C++ :: Output Data From Two Sorted Arrays Into One File?
Apr 7, 2013
I am trying to output data from two sorted arrays into one file(which should also be sorted). The program works for most of the data, but after it reaches a certain record begins outputting garbage. I'm sure part of the problem is that I don't know what to include in my while loop that outputs to the file.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
I need to write a function that will merge the content of two sorted arrays of type double values. The function should not assume that both its input parameter arrays are the same length.
Here is my program so far - I know there is alot of errors and mistakes:
I am writing a class that dynamically allocates an array that holds a user-defined number of test scores (test scores go from 0 to 10 both included). Once all the test scores are entered and validated (values only between 0 and 10, both included), the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates theaverage of all the scores.The main program should display the sorted list of scores and the average of the scores with appropriate headings.
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 need my code to stop outputting all the numbers throughout the steps it is going through i just need it to output the total
this is my input M C C C L I V
and its output is
Your total is 1000 Your total is 1100 Your total is 1200 Your total is 1300 your total is 1350 Your total is 1351
i just need it to output the last number
// write a program to read a string of characters // that represent a Roman numberal and then convert // to Arabic form ( an integer // input from data file
I am having trouble outputting the file "output1.dat" to the screen. here is my code -
#include <fstream> #include <iostream> #include <cstdlib> #include <string> using namespace std; //Outputs a description of what this program does void intro(); void sort_merge(ifstream& in_1, ifstream& in_2, ofstream& out_1 );
I was recently introduced to the fstream header file. I want to know is their a easy way to print an output with append data in a .txt file.
And secondly I am also having an error with my header file. It says error: cannot open source file "fstring" when I hover my mouse over "#Include<fstring>".
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
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.
cheapest item = Oranges most expensive item = Raspberries total cost = 55.44 shopper = Winnie B. The Pooh
When I run my code however, it doesn't get past shampoo and will continue to add shampoo to the total cost infinitely. How can I change the code to produce the proper information?
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 code has no errors. I'm just having problems with getting the grades of the file sorted. grades is not a struct, but is a int inside struct School. Below is what I;m having problems with(this is just the code I started working with,I made a few changes but it didn't work,I have no clue)
void selectionSortG() { Students min; int key; for (int i = 0; i < size; i++){ min = student[i]; key = i; for (int k = i; k < size; k++)
I define "Comwords" as a string, but apparently it takes the members as chars, then I can't set strings in a structure equal to the chars.
I see to also be having unknown problems with the ComMAL array and loading it values into another element of the same structure.
How to correct this? I was thinking of casting char elements as strings, but could find no reference in my library book regarding how to do that (lots on casting int's a doubles...)
Code:
int _tmain(int argc, _TCHAR* argv[]) { int comm = 10; int targ = 5; int death; struct AI_WORDS
I am having a lot of trouble being able to get data from a file and input it into given structs and arrays of structs and then outputting the file. We are given a file that contains 96 lines and looks like this:
Arzin, Neil 2.3 6.0 5.0 6.7 7.8 5.6 8.9 7.6 Babbage, Charles 2.3 5.6 6.5 7.6 8.7 7.8 5.4 4.5
This file continues for 24 different people and then repeats with different scores (the second line). The first number, in this case is 2.3 for both people is a difficulty rating. The next 6 numbers are scores.
We are given this data in order to set up our structs and arrays and my code:
#include <iostream> #include <fstream> #include <iomanip> #include <string> #include <cmath> using namespace std; int main () { ifstream inFile; inFile.open("C://diveData.txt);
struct Member { char *name; char *address; char Interests[][10];//<------problem int numofInterests; Numbers digits;
[Code] ....
Now the Program:
newMember.Interests[numofInterests]; newMember.numofInterests = numofInterests; for(int i = 0; i < numofInterests; i++) { printf("Enter %s's %i interest: ", newMember.name, (i+1));
[Code] ....
it's a array of cstrings, but i can't figure out how keep it from outputting garbage, i'm assuming it's because i didn't end it with a null terminator but when i did, it didn't work.
/* This is what I have so far what i am trying to do is to initialize the arrays at zero and output the board to the screen. Part of the problem is the user has the option of the board size. All this is suppose to do is to output the board to the screen. I am having problems understanding 2D Arrays. */
using namespace std; int main() { const int BOARD_MAX = 10; // Maxinum Board size. const int BOARD_MIN = 3; // Minimum Board size. array = [COL]; array [ROW];
I then realized that the order that the second method gave me will make it very hard for me to calculate the RGBs. Because they will be calculated like wise..

I am a very fresh c programme user, in fscanf data to arrays. Somehow it just doesn't gets recorded, wonder what is wrong with my code? When I printf the array it always ends up with random numbers.
I am trying to scan a list of 3 by 4 numbers and the 4 numbers of each column to the 4 different arrays, so if I read from the data above, i get an array with numbers 1,5,8; another with 2,6,9 and so on. Is it how its done in my code?
start writing a program to store some information and then have it recalled. I would like to be able to store a list of the video games I own because i thought it would be fun :)
I am doing a programming assignment. This program asks you to collect statistics on precipitation and temperatures from the four quarters of a year and print the calculated results. It is an exercise in using enumerated types and arrays. The measurements are entered at the end of every quarter.
Major variables (there are other variables) in the program: Variable called: month of type Summary_Month (the enumerated type) Arrays of integers called: low_temp, high_temp, precip Array of doubles called: avg_temp
You will ask the user to enter the precipitation, low temperature and high temperature for each quarter. As you gather this data, you will calculate the average temperature (using avg_temp) for each quarter by averaging the low and high temperature for that quarter.
After you gather the information you will calculate and output : Total Precipitation for Year, Average Quarterly Precipitation, Average Quarterly Temperature, Highest Temperature for any quarter, Lowest Temperature for any quarter.
I am not getting the right output for average precipitation and temperature and I am not sure how to determine the highest and lowest temperature.
# include <iostream> # include <iomanip> using namespace std; enum Quarters { March, June, September, December}; int main() { const int NUM_QUARTERS = 4;
Trying to do a homework assignment for a class and how to read a file into an array. I've looked in our book and on several other forums and cant seem to find any examples of this. Below is the assignment I'm working on. I have a shell of the program that I can get to run, but getting a .txt file to read into an array is something I cant seem to figure out how to do.
Write a program to read N data items into two arrays, X and Y, of size 20. Store the product of the corresponding pairs of elements of X and Y in a third array Z, also of size 20. Print a three column table that displays the arrays X, Y, and Z. Then compute and print the square root of the sum of the items in array Z. Compute and print the average of the values in array Z and print all values above the average of array Z. Determine the smallest value in each array using only one function.
Use the two data files named DATAX.TXT and DATAY.TXT.
You must use functions for the reading of the data, computing the average, printing the three column table and printing the values above average.
