C :: How To Read A Text File Into Array Of Strings
Mar 3, 2013
In a program, I have a text file (called MyDictionary.txt) which has thousands of words in alphabetical order. I need to make a C program that reads in this text file and then makes an array called char Words[# of total words in the text file][length of longest word].
i have prepared a code the read from txt file with values such integers and strings. but the code i have prepared reads only 1 line. how can i make the code to read multiple records from txt file.
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 am suppose to make a program that reads in data from a text file (integers only) and sorts them as it inserts them into an array of size 10. I did this using an insertion sort, which worked great. But now I am being told that I need the function has to read ALL of the numbers in the text file, not just the first 10, and I am not allowed to store them THEN sort, it has to be sorted as being stored.
While I execute the fileprint function i was able to retrieve the record from the txt file. but at the end of the console im getting randoms number i have tried to understand what causing the problem. I have attached a screenshot....
Code:
void fileprint(){ Code: int c; struct student{ long id; char name[20]; int mid1;
Write a program that reads several strings from a file. Display the number of words then display each word as shown in the sample below. Assume that the maximum number of string in the file is 100.
Sample Input (.in): Smitty Werbenjagermanjensen. He was number 1!
Sample Output:
Total Number of Words: 6
Word[0] = Smitty Word[1] = Werbenjagermanjensen. Word[2] = He Word[3] = was Word[4] = number Word[5] = 1!
For an assignment I have to write a program which basically converts 8 bit binary numbers to ASCII and outputs the assembled text. Here's the catch:
The 8-bit binary numbers are provided by some external file (which only contains 8 bit binary numbers); the name and hence length is not known. The external file is called with a pointer upon execution
(./"conversion program" < external_file.in).
I'm getting the 8 bits as a string, calculate/convert decimals, output char type. HOW do I know when to stop the loop? If I just pick an insanely high number I get random stuff at the end; no boundaries obviousely lead to an infinite loop. Can I determine the lenght of this random ext file somehow nonetheless?
Is it possible to create a vector which dynamically adjusts itself until there are no more strings = end of the file?
I have a pre-declared array which sorts strings to it's alphabetic order and want to change it so it reads from stdin.
char *array[] = {"aaa", "ccc", "bbb", "ddd"}
I tried doing something like this:
for (i = 0; i < length; i++) scanf("%s", &array[i]);
I just can't bring it to work. Another thing is, the input is a a bunch of strings separated by commas and ends with a period. Since I have to make a working C model which gets translated to assembly language later on I can't use functions like strtok.
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 need a program that reads the number of lines of a file and then several (max of 20) lines of text from a .txt file so an example of the .txt file is: 2 This is the first string This is string number 2 So it first reads the 2 and then reads the two lines of text. It stores the text in an array of pointers. The code i have so far is:
It doesnt give me any errors but all it does is keep running and doesnt print anything out kind of like its in an infinite loop although i dont see how that could be possible.
The Objective Of This Program Is To Create A File To Write Text And Read Back The File Content. To Do That I Have Made Two Function writeFile() To Write And readFile() To Read.The readFile() function works just fine but writeFile() doesn't.
How writeFile() function Works? when writeFile() function Execute It Takes Characters User Type And When Hit Enter(ASC|| 10) It Ask "More?(Y/N)" That Means What User Want? Want To Go Next Line Or End Input?
If "Y" Than Inputs Are Taken From Next Line Else Input Ends.
But The Problem Is When Program Encounters ch==10 It Shows "More?(Y/N)" And Takes Input In cmd variable.If cmd=='Y' I Mean More From Next Line Than It Should Execute Scanf Again To Take ch I Mean User Input.But Its Not!!! Its Always Showing "More?(Y/N)" Again And Again Like A Loop.
Code: #include <stdio.h> void writeFile(void); void readFile(void); int main(){
I am writing a simple file/text parser to read a config file for some code I am working on. It's dead simple and not particularly smart but it should get the job done. The code reads a config file:
Here is where it gets wierd. You'll notice that there is an unused variable (filepath) in the config struct. This variable is not referenced or used anywhere in the code, ever. Yet if I comment out the declaration of char filepath[1024], the code segfaults partway through the read_config() function.
My best guess is that there is a buffer overflow elsewhere and it just so happens that the memory allocated for filepath happened to be there to catch it up until now, but I can't work out where it might be happening. With the declaration commented out, the read_config() function gets as far as reading the "padding" variable before it crashes. Yet when the declaration is there, then all the variabled are read correctly and everything seems to work.
I have a .txt file which I want to read from and then write a new text file, this time with sorted lines. It is easy to sort one value, but what about sorting entire lines based on one value?
I want to sort the lines based on the FIRST value.
My text file is in the correct folder and the name of my text file is the same as the code. I dont get no errors i dont see why i cant get my text to be read.
my code.
#include "stdafx.h" #include <iostream> #include <string> #include <fstream> using namespace std; void main(); int menu(); double currentBalance(double balance);
I'm a beginner at programming and I'm not sure how to read in information from a text file. What I want to do is take a text file which contains around 20 rows and 3 columns of numbers, and put these into an array which can then be used for performing calculations. How do I do this? Would I need to declare the size of the array beforehand? When accessing my file, do I include the full address?
The relevant part is lines 29-33:
Code: #include <stdio.h> #include <stdlib.h> #include <math.h> /* this is a simpllified code using BEM equations */ main()
how to read and display the content of a text file in my console application using C++. The file contains 25 lines and 3 columns. The first column is "Rank" (numerical values from 1 to 25) the second column is "Name" (25 teams name) and the third column "value" has the amount of point each team is worth. Looking for code for reading and displaying all this information ....
I am making a script to read the latest from a text file. It picks up the line by numbytes in fseek, but the data line may vary and numbytes not be accurate, how can I fix this?
And another problem is that the line has, date, time, value, separated by space, how to read that line and put these 3 information in variable?
#include <stdio.h> #include <conio.h> int main() { FILE *arq; char Line[100]; char *result; int tam, i; // Opens a file for READING TEXT arq = fopen("temp.txt", "rt");
I'm trying to make a program that will read in names and grades from a text file and print them in the console. However whenever I try to use the OpenFile.get function I get an error saying that there is "no instance of overloaded function"
getting this error resolved before I can.
my code so far (I know it's missing a lot, but that's not what I'm worried about right now.)
How can I read text from a webpage asynchronously,from within C++. After you first connect to the internet using usual means, you enter the string
e.g. "[URL] ...." and the C++ program reads the information: "<title>BBC Website</title><body>This is the BBC website...." from the internet.
Here I want to connect to website every 60 minutes and fetch only first 100 lines of the run.txt file as mentioned above. How can I do this using C++ and asynchronous winsock ???
Code: #define WIN_OS #define _DEBUG_PRINT(X) /* X */
I have been given an assignment that has to do with permutations. I am suppose to read a text file that contains the permutation rules and the text to be "permutated", and then output the rules and the new text into an output file.
So far, I've gotten this:
Code: # include <stdio.h> void printArray(FILE* file, char* array, int maxSize) { int i; for (i = 0; i<maxSize; i++) fprintf(file, "%c", *(array + i));
[Code] ....
Here is what the input file looks like:
Code: 0 1 2 3 4 5 6 7 8 9 4 5 6 0 9 7 8 1 2 3
Moderation in temper, is always a virtue; but moderation in principle, is a species of vice.
Here is what the output file is suppose to look like:
Code: 0 1 2 3 4 5 6 7 8 9 4 5 6 0 9 7 8 1 2 3
ratMnioodetem rpein al,ywa isvirsetu a t m;eod buon r inaticipp,lerina s cpeis of icvies - Temho. -ainaPes
The first two lines are the permutation rules. Currently I have figured out how to read the file into an array and then print it back out into a text.
What I want to do is figure out how to read only the first two line of the input file and store that as a permutation rules, and then continue reading the rest of the input file and store that separately as the text to be "permutated". And then eventually figure out how to apply the permutation to the text.
