C++ :: Hangman Definition Game - Extract Word Randomly Form File And User Guess The Word
Jun 25, 2014Basically I have a text file called words. I'm supposed to extract a word randomly form the file and have the user guess the word. If they guess the word correctly in x number of tries they will receive the definition.
I'm having trouble receiving that random word and I'm getting the definitions from the file.
Here's my code:
#include <iostream>
#include <fstream>
#include <string>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
using namespace std;
[Code] ....
This is what is in the words.txt file
apple#the usually round, red or yellow, edible fruit of a small tree
boat#a vessel for transport by water
horse#a solid-hoofed plant-eating domesticated mammal with a flowing mane and tail, used for riding
television#a system for transmitting visual images and sound that are reproduced on screens
soup#a liquid dish, typically made by boiling meat, fish, or vegetables, etc.
bottle#a container, typically made of glass or plastic and with a narrow neck
barber#a person who cuts hair
toast#sliced bread browned on both sides by exposure to radiant heat
radar#a system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects
red#of a color at the end of the spectrum next to orange and opposite violet
C++ :: How To Read A Specific Word From A File
Aug 12, 2014How would one go about doing this? I am very fond with Windows I/O, but not so much with this subject. I am decent with fstream, probably not as skilled at it as I should be, but I assume <fstream> would be a better choice, since it isn't locked to Windows.
Anyway, say I have a .txt file like this:
Bill is a cow.
Bill likes meat.
Bob is a pig.
Bob and Bill are friends.
And I want to count the number of times "Bill" is written. How would I do that?
C/C++ :: Censoring Specific Word Within Array?
Oct 3, 2014What the program does: I am trying to code a program that makes the user enter a phrase, then censor the word "darn" if the user entered it.
The program is working very well; it will censor any "darn" words the user enter, by replacing it with ****.
The problem: I need to enter a phrase just once, before the program prints out the phrase the user had entered, The phrase purpose is to tell: either the phrase was clean, or it had "darn" within it.
I tired:
1-Defining an integer (counter=0;), and adding (counter=counter+1;) in the first while loop, when I am storing char's into my array. Then, adding if statement (if index==counter) for the phrase I need to print before printing the user entry. It should print out the statement only if (counter==index), because counter would still have the count of user entry. -> didn't work, the phrase won't print.
2- Making the previous step within its' own loop. -> It stopped printing the user's phrase.
Tools I can used : If statements, while loops.
Here is my code: (Ignore the phrases within /**/, they are just the statements I want to print)
#include <stdio.h>
int main() {
char phrase[1001]; // Creats 1000 array ( max. number of letter the user could enter is 1000).
int index=1; // Act as counter, which would refer to a character in the array.
char cur; // Identify cur, which will be used to store characters into the array (phrase).
printf ("Please enter a phrase:

C Sharp :: Remove Specific Char In String
Jul 5, 2013int index = -1;
string NewStr = null;
char[] lower = {'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'};
char[] upper = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'};
foreach (char c in str)
[Code]....
The code above loops through a string and for each character checks to see if it is a lower case character, then checks to see if it an upper case. It then removes it if it is. Leaving only the numbers.
However, it reuses the same string the entire time, never updating the string so it always finds the same (first) character.

C/C++ :: Recursive Function To Move Specific Characters To End Of String?
Oct 16, 2014I am attempting to write a recursive function that, given a string, recursively computes a new string where all the lowercase 'x' chars have been moved to the end of the string.
For example,
moveXs("xxre") --> "rexx"
moveXs("xxhixx") --> "hixxxx"
moveXs("xhixhix") --> "hihixxx"
Below is the code I have written thus far, but it seems to be returning only empty strings.
string moveXs(const string& str) {
string strCopy = str;
if (strCopy.length() <= 1) {

Visual C++ :: Allow User To Enter A Value As C String In Certain Form
Oct 14, 2013My program was to allow the user to enter a value as a C string in the form: xxx,xxx,xxx,xxx,xxx.xx, where x can be any digit. Well, so far here is my attempt. I think the question is, would I have to implement a switch statement for the digits, the comma, and the decimal, so that when a user inputs, let say 52,000.00 the switch statements would read the 1st digit, checks for decimals/commas and if not, proceed to read 2nd digit, and repeat?

C++ :: Storing A String In Byte-array Form?
Jun 6, 2012I am trying to use C# with C++, two different applications that work together.
In C# it is easy to get a byte array out of a string, by just using Encoding.Default.GetBytes(of-this-string);
I can pass bytes to my C++ program by just writing in the embedded resources. But this won't allow strings, as far as I know it can only be a byte array. C++ reads the embedded resources a LPBYTE.
So I try to send the string or message in byteform.
However the problem in C++ is that there is no Encoding.Default.GetString(xxx)
Would there be any other ways to send a message/sentence in bytearrayform and request it in C++ back to the original string?

C++ :: Determine Number Of Times Change Each Specific Character In String To Make It Palindrome
Feb 19, 2015I'm trying to determine the number of times I have to change each specific character in a string to make it a palindrome. You can only change a character one at a time from the end.
Example: "abc" -> "abb" -> "aba" should print 2. "aba" will print 0 because it's already a palindrome. "abcd" -> "abcc" -> "abcb" -> "abca" -> "abba" will print 4 because it took 4 changes to make a palindrome.
I'm not too sure how to approach this - I figured out the case where if it's a palindrome (if reversed string is the same) then it'll print out a 0.
int main() {
int number;
cin >> number; //expecting a number for first line user input
for (int i = 0; i < number; i++) {

C++ :: How To Verify If A String Equals A Certain Word
Apr 3, 2013I want to see if the value of a string equals a certain text. But I can't make it. There are two problems :
1) It seems 'tolower' doesn't work with strings. What to use then?
2) When I delete tolower, it works, but I have an output of "You didn't enter 'add'" even when I do enter 'add'. What's the problem? Is it due to the null byte? What to change?

C++ :: How To Turn A String Word Into Letters
Dec 9, 2013I'm having trouble trying to turn a word into letters. I've seen other posts but they deal with a sentence and it only outputs the words only. What I want to know is how do they take a word (Ex: "word") and break it into individual letters, where I want to store them in a vector of string?
If it's not too much trouble, I would prefer without using pointers or "std:: " marks, since I am trying to avoid pointers and I'm using "using namespace std" all the time.
Ex:
In the example "word", it should output into:
"w"
"o"
"r"
"d"
and I will push them back into a vector of string where each vector element contains a letter.
C# :: Capitalize First Letter In Every Word In A String?
Jan 7, 2014I have a difficulty with string methods for some reason. I tried solving a question from my book, which requires me to capitalize the first letter of every word in a string. I kept trying for maybe two hours yesterday, re-reading the string chapter to see if I'm forgetting a certain method or if something similar was discussed in the examples but I didn't find anything. I also googled it, and found a few answers, none of which I understood. They mostly had keywords or methods I wasn't familiar with. Anyway, here's where I am so far.
class Program {
static string UpperCase(string s) {
int place; string b, st1, st2,st3; char letter;
for (int i = 0; i <= s.Length - 1; i++) {
if (i == 0) {
[Code]....
The code compiles without any errors, but when I enter a string it capitalizes correctly for the first two words and then it starts capitalizing letters in the middle of the words.
C++ :: Outputting First Word Of Each Sentence In String
Dec 20, 2014I have been trying to get this to work for a while now - with no success.
Basically I am trying to write a function which the returns the first word of each input sentence in a single string - this is part of a larger cryptography program I am working on.
So for example, if this string was passed into the function:
"This is what I mean. Is it right? A poor puppy abandoned. Secret torturing of dogs are happening. Message: be on the watch."
It should return:
//declared in class "steganalyse"
string cyphertext;
string punctuation = ".?!;:'";
book is_first_word
[Code] .....
But this only returns the first word:
This
Any other way to return the first word of each sentence in a string.
