C :: Splitting String Into Separate Characters Or Array
Feb 18, 2014I have been looking everywhere, but the only place I have seen it done is Objective C. The Question: how do I split a string, input by the user, into an array of characters? No code shown because I know no commands that do this.
--Input by user as in fgets, or scanf().
C++ :: Splitting Linked List Into Two Separate Lists
Feb 14, 2013I've been given a ton of code (5 files worth) that does various things with a linked list. I'm supposed to add a function to split this list into two separate lists by testing whether or not each number is <,=, or > a certain element. I am completely lost and don't understand linked lists at all. I'm also a bit lost on pointers since it's been almost a year since I've looked at programming, but I could probably figure that out if I could just get this linked list thing down.
Here's my SplitLists function so far:
void UnsortedType::SplitLists () {
// Pointers for each new list
NodeType* list1Ptr;
NodeType* list2Ptr;
[Code] ....
In other places in the code, I have GetNextItem, ComparedTo, PutItem, and ResetList that were already given to me.
C++ :: Separate Input Integer Into Its Individual Digits And Print
Apr 18, 2013Write a full C++ program that inputs three-digit integer, separates the integer into its individual digits and prints the digits separated from one another. For example, if the user types 549, the program should print;
5 4 9
C :: Separate Numbers Evenly Into 5 Arrays
Apr 7, 2013I have a set range, say 10 to 100, and I'm trying to separate the numbers evenly into 5 arrays. So there are 90 numbers, how can I assign 10 - 27 to the first array and the next 18 numbers to the next array without creating separate loops for each one?

Apr 23, 2012I'm sure this is pretty simple, but any way to do this. Essentially if I have an array with P collumns and V^P rows, how can I fill in all the combinations, that is, essentially, all possible numbers in base V of P digits.
For example, for P=3 and V=2
000
001
010
011
100
101
110
111
Keep in mind that this is an 2 dimensional array, not an array of ints.
For P=4 and V=3.
0000
0001
0002
0010
0011
0012
....
Having this array generated, the rest of work for what I'm trying to develop is trivial
This is a code I've written that should do the trick, but for some reason it gives this error on compiling:
"main.cpp:65: error: invalid types `double[3][9][double]' for array subscript"
Code:
for(i=0;i<P;i++) {
for(j=0;j<pow(V,i);j++) {
for(k=0;k<V;k++) {
for(l=0;l<pow(V,(P-i-1));l++) {
a[i][(j*V*pow(V,P-i-1) + l + k*pow(V,P-i-1))];
}
}

C :: Reading Three Digits At A Time As One Number In Long String Of Numbers
Nov 29, 2013How can I read a file that contains numbers only, but read it by three digits at a time? I have a long string of numbers and every three digits corresponds to a particular number in itself. i.e. a string of 064045154 would need to be read as '064' '045' and '154'. I need to then subtract one from each of these numbers and the new values I need to convert into their ASCII characters and place these in a new file. This is what I have (focusing on the 'Decrypt' function) but all it does is in the new file place a string of the same character repeated over and over a total number of times equal to the number of integers in the numbers file.
Code:
#include "stdio.h"
#include "stdlib.h"
#include "string.h"
#include "limits.h"
int Encrypt(char * FILENAME)

C++ :: Read Two Positive Integers That Are 20 Or Fewer Digits In Length And Output Sum Of Two Numbers
Apr 30, 2013so basically my project goes like this:
Write a C++ program that reads in two positive integers that are 20 or fewer digits in length and outputs the sum of the two numbers.
Your program will read the digits as values of type char so that the number 1234 is read as four characters '1', '2', '3' and '4'. After they are read into the program, the characters are changed to values of type int. The digits will be read into a partially filled array and you might find it useful to reverse the order of the elements in the array after array is filled with data from the keyboard.
Your program will perform the addition by implementing the usual pencil and paper addition algorithm. The result of the addition is stored in an array of size 20 and the result is written to screen. if the result of the addition is an integer with more than maximum number of digits(that is more than 20 digits) then your program should issue a message saying that it has encountered "integer overflow".
You should be able to change the maximum length of the integers by changing only one globally defined constant. Include the loop that allows the user to continue to do more additions until the user says the program should end. What I have so far is
#include <iostream>
#include <cstdlib>
using namespace std;
void reverseArr(int a[], int liu);
void addLargeInt(int a1[], int liu1, int a2[], int liu2, int sum[], int& liu_sum);
int main() {
cin.get(next);

C++ :: Input Integer Then Output Both Individual Digits Of The Number And Sum Of Digits
Oct 11, 2014 My problem needs to prompt the user to input an integer and then outputs both the individual digits of the number and the sum of the digits. An example would be entering 8030 and it spits out 8 0 3 0 as well as 8+0+3+0=11 and it needs to work with negative numbers.
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
int base;
[Code] ....
Now I don't know if any of this is right a hint my professor gave us is that to get the fourth digit you would do base mod 10 and to get the first digit you do base divided 1000...
Code:
{
int power;
int counter=0;
int value=1;
cout << "Enter the power of 10 you want: ";

C :: Splitting A File Info Multiple Chunks
Apr 19, 2013I have a tab separated file that consists of 10 columns. (classical txt file).the third column is the one interesting to me it consists of some strings like :
Code:
2313 234ffer string1 sd33 ...
2313 234ffer string1 sd33 ...
2313 234ffer string2 sd33 ...
2313 234ffer string1 sd33 ...
2313 234ffer string2 sd33 ...
2313 234ffer string1 sd33 ...
2313 234ffer string3 sd33 ...
according to the value in the third column i wish to split my text file sot that i have files string1.txt string2.txt and string3.txt such that each file contains the whole line. how to do it in c++ with hash tables (maps) and all those fancy tools all ready and waiting for me to use them but in c i am crippled.
Code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include "strmap.h"
[code]...
My idea was to first go through the file, hash all values in tht third column so i get a unique set of elements and then for each distinct string(element) in the third column create a file pointer, then go once more through the file and as I encounter a specific string(element) type, write the whole line into the appropriate file.
C++ :: Linked List Sorting / Splitting And Printing
Oct 3, 2014Write a program that creates a forward linked list of at least 20 elements, where each element holds a random integer between 0 and 99. Print the list.
Write the function "returnMiddleList" to find the middle element of the linked list in one pass. Print the integer value of this element and the position of this element (starting at zero) in relation to the head (where the head = 0, the element pointed to by the head = 1, the element pointed to by the previous one = 2, etc).
Split the list in half at the middle element to create two entirely separate* linked lists of near equal size (+/- 1) and print the two lists. Modify the "returnMiddleList" function to accomplish this, returning the head of the second linked list and setting the link of the element pointing to that head to null. Then print the two sums of the integers stored in the elements of both lists.
Sort the two lists from least to greatest and print them out (printing at this step is optional depending on the sort approach taken). Then combine the two lists while sorting them again from least to greatest and print out the new list. (HINT: you can subdivide the lists further and sort them on a scale of one to two element lists before sorting and combining the first two unsorted lists. What is this sort called?)
I have got #1 and #2 working, but #3 and #4 is where the issue is beginning. When I split my link list into two lists and print the individual lists out, my first link list prints out 9 numbers when it should be printing out 10 (the 10th number somehow disappears?), but when I do the sum of the first list right after that, the number that has disappeared gets added in the sum! I do not know why it is disappearing, and this is one issue. Another issue is in the second list, a random "0" gets added to the list and one of the numbers is lost. My last issue is about #4 as the merge algorithm I have used does not seem to work (I am merging the list together while sorting them, but I am not using a recursion sort because we have not learned that yet).
