I am at a loss with an assignment. I am supposed to read from a text file, with an input of something like this: alphaproleone,stroke,42 1 and Store it into an array of structures and then output it with each word/number starting on a new line. My current code prints out only the first part, and the "a" in alphaproleone is the actual number "21".
#include <iostream>
#include <string>
#include<fstream>
#include<iomanip>
using namespace std;
typedef struct drugtype {
string name, target;
int effectiveness, toxicity;
The first line of my input file is going to contain some number "T" which will represent the "combination length" of a list of random words. (In this case, they are Taco Bell items). The first number on the second line represents the number of unique items on the menu to get, and the second number on the second line represents the number of unique items that are supposed to be bought.
Basically the input will look like this: 2 3 2 taco burrito nacho
And the output looks like this: burritos nachos nacho taco burrito taco
This is what I have so far:
Code:
#include <stdio.h> #include <stdlib.h> #include <strings.h> int main(void){ int N, T, K; char menu[N][20];
[Code] .....
What I am trying to get working right now is just to scan a file and put the strings into an array so then I can work on sorting the array. How can I add strings from a file into an array?
I am trying to put pieces of a csv file into an array, but i only want to put certain pieces of it. This is the information that i have
Player,Current Team, Age , Nat , Position ,From,To,Transfer fee Gareth Bale, Real Madrid,24,Wales,RW,Tottenham,Real Madrid CF,91000000 Edinson Cavani,PSG,26,Uruguay,CF,SSC Napoli,PSG,64500000 Falcao, Monaco,27,Columbia,CF,Atlético Madrid,Monaco,60000000 Neymar, FC Barcelona,21,Brasil,LW,Santos,FC Barcelona,57100000 Mesut Özil, Arsenal,24,Germany,AM,Real Madrid ,Arsenal,50000000 James Rodríguez,Monaco, 21,Columbia,RW,FC Porto,Monaco,45000000
With this i want to skip the name and team but need age.
I'm trying to pass several integers into the array idAr[10] from an input file using a for loop and then having them output on the console. The output should look like this:
#include <iostream> #include <fstream> using namespace std;
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:
Osgood,Marcus 298542123 CHM FR mosgood@whatever.edu Cronk,Melissa 873489021 BIO SR mcronk@whatever.edu Pry,Seth 349908431 MTH SO spry@whatever.edu Langlais,Susan 783323545 ME SR slanglais@whatever.edu Davis,Nicole 987543345 PHY FR ndavis@whatever.edu
It's supposed to split it up into name, ID number, major, year, and email. The file reads it without any errors, and assigns name to the first part of the structure. However, ID gets assigned the ID, major, year, and email. Then Major gets assigned major, year, and email. Year gets assigned year and email, while email just gets assigned email. I don't know if it has something to do with the loop. For example, this is what I get what I print just the name and the ID.
Cronk,Melissa 873489021BIOSRmcronk@whatever.edu
Pry,Seth 349908431MTHSOspry@whatever.edu
Langlais,Susan 783323545ME
Davis,Nicole 987543345 PHYFRndavis@whatever.edu
Anyway. This is my function code for reading the array. I have it printing the ID number just to see if I can catch the errors earlier:
I am trying to read from a data file that has input as :
12.0, 11, 123 14.0, 12.1, 3
And I want the program to read the data from the file and then make it into an array of structures and then print that array afterwards.
Code: #include <stdio.h> #include <stdlib.h> #define MAX_INPUT 1000 int n =0; int i = 0; typedef struct { double x[MAX_INPUT];
[Code] .....
The program when run gives the following output:
Ishtiaque-Mohammed-Khans-MacBook-Pro:Comp20005 IshtiaqueMKhan$ gcc -Wall -ansi -o ProjectB ProjectB.c ProjectB.c: In function "main": ProjectB.c:59: error: incompatible type for argument 1 of "print_array"
So I have a double array, where I'm inputting float numbers to certain points in an array. Sometimes, the numbers that are printed out are completely different from what I put in.Here is the part of the code:
Code: .
while( token != NULL ) { num = atof(token); test[j][i] = num; printf( " %s, i is %d, j is %d ", token,i,j ); printf( "number is %f value test of i,j is %f
[code]....
Why the float num prints out fine, but when put into an array becomes garbage?I'm taking string values from a csv file and turning them into floats, but no problems seem to crop up there.I reset i when appropriate and increment j when needed, so I don't think my problems are from incorrect array values (though they might be)
I have a program that stores health information the user inputs, one person at a time. The program works perfectly with the exception of storing the data...I need to open a file and read what health data it has in it already, if any, but store the new changes, and appended data to the array of structures, to the data in memory. All of the information is only saved back in the file once the program terminates. I'm not sure how to go about doing this, so I am also not sure what to put in the function for "Save and Exit" that the user can choose in order to exit the program.
I am having trouble putting data from a txt file onto a vector of a class. For instance.
class employee{ setname(string) { some code } getname () { some code } setid(int)
[Code] ....
How would use my setname function in my class using my vector? I tried doing vec[num].setname(tempname) but it doesn't work. I know it does not work because I have to use .push back for a vector but I don't know exactly how to pushback using the set name function call.
I am trying to use a combination of windows batch scripts as well a C++ program to put users data into one single .CSV file. Right now, I have a batch file that will output data from the command line into multiple .txt files. These files are mac.txt, serialnumber.txt, computermodel.txt, and computer name.txt. What I want to do, is to have users run the batch file, which will in turn run the .exe C++ file which will concatenate all their data into one file, computerinfo.csv. The file format for this file would be to have the mac address, serialnumber, computer model, and computer name all in their own column.
My main issue is that these individual files don't have the format that I would like, but based on the command prompt functions, there isn't really any good format. For example, the mac.txt file has the following format:
Physical Address Transport Name =================== ========================================================== xx-xx-xx-xx-xx-xx DeviceTcpip_{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} yy-yy-yy-yy-yy-yy Media disconnected zz-zz-zz-zz-zz-zz Media disconnected
but all I really want is xx-xx-xx-xx-xx-xx
The other files have other issues with format, but if I can figure out this one then the others should be a piece of cake.
Also, I want the output of this to all go in one row, and as other users run this file, they will go into new rows without touching the rows above.
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 was given an assignment on outputting the number of upper and lower case vowels from a text file. I was provided guidelines, but I'm still very new to arrays. how:
1. The values would be sorted into the array 2. To correctly output the array. 3. What information seems to be missing.
bak kut teh[tab]888.0[tab]989.0 spicy chicken nugget[tab]999.0[tab]978.0
I'm experiencing some problem in trying to scan and put it into an array for the food names (e.g an array for food which consist of bak kut teh and spicy chicken nugget) and another 2 array for the other individual integer into C. However there seem to be some problem with my code.
Is there a difference if I use both tab and space instead of space for all?
I have this program for class where we just need to show that we can read, write to a text and binary file. We also need to populate an array from both a text and binary file. When the user first runs the program, the user is told that text/binary file does not work for reading because they do not exist. The user is then asked to start inpuyting integers into the console and at the same time creating and appending to a text/binary file. These values are also stored into an array as they are being inputted. Later in the program the array is run through a for loop and displayed to the screen. Displaying the array to the screen works fine here.
My problem is when the user runs the program for a second time. The text file is opened and an fgets is run to populate an array based on the numbers in the text file. That array is then used again for the user input and file writing section of the program. When the array is displayed at the end of the program the numbers do not make sense. Some appear to be correct bu most do not. When I do the similar actions to the binary file there is no problems. The text file is amended properly everytime the user runs the program. userInputText[MAXSIZE]is a char array (MAXSIZE is defined at 100000) and both textCount and textCounter are initialized to zero when the program is at this point.
Here is what the code where I believe the program resides. I have also attached the source file.
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.
How do I store pointers to a struct in an array ? I am using sprintf to concatenate some values together and then output it to an array in its 1st argument. A portion of my code is shown below.
I am going to be using a boolean variable to mark whether or not a specific field has had data entered into it. I figure the best way to do that is to initialize all the elements of the structures to 0. However, with strings and with the nested structure, I'm not sure how to do this.
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].
So I am working on a FUSE filesystem and I currently have the need to load the contents of a text file into an array.
My array initialization looks like: char array[max_entries][PATH_MAX] = {NULL}
The reason I want to pass it by reference is that I want my function to return two values essentially. One a specific char* and the other an array like I initialized. My function proto type looks like:
char* load_meta(char* list[max_entries][PATH_MAX], char* path, int mode);
How I'm trying to call the function:
someChar = load_meta(&array, path_name, 1);
Within the function I try to edit the array by deferenceing it once, like this:
