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:
Code:
#include<stdio.h>
void merge(int firstArray[],int secondArray[],int size) {
int mergedArray[size],i=0,j=0,k=0;
while(i<size||j<size) {
if(i==size) {

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 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 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>".

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.
Example text file contents:
values;data
5.01 100
2.9 342
2.69 43534
10.1 43
6.8 45324
Output: Text file containing
2.69 43534
2.9 342
5.01 100
6.8 45324
10.1 43
It's easy to do this if there was only 1 number on each line, but I do I sort all the lines based on the first number in each line?
Whenever I run my program, It should be taking this string of information:
Shampoo 10 8.75 87.50
Pen 3 2.50 7.50
Headphones 5 20.99 104.95
MacAir 1 879.23 879.23
Raspberries 6 4.99 29.94
Oranges 5 2.79 13.95
Apples 3 3.85 11.55
From one file and outputting it to another, the finished product should look like:
Shampoo 10 8.75 87.50
Pen 3 2.50 7.50
Headphones 5 20.99 104.95
MacAir 1 879.23 879.23
cheapest item = Pen
most expensive item = MacAir
total cost = 1079.18
shopper = Mary Kay
Raspberries 6 4.99 29.94
Oranges 5 2.79 13.95
Apples 3 3.85 11.55
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?

and you needed to inset the number 11 into the file and keep it sorted.
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

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 cannot figure out what is wrong at the moment. .
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;

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);

Here's my code:
struct Member {
char *name;
char *address;
char Interests[][10];//<------problem
int numofInterests;
Numbers digits;

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.

So far i tried using fscanf()
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <stdbool.h>
#define DEBUG true
#define CHECK true

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..

44 5 8 = sum
43 4 7 = sum

but that isn't the issue right now..
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 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.

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.
