The question I am given is this:
Given a line of words (total character number is less than 100,
start from odd position 1,
and end with newline char "
").
Write a program to reformat it that new output is formed by each char from its odd position first, then its even position char.
I was browsing the web looking for simple yet fun programming challenges and crossed this one. I figured out how to reverse the string in place but I want it to read "blue is house the". I approached it in two ways for the heck of it. My idea was the second one, the first one I googled. I didn't know a simple rbegin() could do that, pretty neat.
I found the question here.[URL] ....
Code:
#include <iostream>
#include <string>
int main(int argc, const char * argv[])
{
std::string phrase = "The house is blue.";

Write a well-commented C++ program that reformats and outputs the date. Prompt the user to input the date in the format dd/mm/yyyy and outputs it in this format month, dd, yyyy. For example, 07/06/2012 is displayed as June 07, 2012. You are provided with the file months.txt containing the months and their corresponding numbers, for example 01January 02February etc. Use getline(monthsFile,monthString) to read in a string from the file, and use the monthString.find() function to search for the number and extract the corresponding month.
-confused by the way she told me to use getline(monthsFile,monthString) => if I just do it like this I only get the first line from the txt file (01January)
-if I try putting all the months on one line in the txt file (which i'm not even sure i'm allowed to do), I'm not sure what to do for the length of my substring output. if I make it long enough to fit longer months like September, someone entering may gets both may and june in the output
-if I input all the months into separate variables, I'm not sure how to make it only output the month entered by the user
the months.txt file is as follows:
01January
02February
03March
04April
05May
06June
07July
08August
09September
10October

In my little experiment i am trying to get the compiler to recognize 1 word with 2 parts from a list of names.
For example: if the user wanted to choose "candy bar", from a list of items which include: "candy bar", "cat", "dog"
My current code can recognize words without a space like cat and dog. But how can i recognize candy bar?
I tried using getline but its of no use.
This is my program, for now it is intended to compute permutations of any string entered, but the function ox will not return the final x value. ox is the function that actually computes the permutations so the return of the x value is critical.
Code:
#include<stdio.h>
#include<string.h>
int ox(int x);
int main() {
int x;
char input[10];

I'm attempting to write a program that will respond to me a lot like cleverbot or Siri. I can take care of making the program do the things I want it to do such as shutdown the computer, play a song, or whatever but I do not yet understand how to make it read strings I say, and make sense of them using certain words in that sentence. I could probably make an endless if statement to see if a string entered (using cin on a string[]) matches a certain other string, covering a million different sentences with a million different combos of words and spelling and capitalization but I want to enter a sentence and have the program search for keywords and then act on them. For example, with "shutdown" and "computer" being the keywords that make the program run the shutdown operation, so that whether I say "Yo, program, shutdown this computer for me!" or "Shutdown this computer", it will use the common terms here, "shutdown" and "computer" to know what to do.

For my code, it will just end when the user inputs a lower number than the previous. i.e.- 10 20 15 "The highest number is 20" when it should be "10 20 5 40 15 -1" "The highest number is 40". No arrays or do/while loops either.

When I drag a control onto the Xamarin studio layout the control just slides back into the toolbox again. The only way to add controls is to edit the .axml file which is not at all ideal.
I have tried re-installing all the components again multiple times and even tried out using a different computer, still no luck. How to use the mono framework on the Visual studio IDE and build the apk using Xamarin studios?

I have created this code; it is a taxi management system. I've made a class 'List' which handle a linked list structure of the waiting taxis and waiting passengers. The class has a public int variable: waiting, which keeps track of the number of waiting taxis/passengers.
#include<iostream>
using namespace std;
class Queue{ //Class for indivdual taxis and passengers, which will be members of linked list.
public:
string id;
Queue *next;
Queue (){
[Code] .....
But when I run the code and type in a new taxi number, the code does not increment the number of taxis by one the linked list by one. I can't seem to find the problem.
BTW, in the 'int main', I've added "<< taxi_list.waiting" at the end of the line after the user inputs the new taxi registration number, so that I can see how many taxis are now on the list. This is what is being shown as zero, no matter what.
I have to place two asterisk triangles on top of each other BUT only using 3 for statements. I have gotten the first one:

cout << endl;

I need the output to look like this:

The only kicker is I can have a total of 3 nested for loop statements.
I have a text file that ifstream opens and fills some fields with the data. I've been able to get at the file, by using the precise path, but that path would be incorrect on other computers I'll be working on the project at. So, is there default location I should drop the folder in, and route to with the path? If not which Directory listing in Visual Studio 2013 should I use so the project can find the folder?
This is how I've formatted the string for ifstream.

The best I could come up with is this.
while(true){
wisdomCnt++;
_stprintf_s(szBuffer, _T("%i"), wisdomCnt/10000);
TextOut(hdc,120,10,szBuffer, _tcslen(space));
}
but the program is constantly loading and clicking anywhere causes it to stop responding. Is there a better way to do this especially in Win32 API?
I am trying to place a counter to count in each time a new order comes in, but I am having trouble with the memory allocation part.
I allocate memory to take in names each time an order comes through, but when I print out the names, I get 0x100103ae0....
Assume you want to read from a file and place the data from the file into an array. The array can hold 10 integers. The file may contain any number of integers with 1 integer per line. Fill in the missing loop test condition so that we will read from the file until either end of file occurs or the array is full. Note we are using cin to read from the file since input redirection is being used.
cin >> temp;
arrayIndex = 0;
while ( _____________________________________) {
array[arrayIndex] = temp;
arrayIndex++;
cin >> temp;
}
I am having problems figuring out how to place a list of strings from a text file into a multidimensional array that is something like words[NUM_WORDS][MAX_LEN]. I already run through the file once and count the number of words in it. I have tried a number of loops using fscanf and fgets, but I'm not sure if I am using them right -- this is my first time using them. The text file is a list of words in a dictionary, so the wordCount is about 45340.
Here is my code:
#include <stdio.h>
#include <string.h>
#define MAX_LEN 46
int main(){
int wordCount = 0;
FILE *inputFile, *outputFile;
[Code] ....
Like I said, the wordCount portion works. I added the printf statements at the end to see if anything was being saved, but it just prints two new blank lines. New to file reading and writing.
I have used the following code to attempt to place a binary array into and then retrieve from the Registry. I am a member of the local Administrator group. I have verified that the Registry for the app has a binary array 32 bytes in length under the key "settings" / "keyb" ab 12 cd ...
Code:
// in header
unsigned char m_key[32];
int m_nKeySize;
// in implementation
// int ctor
AfxGetApp()->GetProfileBinary(_T("settings"), _T("keyb"), (LPBYTE*)&m_key, (UINT*)&m_nKeySize);
// in OnDestroy
AfxGetApp()->WriteProfileBinary(_T("settings"), _T("keyb"), (LPBYTE)&m_key, m_nKeySize );
Here is a copy of the binary array in the Registry:
7D DE 2B 30 E7 06 12 AC 99 60 8C 26 21 FC 8E 5B 66 DB 72 9E A2 00 BE 15 E1 8B 67 31 E5 EC 8B 15
Here is the binary key retrieved from the Registry using the code above:
D0 EB 26 00 CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC
