C :: Read Text From A File Into Arrays To Set Categories
May 15, 2013
I'm making a Jeopardy game and when I read text from a file into arrays to set the categories, questions and answers a couple of the strings are not terminating and they are printing that junk box thing at the end.
When I use the debugger and print the problem strings they are showing up as "Thanksgiving21" or "Calvin Klein21" but all the other strings aren't having that problem.
Then for example I will change "line[strlen(line)-1] = '';" to "line[strlen(line)] = '';" and other strings will have that problem but not those stated ones. I'm using line[strlen(line) - 1] = '' to get rid of the newline fgets appends on the end of the strings.
how I can read information from a text file into an array so afterwards I can display the array and it will show the contents of the text file?
the information inside my text files consist of names and numbers like so: "Collins,Bills 80" should I separate the numbers and names into two separate text files one for names and one for numbers?
I am having a trivial trouble on how to create three different arrays from a text file. I am a beginner in C++. I have a .txt file containing a string of 'float' values as below:
0.5 0.6 0.7 0.8 0.9 1.0 1.1 1.2 1.3
//----------------------
Now, I want to make three arrays, p1[], p2[], and p3[] from them, so that p1[] has elements from line: 1, 4, 7, ..., p2[] has elements from line: 2, 5, 8, .., and p3[] has elements from line: 3, 6, 9,... of the .txt file.
My original file has a huge amount of data, so I would have to use a loop, but I cannot think of a way to fill my arrays as described.
I have to read 2 arrays, put them in a file. Then make a 2nd program, read the data from the file and show the 2 arrays. I believe I have fully completed the first program, but I am still working on the 2nd one. On the 2nd one I am trying to create a function that displays the data from the file.
//first part #include <iostream> #include <fstream> #include <string> using namespace std; const int num_stores = 3; const int col = 4; const int size=4; void showData( const string[], const int[][col], int size );
Read the input file of data ( employees.txt) and store them in arrays. This company can have up to 55 employees [b]i need to do these following in these program:
Write a function to read the input file and store the data in arrays. Write a function to calculate regular pay. Write a function to calculate overtime pay Write a function to calculate gross pay. Write a function to bubble sort the employees into order by last name, first name. Write any swap functions that are needed. Write a function to write output to a file called payroll.txt
Format of file is EMPLOYEES.TXT[/b]
Hours Pay Rate Employee Number First Name Last name 40.0 10.00 A1234 Jane Adams 50.0 10.00 L8765 Mary Lincoln 25.5 10.85 W7654 Martha Washington 52.0 15.75 A9876 John Adams 45.0 25.00 W1235 George Washington 40.25 55.00 L9087 Abraham Lincoln 30.0 9.75 T9876 William Tell 42.5 12.50 M7654 Missy Muffett 30.0 10.00 P8765 Peter Piper
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.
There are 7 candidates and 365 votes in total. I need to do this using an array of structures. I need to read from a text file each of the names of the candidate and the number of votes they get. At the end i need to output the winner of the election.
Each candidate gets +1 vote for their number electionCandidate[0] for each one he gets one vote and so on for the rest. 365 voters in total.
I was able to input the name for each Candidate from the text file. Now the problem is putting each vote to the corresponding candidate. Also any vote that is above 7 is a spoilt vote which i am trying to count in the above code. The code compiles but it crashes.
I am using while(!feof) but it seems that its not working or this is not the correct way.
A company uses two text files: one to store employees' details and another to log their sign in/out time.
The details file - called details.txt" has the following format: ID, Name, Date of Birth, SSN, Department, Position - separated by spaces.
An extract from the file looks like this:
10 alice 4/23/1972 123-45-6789 support assistant 3 bob 6/7/1980 111-12-1134 logistics manager 1 carol 10/2/1963 987-123-1143 admin ceo 2 dave 10/3/1974 902-22-8914 admin cfo 17 erin 6/13/1991 126-83-1942 technology supervisor 15 frank 2/22/1987 303-12-1122 logistics assistant
"timelog.txt" contains daily logs of when employees arrive and leave. It has the following format: ID, Date, Arrival Time, Departure Time - separated by spaces. An extract from the file looks like this:
I have to write a program that searches for specific records using some search parameter, and displays them. Ok first i have to read the data from the files and store them. this is what i have so far....
#include <iostream> //Accesses libaries for console input and output #include <fstream> //Needed to access the fstream object to read files #include <string> //Needed to access the string class #include <cstdlib>
[Code] ....
I know my class and array code is totally wrong i dont know how to store the data for the info is in integer and string form... do i use strings, arrays?
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 creating a program to read information about class schedules at my school, reformat the information, and allow the user to search for specific semesters. There are eight fields of information. I'm reading the info from a text file using eight parallel arrays, but I'm having trouble declaring the arrays. I can run this code in one compiler (Dev-C++) with no problems, but I get errors when trying to compile it using Visual Studio stating that arrays must be declared with a constant value. I have a loop to run through the text file, with a counter to increment with each subsequent line, then I create a constant int equal to the counter, and declare the arrays of size equal to the constant int. Here's the section of code in question:
// Counting the number of lines in the text file inFileForLines.open("CIS225HW1DA.txt"); string countLine; int numberOfLines = 0; //Discarding the first line of the text file containing only column headings getline(inFileForLines, countLine);
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.)
I have three tables (company,department and employee). Company table has two rows (CompanyID, CompanyName). Department table has four rows (DeptID, DeptName, CompanyID, EmpID). Employee table has three rows (EmpID, EmpName, EmpAddress).
I want to search by Departments For example I want to have one Checkbox named Department if I checked Department it should show me all the available departments in the Company so if i select a particular department it should show me all the employees that they belong to the department that has been selected.
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.
