Reading in a maze into a 2D array. The first two reads will give me the dimension of the maze(ex. m x n maze). So in order to create the 2D array i need the first two reads. Then after it is created it will read the rest of the data which are 1s and 0s. I have to create a program that will solve the maze but i cant test my movement code if i cant read in the data first. the entire program compiles but to test if i read the file i have a function to print it. But it says "There are: 0 rows and 0 columns " so it didn't read anything since rCount and cCount are initialized to 0. and basically the maze has nothing in it.
I have to take a text file with 62 8 25 7 90 82 22 46 15 54 in it. The array has to read from the file. I cannot figure out how to do it. This is what I have.
I know to read a strings into array and tables.. what is they are mixed up?? strings are just names ( 3 characters) and there are bunch of table.. the max size was set to 60
ex. text file
JES DAN JEN . . . 01010101 10010101 RAM JET 01010010 10100101 .... and so on
I have a project which is about linked lists in the order of: a Story is made of Paragraphs which is made of Sentences which is made of Words. We must treat Words specifically as character arrays, not strings. So I need to read in a story from a text file and make Words by finding the first whitespace/punctuation(everything before the whitespace up until the whitespace or punctuation is the Word), all the Words up to the punctuation are a Sentence (Sentence is a linked list of Words), Paragraph is all the Sentences up until an empty line, and a Story is all the Paragraphs. So I know doing this will let me take a line and put it into a character array:
char charArray[25]; //we are allowed to assume a word won't be longer than 25 characters int i = 0; ifstream myFile(fileName.c_str()); if(myFile.is_open()){
[Code].....
I suppose I could look at charArray[i] and if it is ws or punctuation then make the Word = charArray[i-1], but is there an if statement I could do that would prevent the ws or punctuation from being read into charArray in the first place? Because a problem I see with the charArray[i-1] method already is that "This is a story." would get put into the array as Thisisastory. and thus I'd be unable to break up at a space.
So to summarize: I want to read in a text file character by character into a char array, which I can set to length 25 due to context of the project. I want to read in each character and at a whitespace or punctuation, I want to take everything already in charArray and feed that into a Word object constructor (the next Word gets linked to the previous Word, and at a punctuation all the Words linked together become one Sentence, and all the Sentences linked before an empty line become a Paragraph, etc). So how can I get charArray to be only characters in a word, then after the word being read-in ends, charArray resets to empty, and then is populated by the next word and so on.
I am trying to read in player names (ex: first last) from a text file into the people[].name data struct. I can successfully read in my card file, but I cannot get this to work. I get a seg fault. I believe this is because nothing is actually being read in for my while loops. I can't use std::strings so these must be c-style strings aka char arrays.
// deck of cards // below are initializations #include <iostream> #include <fstream> #include <ctime> #include <stdlib.h> #include <string>
using namespace std; //globals const int maxCards = 52;
extracting records from a text file based on the user input of a specific date. Below is a image of the Text file with Dates and records that follow. a code to extract records from file based on the day the user enters with month and year not necessary here.so it is based on the day the user enters, which the code will extract the records and if day is not found then "DATE NOT FOUND"
I'm writing a code which has to read a text from a file. In this text, there are some symbol and numbers (ex, This is $19 of....). Those symbols and numbers should be replaced with the words from the other file. i.e.
transformed file
This is just an $19 of what the $5 should obtain.
And $19 should be replaced from association file
19 example 5 program
The result:
This is just example of what the program should obtain. I'd like to save the first file content into an array of strings and the same for the text of second file.
I got an assignment to do...and in that i need to get the inputs from a .txt file....and im not getting how to read the data i want and skip the rest thrash.
The program runs fine but i just want it to read the inputs from a text file rather than user manually entering it! what changes should i make in the codes..
I would like to program a simple finite element solver in c++ (I'm a relatively new programmer by the way). This is the issue, I have a text file with all the information of the model arranged in matrices; an input file would look something like this:
I am trying to read lines from a .txt file like this:
// "file.txt" This is the first line. This is the second line.
To do this, I tried using the following code:
int main() { std::ifstream data; data.open("file.txt");
[Code] ....
The output I want is:
This is the first line. This is the second line.
However, all I am getting is:
This is the first line.
I can't quite see why this isn't working. I am decently familiar with file streams in C++, so I thought I would know what I was doing, but apparently not.
I need to open a text file game_scores.txt and i can not figure out a way to.
#include <iostream> #include <string> #include <fstream> using namespace std; int main() {
[Code] ....
the code is used to read the text and take the first 4 pieces of info but i do not know how to do it. i have already created the text file and moved it into the source. i am using visual studios 2012. In 2010 the text file would show a relative path, it doesn't in 2012
read some information from a text file. The program I'm working on is like a simple betting program.
What I need to read are:
match_code - team1 - team2 - odd1 - odd0 - odd2 139 Atletico Madrid - Real Madrid 2.853.40 2.35
But the spaces between datas are not known. We only know that both team names may contain more than one word and there is one space, exactly one dash and one more space (" – ") between team names.
Also match_code is an int and odds are double values.
I am working on my final project for my intro to c++. Its a simple program where you buy a car, choose parts for it, see the price of it in total, buying option, and to view past records.
So my problem lies with displaying the records. For some reason(doesn't many how many records there are) the very last record displays again without the "Model" part, but displays the rest of them fine. In other words, there are 2 problems, the last record is displayed twice, 2nd that added record displayed is missing the "model"(this problem doesn't matter really if you can solve the first problem, but would still like to know why it does that).
I tried debugging it and I believe the problem lies with the --------while(fName.good()). It just decides to repeat it again even though in the text file, it does not have that extra record.
I am trying to read numbers stored in a txt file to populate an integer array. The problem is that the numbers read from a file have to be treated as strings and then I am not able to put them in an integer array.
I tried the stoi function to convert the string in 'box' into an integer but I am getting an error.
Code: #include <iostream> #include <stdlib.h> #include <fstream> #include <string> using namespace std; int main() { int amount=10; int k[amount];
I wanted to improve the game from my last thread. I want to read and store a question in this format: Code: Who invented the BALLPOINT PEN?
A - Biro Brothers B - Waterman Brothers C - Bicc Brothers D - Write Bothers
But when I use fgets() to read the string, it reads all the ' ' literally instead of outputting a real newline. Like if it read the above question, I want it to print something like this:
Code: Who invented the BALLPOINT PEN?
A - Biro Brothers B - Waterman Brothers C - Bicc Brothers D - Write Bothers
I am trying to read in a text file and add strings from it word by word into a Linked List. I'm fairly new at C and don't quite understand pointers. I've had a few different errors just messing around with it, but now I'm getting an infinite loop within my main program.
When I run my full code, it prints 12345ooooooooooooooooooooooo...etc. In my test file the first word is "Hello" so that's where the infinite 'o's come from. If the outer loop is the one that is infinite, then wouldn't the second while loop also execute more than once? What I mean is, why is the second print statement the only one that repeats itself?
