C++ :: Reading Till End Of File And Saving Into Array

Feb 8, 2013

I am using fin.peek() to read character from input file and saving each character into an array. Each line from the input has first name, last name, id number, and then 5-6 grades. Random spacing between each one.

input file example:
Adam Zeller 45678 80 87 60 90 88 100
David Young 34521 34 56 76 76 76 76
Carl Wilson 909034 90 90 90 49 39

my code for reading in and storing each character is this:

while(fin.peek() == ' ')
fin.get();
while(fin.peek() != ' ') ///// first name {
c = fin.get();
first[i] = c;

[Code] ....

The problem I am having is what sort of loop would go around this to read till end of file. I have tried eof. I have tried while(!fin.peek == ') and I have tried a couple of other methods. these methods resulted in a never ending loop execution.

C++ :: Saving Array Data Into Text File

Dec 4, 2013

I have a program that saves all information temporarily into memory (into the array), however, I need a permanent save solution. I have the full program working correctly, formatted perfectly, but it's missing the file array to file output.

Essentially, whenever I'm presented with the menu I'll be able to add entries, search by last name, show the entire list, and exit and save. Whenever I select option 4 the program should save to a file "address_book.txt". Whenever I reload the program, it should load from "address_book.txt" and populate the array with the preexisting data.

My question is focused on how and where I should implement the file output. What I have thus far:

#include <iostream>
#include <string.h> //Required to use string compare
#include <fstream> //Eventually used to store array into file
using namespace std;
class AddBook{

C/C++ :: Reading A File Into Array Then Reversing The Array

Jan 19, 2015

This is what I am supposed to be doing with this problem: Read the integer values in the file "numbers.dat" and display

* them in reverse order (that is, display the last number in the
* file first, the second-to-last second and so on). Use an array to
* store the values. It is safe to assume that the file contains no
* more than 100 values.

I have gotten far enough to read the file and display as an array, but it is displaying vertically rather than horizontally. So it is displaying 10 and a 1 on the first line then the 0 on the second line. Before I can work the reverse part out, I need it to display each number as 10 line 1 -235 line 2 so on and so forth.

This is my code so far:

void display_array_reversed() {
ifstream fin ("numbers.dat");
if (!fin){
cerr << "Error opening file" << endl;
exit(1);

C :: Reading From A File And 2D Array?

Apr 25, 2013

So if I have a file that has a list of scores and the name of the student, how am I going to read the scores and names, and print to output? For example, the text file will look like:

83 75 89 90 75 67 John Doe
67 92 78 64 88 95 Jane Waters
76 65 87 70 97 76 Billy Bob

And they'll be printed like that too.

I made a 2D array for the scores and names, and was able to scan the scores into the scoreArray, but I am stuck for the names. Do I use fscanf, fgets, etc? And how do I use these for a char array?

insert Code:
int main {
int scoreArray[NUM_ROW][NUM_COLUMN];
char nameArray[NUM_ROW][SIZE];
...........opened file, etc.

[ for (row=0; row<2; row++)
{ if(row>0)
{printf("

[Code] ....

When I run this, I get the scores and names (somewhat) in a jumbled mess.....

C++ :: Reading In TXT File To 2D Array?

Mar 27, 2013

My assignment is to read in from a .txt file two things: an integer and a string. After reading in these 2 items I have to put them into a 10x10 2D array so that both the number and the character can be manipulated by the user. Here are the contents of the text file:

Dr. J's Garden
0.21,B, 2.80,G, 4.96,B, 2.66,B, 4.48,B, 0.61,T, 0.40,B, 3.50,G, 3.63,B, 3.91,T,
2.33,T, 4.51,G, 1.15,G, 4.95,T, 2.76,T, 4.51,T, 2.54,G, 4.04,T, 2.38,B, 0.62,B,
4.54,G, 3.38,T, 1.57,T, 3.92,T, 3.03,B, 4.72,G, 0.23,B, 4.02,G, 4.69,G, 0.66,G,
1.34,T, 2.21,G, 2.48,G, 4.85,T, 3.25,G, 3.55,G, 4.78,B, 0.81,G, 0.74,G, 2.55,G,
3.35,G, 4.52,G, 4.81,G, 2.67,G, 4.97,B, 0.87,G, 1.28,G, 4.58,B, 1.91,B, 3.69,B,
3.02,T, 3.15,T, 1.08,T, 4.68,G, 1.10,B, 3.17,G, 1.97,T, 0.99,G, 4.50,T, 3.87,T,
3.36,G, 1.60,T, 3.73,G, 2.14,B, 3.68,B, 2.44,G, 3.10,G, 4.54,B, 0.25,B, 0.25,G,
1.79,B, 3.02,G, 2.21,T, 0.22,G, 3.67,B, 4.46,G, 2.14,G, 2.31,G, 0.80,T, 3.83,B,
1.56,B, 1.41,T, 0.80,G, 1.27,T, 0.08,B, 1.20,G, 2.88,B, 2.78,T, 3.30,B, 1.75,B,
2.60,G, 4.72,T, 4.55,T, 0.89,B, 0.52,B, 2.06,T, 0.28,G, 4.36,T, 4.41,G, 0.36,B,

One number and one character need to be assigned to each element of the array. I know exactly how to fill a 2D array when it's just numbers, but the characters and the commas are giving me a lot of trouble.

C :: Reading A File Into Array Of Pointers?

Mar 24, 2013

why when I print out "array[2]" nothing prints? It just prints blank space. My file definitely has text in it, but when I try to assign "text" into the array of pointers it won't show any text. I know fgets() appends a newline at the end of the string, not sure if that has anything to do with it, but I've tried printing everything that should be in "array" with a for loop and I get nothing.

Code:
#include <stdio.h>
#define FILEPATH "/home/user/Desktop/text"
int main(){
FILE *myFile = fopen(FILEPATH, "r");
if(myFile == NULL) return 0;
char text[100];
char *array[100];
int idx = 0;
while(fgets(text, 100, myFile)){
array[idx++] = text;
}
puts(array[2]);
}

C :: Reading File To Array Of Structures

Jun 9, 2013

I have to write a program that reads from a text file, which contains a list of stock hourly prices and the company names. Something like this:

78.52 82.56 75.10 71.97 Water Company
22.40 25.68 21.37 22.96 Mega Shipping Inc

There's suppose to one array of companies, where each company will be kept in a structure that contains: a pointer for the name, an array of the prices, and the average price for the day. The structures will be kept in an array of structures.

My question is, how do I read the data from the file and put the data from each line into the next structure in the array of structures? I read the numbers in fine. I just use:

Code: fscanf(fp, "%f", &companyAry[i].hourlyPrices[j]);

But my program crashes when I try to read the name.

Code: fscanf(fp, "%[^]", &companyAry[i].companyName);

I'm thinking it has something to do with the fact the companyName is a pointer.

My structure looks like this:

Code:

typedef struct {
char *companyName;
float hourlyPrices[NUM_PRICES];
float avgPrice;
}
COMPANY;

C :: Reading Values From CSV File Into Array

Jan 21, 2014

My problem is that I need to take a csv or excel file with tens of thousands of datapoints, write all points in a section of column to an array, perform calculations on them, and then write it back into another column.

I've been looking all over the internet for ways to do this easily. So far I have not found anything that I can follow and implement.Some codes have been slightly useful, but they aren't commented in a way I can understand. How to write code to take, for instance, lines from column b between 500-1000, write them to an array, and write another array 500 characters in column c. If that code could be commented, I have tried a few different techniques (counting commas), but haven't gotten anything to work.

C :: Reading Data Into 2D Array From A File

Apr 29, 2013

I'm having issues reading to a 2d array from a file. When I try to read the data from my file into my matrix variable it simply doesn't read anything and leaves the variable unmodified. I've tried just reading the first piece of data in the main function and it doesn't work there either. I'm really perplexed at this point since I've never had an issue reading from a file before. Here's my relevant code:

Code:
int main(int argc, char** argv) {
double matrix[MINSIZE][MINSIZE]={0}, vectors[MAXSIZE][MINSIZE], ans[MAXSIZE][MINSIZE];
FILE * inFile;
inFile = fopen(FILENAME,"r");
if(inFile==NULL){
printf("File does not exist.

C++ :: Reading Int From Text File With 2D Array

Nov 3, 2014

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.

Code:
#include <iostream>
#include <fstream>
#include <stack>

C# :: Reading A File Into A Byte Array?

Jun 25, 2014

I basically want to create a save editor application that will enable people to alter various values in the save by clicking on releveant buttons and then also for the editor to auto update the checksum when changes are done.

The save file is in hex so from what I can gather I would need to create a button to open the file using 'open file dialogue' and then read the file into a byte array so that the values can be called at any time when a particular butto is pressed and the application will then seek to the point in the file to make the required changes.
