C/C++ :: How To Read Information From A Text File And Store It Into Arrays
Mar 28, 2014
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?
My code so far is this:
#include <iostream> //for cin and cout
#include <fstream> //for input/output files
#include <conio.h> //for getch

So I have to read from a file, and store the information in separate variables. My problem is that for some of the information I need multiple words, and for others I don't, so I cant simply store 1 word into a variable and store the next in another in so on. To demonstrate what I mean let me give an example.
Dog Cat Blue Bird Snake White Horse
I am able to store "Dog","Cat","Blue","Bird"...etc in variables but I don't know how to make it so I can store "Dog" in one variable, "Cat" in a second variable. and "Blue Bird" in a third variable. "Snake" would be the 4th and "White Horse" would be the fifth. How can I read a file and manipulate the pointer to grab what I need?

Im trying to read and store several students information so that i can have an options menu where i can enter a student number and the program prints all the information stored about that student. The way i have it set up now, doesn't work for this because all info is reinitialized to stud1. Is there another way to store this info other than defining stud1, stud2,.....,stud200?
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <string.h>
struct student_info {
char first[20];
char last[20];

I was trying to make a program in C that could take Personality Information from the user and store it in a text file. Then, when asked, could compare the results to other entries in the so called "data-base" and tell which is the best match. I tried a whole lot but couldn't think of a proper way.
(Stings and File IO are not my strong points)
I am using Code Blocks 10.05 and the standard GCC compiler.

Perhaps my original wording on this was confusing so I will ask a different way.
if I have a text file called
data.txt
and it has the following in it.
12345
67890
12345
67890
how would i read this information into an array called
int data[4][5]
This is in C.

I am trying to use an array to keep track of the numbers of channels created and how many times a particular channel has been copied. At the moment, the program sets a number for a new channel (1-20), but the user enters the channel name. The channel name is stored in 'ChannelName' variable and if the user copies the channel, it becomes ChannelName_Copy. I want to change the '_Copy' into an incremental identifier such as _C1, _C2, etc.. and to do this i would need to keep track of the channel name and the number of times it has been copied, which i planned to do using arrays but i am not quite sure how to approach this.

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.

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.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char *argv[]){
FILE *file = fopen("questions", "r");
char *string[66], line[150];
int idx;

I am trying to parse a text file that contains information and i cant seem to get started. For example, the text file looks like this:
idx=929392, pl= 12, name= someperson
age=19
state=ma
status=n/a
idx=929393, pl= 12, name= someperson2
age=20
state=ma
status=n/a
idx=929394, pl= 12, name= someperson3
age=21
state=ma
status=n/a
I want to parse the name and age into another text file like this format:
someperson 19
someperson 20
someperson 21
possibly include other attributes next to the age like idx?

For my intro to c programming class, our homework requires us to read a data file and emit various bits of information. the data file looks like this
#Domain: the URL
#Alexa: some kind ranking, small numbers are better
#Rank: another sort of ranking, big numbers are better
#Domain Alexa Rank Site Name
#------------ ----- ------- ---------
amazon.com 13 1177136 Amazon.com
google.com 1 4533883 Google
youtube.com 3 3637788 YouTube
[Code] ....
I've started and am able to get the correct number of lines, and the alexa number, but I keep getting some errors and am just unsure where to correct my code. This is what it looks like;
Code:
// Lexi Anderson
//CS 156
#include <stdio.h>
int main() {
[Code] .....
and once compiled, I get errors.

I need to store the last 3 deposit that I have in my deposit. I have few option but i dont which would be easy
1.Store all deposit to the text file (store always in a new line), and display the last three deposit from the text file.
dep 1 - 60
dep 2 - 40
dep 3 - 100 print 100
dep 4 - 50 print 50
dep 5 - 50 print 50
2. I think this option is more difficult, when it reach deposit 4, to get rid deposit 1
So when i make a deposit 4, the deposit 1 get's ride
dep 2 - 50
dep 3 - 100
dep 4 - 70
Right now i can only display one deposit (last one), then i close the program and run again and i make another deposit it overwrites a new deposit.
My code.
To show sure my deposit that has been made.
double depSave () {
int option;
float dep1,dep2,dep3;// Declare your variables
dep1 = dep2 = dep3 = 0; // Set them all to 0
system ("cls");
string path = "deposit.txt"; // Storing your filename in a string
[Code] ....
Where is says "save deposit" in comment that where it saves to the deposit text file, that going to be output to the depSave function.

outputFile.open("%localappdata%virtualstoreProgram Files (x86)AGC est.txt");
and
outputFile.open("%localappdata%virtualstoreProgram Files (x86)AGC est.txt");
Although I can get it to work using:
inputFile.open("C:UsersNewlanceAppDataLocalVirtualStoreProgram Files (x86)AGCsettingsV5.cfg");
But I need it to work on other machines IE: Not Newlance.

Directions: Write a program that uses the structure named MovieData to store the following information about a movie:
Title
Director
Year Released
Running Time
Include a constructor that allows all four of these member data values to be specified at the time MovieData variable is created. The program should create. The MovieData variable and pass each one in turn to a function that displays the information about the movie in a clearly formatted manner. Pass the MovieData Variables to the display by value.
Code:
#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
struct MovieData {
[Code] ....
I sort of hit a wall did it do something wrong because the whole create two MovieData variables is confusing me.

How would i write a functor for this code. The code is written to read data from a file and store in a multimap.
The data has numbered lines. E.g.:
1 This is a string
2 This is a string too
So the aim is to store each word in the line with the number and then to enter a word to search for the line numbers it appears on. I do not know how to go about and write a functor
#include<iostream>
#include<sstream>
#include<fstream>
#include<cstdlib>
#include<map>
using namespace std;
int main() {
multimap<int, string>myMap;

1523 2536.1
1254 1256.2
17846 8956.2 and so on
left one is time and right one is pressure, I need to show the time value as it is but i need to use the pressure value to calculate air speed. I don't know how to use the strings to pick up the list properly. I did the calculation formula for the air speed but i can't pick the pressure value up from the text file. here's what i did:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
