works. However, punctuation causes it to malfunction.
char *FormSeqProc (int argc, char *argv[], char seqAsIs[]) {
int len = 0,
n = 0;
for (int p = 1; p < argc; ++p) {
len += strlen(argv[p]);

I need to ignore negative values in an array, but not exit the function.
For example if the user enters:
1,2,3,4,-1,-2,0
the array would be
[1,2,3,4]
Is there a way to ignore these values?

The while loop is increased by i++ each time. In the commented line I want to express.When:
i = 1 , player1.cards[j] = random;
i = 2 , player2.cards[j] = random;
void cardScramble()
{
int random;
int i = 1;
while (i <= 4)

I tried to define it or manipulate it as a string but didn't work.

My program had a requirement to ignore an input beginning with a # sign. The input is entered by user from keyboard. I wanted to know how to use cin.ignore to achieve this.
#include <iostream>
#include <algorithm>
#include <string>
#include <iomanip>
#include <limits>
#include <stdio.h>
using namespace std;
[Code] ....
The output:
Enter the string
# Comment
This is the # comment string.
Answer:
This is the string.

I've come to a point where I want to manipulate an image file at run time or with pre-determine sizes and have to be applied when the windows is moved or through in program options.
I know I can do the applying part. However I am a little unsure of how to tackle the image manipulation. I want to make it so that it is not os dependant. So I know I can not rely on any os functions. The only other thought that came to mind was to deal with the video card itself.
So the main question after all of that is said and done. How is c++ able to interact with the video card directly for images? Or if there are existing function I can use. How do they do that? If I can use existing function I would like to be able to manipulate it myself.

I need a translate (in both directions) all primitive types, into char[] (will be stored in string)
I understand how to manipulate integral types with bits and I cant just cut them down and shift them, but float and double don't work with this manipulation. So, how I can create a perfect bit copy of float and double?
int i = 0xFCED03A4; //Random number
char c[4];
c[0] = ((i >> 3) & 0xFF);
c[1] = ((i >> 2) & 0xFF);
c[2] = ((i >> 1) & 0xFF);
c[1] = (i & 0xFF);
[Code]...
This is basic stuff but I need an equivalent for float and double types, and it needs to be a perfect BIT copy, not value copy.

My random number generator isn't working properly. It seems to be ignoring my conditions when it compiles and I enter the input. The program is supposed to accomplish the following.
1. Let the user input how many digits he or she would like to have in the random numbers.
2. Let the user type in how many of the numbers that he or she wants.
3. It will then generate the numbers.
4. It will display the minimum or maximum number it can be with the number of digits the user entered. And display the number of numbers that the user wanted. It also is supposed to check and output only up to the max of that digit range.
so if someone entered they wanted a digit of 1(1-9) but said they wanted 300 numbers it would only output 9
Example:
the user says that she would like 3 digits to be in the numbers generated. So it will output numbers between 100 and 999. then the user says that they would like only 3 random numbers. So it will output three random numbers in between 100 and 999. Also all of the numbers need to be unique so they can't output more then one of the same number.
I am not sure why but it ignores my conditions. Ill type that I want 7 but it just outputs a bunch of random numbers. it dosen't stay in the ranges.
Class file.
Code:
#include "stdafx.h"
#include <fstream>
#include <iomanip>
#include <iostream>
#include <string>
#include <conio.h>
#include "TargetGen.h"
using namespace std;

I'm trying to write a program that manipulates a doubly linked list. My professor wants it to have two structs, one called Node (containing the data, and pointers to the next and previous nodes) and one called DLList, which contains the nodes for the head and tail (which is then passed to all of my functions).
I'm a little confused how to access the head and tail, for instance, if I want to initially set them to null in the main function (he emphasized the need for this), or to use them in my functions. I've tried a lot of variations to call the head and tail, but I keep getting told that head and tail are undeclared in the function.
How might I access my head and tail, for instance in a main function, when they're defined like this? (I took out all of the logic in my functions for clarity)

Essentially what I need to do is take a text file, ("input.txt"):
4 4
1 0 0 1
1 1 1 1
0 0 1 0
0 0 1 0
And take the first two values on line 1 (4, 4) and use them as length and width.
Number of rows: 4
Number of columns: 4
Then I need to print out the matrix and further manipulate it. I need to find the sum of the 1's per column and then take that number and replace each 1 with the 1's in each column.
So it'll look like this:
2 0 0 2
2 1 3 2
0 0 3 0
0 0 3 0
The part that's mostly troubling me is that my instructor will be giving me the input file with random values, so I don't know what the matrix dimensions will be.
I can read the 2D array but can't seem to use it after. I need to find a way to skip the first line, and then read in the matrix and be able to use it mathematically to add up each column.

I made a program that can use a function to manipulate data from a list class. The program is very basic and I think the error makers may be obvious to some of you. I just wanted to find it without having to scrap my program. It doesn't generate a compile error but it announces a memory error while it is running. I use visual studio 2012, the program is an exercise from a c++ book.
list.h
#ifndef LIST_H_
#define LIST_H_
typedef double Item;
const int MAX = 10;
class List

Create an application to manipulate an array of student record objects. A student record will consist of a name (first, middle, and last), an ID number (9 numeric digits, cannot be more or less), an address (street, city, state, and 5 digit Zip code), and a phone number (3 digit area code and 7 digit number). The application will support an array of students. The user will be allowed to enter records from the keyboard, sort records by either name (last, first, middle) or by ID, save the records to a disk file (name supplied by user), and read the records from a disk file (name again supplied by user).
Create a fixed length string that must check that the length of the string is the required length. The fixed length class should be done as a template with the number of characters as the template argument. From this fixed length string, derive a class to hold digits of a fixed length.
Create component classes as necessary to use together to implement the student record class.
Use either the array template created in an earlier lab to handle the array or you may use the vector class from the STL to handle the array of student record objects.
The maximum number of students will be 25 (it may be less).

So I have to make a program that allows the user to enter both positive and negative numbers and the program is suppose to calculate the sum of only the positive values while ignoring the negative values. Also it is to be a sentinel-controlled loop with a number ending the set of values.

ignoring negative numbers when I am trying to add up only positive numbers.
SAMPLE:
if (num>=0) {
sum= sum + num;
}
else
how would the else in this case being a negative number not be included in the sum

How can I extract the number out of the string:
string my_sting = "item code = 9";
I want to get the '9' out of the string and store it in a separate int variable. I tried using sstream library and was having trouble.

I am practicing with C++ since I done most of C already and I have a problem with reading spaces from a .txt file.
I created a little program that creates a wannabe Cube in wannabe 3D xd, well to appear as 3D like:
Code:
cout << " O------O" << endl;
cout << " / /|" << endl;
cout << " / / |" << endl;
cout << " / / |" << endl;
[Code] .....
The actual code is a bit longer since it offers you to input the size and then it draws the pic. Now that wasn't so hard and I've done that but now I wanted to implement the "MessageBox" func for output.
I managed to write the cube in file cube.txt but when I'm reading from it 1 char at a time since I need to output as char array it avoids all spaces and new lines and just puts all symbols in the same row.
I didn't have that issue with C and I've found on stackoverlow a solution using strings & getline but I need it to be in "char" form.
How to actually read spaces and newlines? This is my current code for reading from file:
Code:
ifstream di("kocka.txt", ios_base::in);
char c[5000];
int br=0;
while( di >> c[br])
{
br++;
}
MessageBox(NULL, c, "Kocka", MB_ICONHAND);
di.close(); P.S kocka = cube (in croatian )

Basically, the task is to replace tabs with spaces, ensuring that the number of spaces is appropriate to get you to the next tab stop (i.e. if you were only 4 spaces away from a tab stop, don't replace the tab with 8 spaces).i've seen have included character arrays, and many have included multiple functions. I realize the text says "these exercises suggest programs of somewhat greater complexity than the ones earlie in this chapter," but it seemed like a very straightfortward task.Have i oversimplified or something?
Code:
#include <stdio.h>
#define TAB_STOP 8
int main()
{
int c, i;
}
