C :: Function That Merge Content Of Two Sorted Arrays Of Double Type Values
Nov 4, 2013
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 have to merge two sorted files. Algotrithm that i'm using is below, but it reads not all the numbers in the files, and stops, even the files contain the same number of elements. What is wrong, I can't understand.
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'm trying to pass 2 arrays into a void funtion, and return values to one function.
this is the the program I'm working with, after I'm done I have to split it into 3 files, a header, a main, and a separate cpp file for the functions to live in.
#include <iostream> using namespace std; void processArrary(int numberCount[], int Numbers[], int intnumberSize, int numberCountSize); int main() { int Scores[26] = {76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189}; int numberCount[8] = { 0 };
[code]...
The goal of this program is to separate and count the groups of numbers then output the amount of numbers in each group. Near as I can tell, everthing should work, but I'm getting all zeros to be displayed in each group.
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 wrote this code for a homework assignment, everything runs fine but the function void percent_votes (line 66) isn't calculating properly, it outputs 0.00 for each value. I have tried everything I can think of to try and make it work.
Here is the assignment: Write a program that allows the user to enter the last names of five candidates in a local election and the number of votes received by each candidate. The program should then output each candidate's name, the number of votes received, and the percentage of the total votes received by the candidate. Your program should also output the winner of the election.
I'm trying to write a code that takes two arrays from the user (presumably in ascending order) and then passes the sizes of both arrays and a pointer to each to a separate "int* mergeArrays" function that will merge sort the two. I've written a lot of the code, but I can't get it to compile. I get errors: lab6.c: In function "main":
lab6.c:31:14: error: expected expression before "int" mergeArrays(int* firstArray, int size1, int* secondArray, int size2); ^ lab6.c:31:14: error: too few arguments to function "mergeArrays"
Code: #include <stdio.h> #include <stdlib.h> int main() {
[Code].....
he problem is that when I print out the three sums at the end of the program I dont get any decimal points but just zeros like something.00 instead of something.50 etc
The main is not working properly, I get strange missing parenthesis notices and array errors which I am not understanding. How to identify the errors. Functions are included.
Code: #include <stdio.h> #include <stdlib.h> #include <string.h> int menu (); double change_value (double * value);
Can you use data type double or float for an array? ie
double n[]; or float a; float m[a];
My code wont accept me changing the data type..will on accept int data type. I get the following error when I try to change the array to double or float..
3310E:C++vector.cpp[Error] invalid types 'double [1000][double]' for array subscript
How to pass my array to the function and return it as a sorted vector. I'm kind of lost with the functions part.
Problem: Write a program that performs a sorting routine as discussed in class. Create an array of 10 integers (e.g., 63, 42, 27, 111, 55, 14, 66, 9, 75, 87). Pass this array to a separate function that sorts the integers and returns a vector containing the sorted integers. Use either the SELECTIONSORT algorithm or the INSERTIONSORT.
Using a for loop, construct two 100 element arrays, x and y, such that element i of x stores the value sin(2*pi*i/100)) and the corresponding element of y stores cos((2*pi*i/100)). Print the values stored in the elements of x and y as you calculate them.
I have attempted to solve it but I'm not sure why the value 0 is only being printed, maybe I haven't assigned sin(2i/100)) and cos((2i/100)) to the arrays properly?
Code: #include<stdio.h> #include<stdlib.h> #include<math.h> int main () {
while (getline(inStream, line)) { while (inStream >> Student.getId() >> Student.FNAME >> Student.MINIT >> Student.LNAME >> Student.GENDER >> Student.UNITS >> Student.getGpa()) { while (Student.getId() != id) { outStream << line << endl; } } }
This is what I have right now. It shouldn't be a problem, but for some reason I am getting an error trying to >> Student.getGpa()

I will post more code if needed, but... I just don't know. I have a TON of code so I would rather not if I don't have to.
The following code compiles and runs fine till it reaches line 16 and gets a sigsev violation which I'm not sure about as to why. I have no problem passing the object of type node** into the constructor of base and storing it into the double pointer node** copy;; but when I call the function void pass(node** temp) it crashes.
#include <iostream> class base; class node { private: node** data; public:
I have std::vector of players and each player have its own value. The value is of the type double, but the original value are of the "XX.00".
Now what I'm trying to do is to insert a player into this vector. For that I need to find a place and to find a place I need to compare player value.
So lets say I have a player in the vector whose value is 24.00 and I am trying to insert a player whose value is 25.00. To my surprise MSVC 2010 tells me that:
24.0000000000000 == 25.00000000000
I do aware that comparing double type is not going to work like this, but I would expect not to have such big of a difference. ;-)
Why this comparison is true and how to eliminate such thing?
Where col is a 'vec4' struct with a double[4] with values between 0 and 1 (this is checked and clamped elsewhere, and the output is safely within bounds). This is basically used to store rgb and intensity values.
Now, when I add a constant integer as a pixel value, i.e.:
buffer_rgb[i] = ((unsigned char)255;
Everything works as it should. However, when I use the above code, where col is different for every sample sent to the buffer, the resulting image becomes skewed in a weird way, as if the buffer writing is becoming offset as it goes.
You can see in the 'noskew' image all pixels are the same value, from just using an unchanging int to set them. It seems to work with any value between 0-255 but fails only when this value is pulled from my changing col array.
Whole function is here:
// adds sample to pixel. coordinates must be between (-1,1) void Frame::addSample(vec4 col, double contrib, double x, double y) { if (x < -1 || x >= 1 || y < -_aaspect || y >= _aaspect) {
