C++ :: Hangman Game - Reading One Line From TXT File
Dec 23, 2013
My question is how can i read one line from a ".txt" file? To be more clear, i'm trying to write a hangman game. Therefore I'm trying to get words from a "wordlist.txt" file i created. I know a little bit about ifstream, ofstream and fstream. So my function i created to get a random line from this txt (not-completed yet since i don't know how to get that randomized line);
void grw() {
int line;
srand (time(NULL));
line = (rand() % 7972) + 1;
ifstream wordlist;
wordlist.open("wordlist.txt");
}
I created a variable called 'line' for the line number and randomized it (there are 7972 words in ".txt" file). So what i want to do now is to get the word on that line.

Ok here I have a program that reads a word from a text file randomly and matches it with the definition. The user has to guess what the word is according to the definition.
I'm having trouble with my for loop, I'm not getting any errors. But I just know something is off.
Here's my code:
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
#include <ctime>
using namespace std;
int main(){
int number;
int count = 0;
int numOfGuess = 0;
[Code] ...
This is words.txt:
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

Basically 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

designing an algorithm forHangman game.
I've got everything I need that is expected of my program except this.
When the user starts the game they will have these letters available to them:
"abcdefghijklmnopqrstuvwxyz"
Now if they were to guess 'a' it should look like this:
"-bcdefghijklmnopqrstuvwxyz"
then if they were to guess 'k':
"-bcdefghij-lmnopqrstuvwxyz"
and so forth.

I'm making a hangman game. All i need to do is after the user guesses the letter correctly it replaces the stars with that letter. I have been trying for the past 2 hours and cant get it. So basically I have to do this. DisplayWord.replace(0, theWord(0)) but I don't know how to put it in.
This is my code:
#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>
[Code].....

i am trying to make a hangman game. The game works fine so far but i cannot seem to keep track of the letters used. I have to prevent the user from using a letter that has already been entered by the user at some point in the game before. But can't seem to work my way around it. I have included the code below
#include<iostream>
#include<cstring>
#include<cstdlib>
#include<ctime>
[Code].....

I am recreating a hangman game. I'm trying to generate a random number to choose which word from my words list to use and I've done it a billion times before just like this. So, here's my code:
#include <iostream>
#include <cstdlib> //standard library.
#include <ctime> //for random.
#include <fstream> //for reading and writing to a file.
#include <string>
using namespace std;
int main() {
int num_words;
string word[num_words];
[Code] .....
I have the text file "words.txt" info below.
5
dog
cat
horse
pig
bird
If I run the program as it is, I get a segmentation fault core dumped error, however, if I take all the stuff that reads in the words from the words.txt file, like so:
#include <iostream> //every program has this.
#include <cstdlib> //standard library.
#include <ctime> //for random.
#include <fstream> //for reading and writing to a file.
#include <string>
[Code] ....
it works correctly and generates a random number.
I'm using Linux Mint.

I am trying to read a file line by line and then do something with the informations, so my method looks like this:
Code:
void open_file(char *link) {
FILE *file = fopen(link, "r");
if (file == NULL) {
fprintf(stderr, "Could not open file.
");
exit(EXIT_FAILURE);
[Code] ....
1) The first complain of valgrind is at the line where I use fgets and its telling me (invalid write of size x), but I have allocated my line to 56000 and the read line is shorter, why is there a write size error then :S?
2) at the line where I realloc where I try to shrink the space he's telling me: Address .... is 0 bytes inside a block of size 56000, But I know i need only this space so why is there a write over space error :S??

So I'm reading a file line by line and storing it backwards into a list. So if the file has has this format...
1
2
3
4
The code should store each line in a list as such...
4, 3, 2 ,1
Instead the code will store the last variable in all nodes. So the final list will look like this...
4, 4, 4, 4
Here is my code...
struct node *head = NULL;
int i;
while(read(in, &i, sizeof(int)) != 0) {
struct node *temp = malloc(sizeof(*temp));
temp->line = &i;
temp->next = head;
head = temp;
}

Im trying to read from a file, line by line, with no specified number of values in the file. Check out my code:
int main() {
string x;
ifstream fin;
int count = 0;
char ch;
fin.open("CWC_Master.txt");
if(!fin)
[Code] .....
Now, this works great! However, its skipping some lines. And I dont know why. For example: Lets say that the input file is:
superman toy
sm2335
19.99
batman toy
bm5532
25.99
aquaman toy
am6786
26.00
Where it should output the above, instead it outputs every other one. Like:
superman toy
19.99
batman toy
25.99
aquaman toy
26.00
How can I fix my code so that it SIMPLY(i say simply because I am still a beginner coder) can read line by line?

I have to read the information about logic gates from a file. The file format is shown below:
Code:
gateOne = NAND(inpA, inpB)
gate2=NAND(1,2)
3 = NAND(23,25,26)
As, it can be seen from the above structure that whitespaces are not same everytime. So, to deal with this situation, i am using boost library to remove all whitespaces from the line which is being read and then try to find the name of gate and its input. My code is given below which is able to correctly find the gate names and its first input...but my code is not able to find the second, third and so on input names.
Code:
//C
#include <stdio.h>
//C++
#include <iostream>
#include <sstream>
#include <fstream>
#include <string>
#include <cstring>
#include <boost/algorithm/string/erase.hpp>

First of all I need to know how to read from file.
Second, I need to read line by line from the file.
For example, the file contains:
8H 3S TH 9D 5S
5D KD 9H 4D 3D
8C TD 5D QS 2C
I wanna use array, so I need to store 8H in array[0], 3S in array[1], until 5S get stored in array[4].
I need to read the first line, the the second, and then the third.

how to read the next line in the file. I think I need to use a for loop, but not sure how to implement it.Lets say my input.txt file has three names:
Sally
Tom
Sugar
I can get Sally, but not tom as yet. fgets also gets me to the same place.
Code:
int main(){
char str_1;
FILE * ifp = fopen("input.txt", "r");
fscanf(ifp, "%s", &str_1);
printf("%s", &str_1);
return 0;
}

My file has these lines.I try to remove extra line in the end, in notepad/gedit, however, after saving it automatically adds up there.
one
two
three
Code:
void help::read_ref(const char* file_name){
std::ifstream file_handle;
file_handle.open(file_name);
std::string line,name;
getline(file_handle,line);
while(!file_handle.eof()){
[code]......
when I print size of map, it comes out to be an extra then what is should be.
std::map<std::String,std::string> ->is my map
on the contrary if I use Code: file_handle >> line; I get correct number of entries in map.
My doubt: getline, automatically finds and in last, it finds a , why it doesn't end the iteration?
I have faced this issue many number of times.
Code: line[0]=='>' I am making this check, then also, I get a null string as key in my map.
I have printed key with their index, using Code: map iterator .

I'm currently working on making a program that is run through a GUI run through the command line. The program basically takes an app file and a boot file and runs it through a bunch of functions and generates a new outfile. Anyway I'm new to C and can't figure out how to code it so I can type the two file paths into the command line and read them into the function. Is it possible to do this within the "if else" statement?
Code:
int main(int argc, char *argv[]){
const char * const SrcFilePath;
const char * const SRecordPath;
const char * const FopIspFilePath;

finding the last line of the code? I have a program with two functions that open and display a joke.txt and punchline.txt file. My joke function (which reads the entire file) works fine. The punchline function, however, does not.
void displayPunch(fstream &file)
{
char ch;
string fileLine;
bool isLine = true;
file.seekg(0L, ios::end);
while(isLine)
{
file.seekg(-1L, ios::cur);
[code]....
The file, punchline.txt, has a bunch of garbage strings with one real string at the end. I need extract and display only the final line of that file.

Here is my code. Let the variables be of type double.
Code:

{
if(!N)//Read first line of file
{
infile >> d;
infile >> N;
infile >> epsilon;

i would like to read the content of a text file data.txt (line by line ) directly from the command line using this command: a.exe < data.txt.
What could be the c++ code to read/get the content of these lines (without using ifstream). The treatment of the lines is not a problem for me but i really don't know how to access the content of the file from the c++ code

I have attached the file that I need to read into a data structure. In the example I am just printing it to the screen. This following code has worked for me before, but now isn't. I have tried in visual studios, and on unix, and neither are running it. I ultimately need it to run on unix.
Example file:
word
book
programming
Here is my function to read in the file.
ifstream file;
string line;
file.open("words.txt");
if(file.is_open()){
while(!file.eof()){
getline(file, line);
cout << line <<endl;
}
}
file.close();

Why this code outputs 7 lines (the last line twice) while the file contains 6 lines?
cout << "read msgfile
";
ifstream msgfile ("script1.msg");
while (msgfile.good()) //if not at end of file, continue reading {
// load vector with deffile
msgfile >> line;
vectormsgfile.push_back (line);
cout << line << "
";
}
msgfile.close();

I'm trying to read a file from the 2nd argument, skipping the first line of the file since it's the name of the columns, and separate each line as a token, by date, subject, startTime, endTime, and location.Here's my code that I got so far:
Code:
void readAppointment(){
if (arg != 2)
exit;
else {
FILE *fp;
fp = fopen( argv[1], "r");
char line[999];
