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 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.
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 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".

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

I'm trying to pass these numbers into the array using the for loop: 1, 2, 3, 4, 5. I created two files in my project called "inStuff.txt" and "OUTPUTS.txt". I know I have an error at my input in the for loop, which is a bit similar to my problem or something? I'm also on linux using a crossGCC complier(not sure if that makes a difference).

I'm having issues trying to input data from a .txt file into my array program. The whole program takes the name, # of goals and assists, adds them together to get points, and then puts in a given + or - rating. The program works except for the data input.
Also, this is an alphabetical "Unsorted" list, but is there a way to order the list based on point value and be able to display that as well as a separate "Ordered" list?
#include <iostream>
#include <iomanip>
#include <fstream>
#define NUM_PLAY 30
using namespace std;
int buildArrays(int[], int[], int[]);
void printArrays(string[], int[], int[], int[], int);
[Code]...
And this is the .txt file. Order is Players Name, Goals, Assists, Plus/Minus rating. The points are added when points = goals + assists (Should be in the main coding above).

I am trying to write my files to another subfolder . Below is my program.
Code:
cat th6.c
#include <pthread.h>

#define NUMELM 8
[Code] ....
I observe my filename along with directory as text in the new file created in sublfolder. This is output.

[cporgs/apue/threads]: ./a.out test.txt first
test.txt -- first/test.txt

I could not able to get from where this filename and folder is getting added.
I want to input data into text file while not deleting the original data in the file and I use something as
ofstream writefile;
writefile.open("example1.txt");
if (writefile.is_open()) {
for(j=0; j<N; j++) {
[Code] ....
But this will delete the original data.
# include <stdio.h>;
int main (void){
float judges[6];
int degree;
[Code].....
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 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.
so i got this piece of code today having some slight errors with it, how its actually done as i want to know where i have gone wrong here is the code .. Using a for loop to input and output array values

Ben has been administering a MBTI personality test. Now he has all the responses, but the task of scoring and compiling results seems daunting. The personality test* is a series of 70 questions for which the available responses are ‘A’ and ‘B’. Based upon the answers to the 70 questions, a personality profile is determined, categorizing the degree to which the responses place the person on four scales:
Extrovert vs. Introvert (E/I)
Sensation vs. iNtuition (S/N)
Thinking vs. Feeling (T/F)
Judging vs. Perceiving (J/P).
Each of the 70 questions relates to one of the four scales, with an ‘A’ response indicating the first of the corresponding pair (E, S, T, or J) and a ‘B’ indicating the second (I, N, F, or P). For instance, an ‘A’ response on the question: At a party do you:
A. Interact with many, including strangers
B. Interact with a few, known to you indicates an Extrovert rather than an Introvert; just the opposite for a ‘B’.
For this test, each question is designed to influence one of the four scales as follows:
questions 1, 8, 15, 22, 29 … are used to determine E/I,
questions 2, 9, 16, 23, 30 … and 3, 10, 17, 24, 31 … to determine S/N,
questions 4, 11, 18, 25, 32 … and 5, 12, 19, 26, 33 … to determine T/F, and
questions 6, 13, 20, 27, 34 … and 7, 14, 21, 28, 35 … to determine J/P.
Notice these come in sequences of “every 7th” question.
The goal of the test is to determine which end of each of the four scales a person leans, and to thus classify him/her based on those leanings (e.g., as ENFJ, INTJ, etc.). Since Ben would also like an indication of how strongly the test taker fell into each of the four, the program should print the percentage of ‘A’ responses for that scale.
Input for this program should come from a file responses.txt. The first line of the file will contain a single integer, n, indicating the number of test results to follow. Each of the following n lines will contain the first name of the test taker, a single blank, his/her last name, a single blank, then the 70 responses he/she gave on the test. Although the test instructions indicate that the results are most valid when all questions are answered, sometimes respondents leave questions blank. In that case, a dash appears at the corresponding place in the list of responses.
Output for the program should be written to the file types.txt. It should include a well-formatted report listing, for each test taker, his/her name, the percentage of ‘A’ responses in each scale, and the resulting personality type. A tie within a scale should result in a dash (‘-‘) for that part of the personality type.

I have 3 arrays named: abee1 , abee2, myarray.
I have loop that want to call abee1 , abee2 one each time and copy myarray into it . It means that I reach the name of abee1 to abee2 in the loop for doing this. I made the name of each one by using strings ( abee1 , abee2) in the loop. In the last I want to copy the myarray into the abee1/2 using pointer.

I have written a C++ program I have multiple of CSV file used as input, which I open one at a time and close it after extracting data to a output file which is the only file.
I run getline(inFile,line);
outFile << line << endl;
I run this code, and only part of it is goes to the output file I got, also have spacing randomly to specific file and inconsistent
But when I slower the code, like system("Pause") in the loop, I can get extract what I want perfectly....
Is my program running to fast, why getline would be skipping part of what things I want?
I have a working lab project with a loop error. Code posted in second post. Here's the requirements:
*
- program has to be able to handle file failure
- must loop (prefer to use a while loop here), read in the data, calculates values, etc. and then output the results.
*
The input data file includes
1. a 1 or a 0 indicating that there is a set of employee data following
2. the hourly rate of the employee
3. the humber of hours worked
4. the number of dependents
5. a 1 or a 0 indicating whether the employee is full time (1=full time).
Problem: At first I wouldn't loop back... so I moved the curly brace above the return0;
I'm new to programming and i'm trying to do a certain task. I want to use a for loop to read certain data from a txt file and print them to a console. I'm trying to read student names and their grades.
Something like
3 // 3 represents the number of students.

Sarah 70
Maya 88
The data may vary but it's always in this format.
For some reason, my input seems to lag one behind when inserting data. Attached, I have code that I wrote along with the example of the lag. What may be wrong with my code that is causing this to lag?

// Here is my code for displaying the data from the text file into a 2d array and height next to it, but I am not able to diaplay the height from 60 to 76 next to the row of the 2d array, as shown in the table below. This is my program:
Recently the health authorities have listed a new way to calculate the body mass index (BMI) of an individual.
Values of 20 – 24 are classified as normal, 25-29 as overweight, and 30-34 as heavy.
The table below is a portion of a typical BMI table.
BMI:202122232425262728293031323334
Height:
60102108113118123128133138143149154159164169174
61106111116122127132138143148153159164169175180
.

.
MY task is to write a program that does the following things:
1.Produce the table by reading in the data from bmi.txt (on Moodle) into a 2-D array.
2. Display the table neatly on the screen, with row and column headings. The BMI should go from 20 to 34. The height should go from 60 to 76 inches.
3. Prompt the use for their height (in inches) and their weight.
4. Make the program print the closest BMI.
If their weight is lower than the values on the table, use 20 as the BMI.
If their weight is higher than the values on the table, use 34 as the BMI.
5.Loop the program so the user can find more BMI’s.
