C++ :: How To Pass Array To Function And Return It As Sorted Vector
Sep 17, 2014
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.
Code so far:
#include <iostream>
#include <string>
#include <vector>
#include <cmath>
#include <cstdlib>
#include <ctime>
#include <iomanip>
[Code]...

Objective: Write a function with the given signature that will take a sorted array of integers and return the array compacted. That is, given an array containing: 1, 2, 6, 8, 8, 8, 9, 10, 10, when the function returns, the contents of the array should be: 1, 2, 6, 8, 9, 10.
Restrictions:
Cannot use Distinct method
Signature:
public static int[] CompactArray(int[] input)

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.

How to do i fix this code im not good at using function, im trying to pass a statement from switch to my double passengersR i always come out with a error
this output:
Name passenger:
Enter number passenger:
Choose from A to D
if choose A
Total Regular Passenger: 6.19624e-312
did i do something wrong im not really good at function and im trying to learn how to pass switch to void function
Code:

My function has the following prototype:
std::vector<double> calculate_mag_response(double start_freq, double end_freq,
int N, std::vector<double> num, std::vector<double> den
The function should return a vector size N of magnitude responses in decibels of the transfer function defined by numerator and denominator vectors num and den. To adequately test, you should drive this with more transfer functions.
#include <vector>
#include <iostream>
#include <cstdlib>
#include <ifstream>
using namespace std;
int main(int argc,char *argv[]) {
vector<double> myNum, myDen, results;

Okay, so for an assignment I need to write a function called find() that returns a reference to a vector. So I have vector <int> & find(string & key); If I do this, I get the obvious warning warning: reference to local variable 'lineNum' returned [enabled by default].
If I do vector<int> & find(string & key) const; I get a huge error that starts out like
In member function 'std::vector<int>& index_table::find(std::string&) const':
indextable.cpp:74:30: error: no match for 'operator='
Am I using the const identifier incorrectly?

I have vector pair like below, it is sorted but I want to remove duplicate values: The vector is like below:
std::vector<std:air<std::string,double>> fileWeight;
Here is what in vector:
scene1.jpg 0.4
scene2.png 0.4
scene3.jpg 2.3
scene4.jpg 4.1
The highlighted top 2 are duplciated. How can I remove duplciated like this where I have to check whole pair?

There appears to be some kind of error in by removeMin() function. Inserting items seems to work just fine but attempting to remove any items gives me the error "vector subscript out of range".
Here is my SortedPQ class... Below it you will find the quicksort implementation, in case looking at it is necessary.
template <class Type>
class SortedPQ {
private:
int front;
int rear;
vector<Type> V;
public:
SortedPQ(void) : front(-1), rear(-1), V(0){}

I'm trying to pass an array from one function to another without resorting to pointers and I have to use Pass by Reference. I can't seem to figure it out. I've been looking at many examples and just don't get it.
the function createAbc makes an array populated with the Alphabet. I need to pass that into my display function so that i can work with the array there. I don't know how to pass it in there... :(
#include "stdafx.h"
#include <iostream>
#include <cctype>

How would I pass let say 2 array pointers to a function X , allocate memory for them in X , fill them with values and get them back in my main function without creating a structure.
example:
Code:
void X(int *a, int*b){
a= malloc ...
b = malloc ...
// fill a and b
return them back to the main function
}
void main(){

I have been working on this all day, and its due in like an hour and a half. I have done everything the program wants except the last part. Here is the assignment:
Write a program that inputs 10 integers from the console into an array, and removes the duplicate array elements and prints the array. You may assume that all the integers are between 0 and 100, Write at least 1 function in addition to the main function, and pass an array into that function as a parameter. e.g.
Please enter your 10 numbers: 1 2 3 4 5 6 7 8 9 10
The array contains: 1 2 3 4 5 6 7 8 9 10
Please enter your 10 numbers: 1 1 3 3 3 6 7 8 9 9
The array contains: 1 3 6 7 8 9
Please enter your 10 numbers: 1 1 1 1 1 1 1 1 1 1
The array contains: 1
The bolded part is what I cant get to work. I have tried this and it keeps telling me I have not identified the items when I have.
Here is my code:
#include "stdafx.h"
#include <iostream>
using namespace std;
[Code]....

If a function takes N-dimensional array as a parameter, what is generic way to do that? I couldn't figure out a nice way to do that.

I have a cpp app that reads in a number of files and writes revised output. The app doesn't seem to be able to open a file with a ' in the file name, such as,
N,N'-dimethylethylenediamine.mol
This is the function that opens the file :
Code:
// opens mol file, reads in rows to string vector and returns vector
vector<string> get_mol_file(string& filePath) {
vector<string> mol_file;
string new_mol_line;
// create an input stream and open the mol file
ifstream read_mol_input;
read_mol_input.open( filePath.c_str() );
[Code] ....
The path to the file is passed as a cpp string and the c version is used to open the file. Do I need to handle this as a special case? It is possible that there could be " as well, parenthesis, etc.

I have this code:
const BYTE original[2][4] = {
{0x00, 0x00, 0x00, 0x00},
{0xFF, 0xFF, 0xFF, 0xFF}
};
void function(const BYTE** values){
[Code] ....
You might notice that the above code doesn't compile, this is the error:
cannot convert parameter 2 from 'BYTE [2][4]' to 'BYTE *'
1>
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
Even after some search I couldn't really find an answer to my problem, how do I pass the const BYTE array which I declared above in the function as a parameter (or what structure do I need to set for the function as a parameter)?

I passed an array from a function from a class and i am using the object of that class in other file but when i pass it the values of that array are coming ssome junk values (i think) i ll show u the usage :
// randomno.cpp : Defines the entry point for the console application.//
//#include "stdafx.h"
//#include<iostream>
#include<ctime>
using namespace std;
class randomnogen {
[Code] ....
Then I used it in my main file like this:
int* Q_Rand = &o_random_gen.generate();
o_SciTech.showQuestion(Q_Rand[i],main_quesfname);
The value of Q_Rand comes out to be some very large value sometimes negative sometimes positive (i.e a junk )....

I have an object that I use to store data. Two of its members are dynamic arrays. When passed (by reference) to a function used to fill the arrays with data, everything works fine. However, only the 0th index of the arrays remain populated after the function call.
parameters.cpp // class reference
#ifndef parameters_H
#define parameters_H
using namespace std;
class parameters {
public:
double k;
double c;
double a;
double vci;// Cut-in velocity

I'm trying to get correct answers from my exam to study for a midterm:
Write a function that returns the maximum value of an array of doubles.
Declaration:
double maximum(array[],int a_size);
So far I've done:
double maximum(array[], int a_size) {
double maxVal;
maxVal = array[0];
for(int i=1; i < size; i++) {
if(array[i] > max
maxVal=array[i]
}
return maxVal;
}
I just need any corrections.
Second, I need to write a function definition that merges two vectors containing integers, alternating elements from both vectors.
Prototype:
vector<int> merge(const vector<int> a, const vector<int> b);
This is my definition so far:
vector<int>merge(const vector<int> a, const vector<int> b){
vector<int> merged;
for(int i=0; i<a.size+b.size; i++) {
if(flag == true)
merged.push_back(a);
flag = false;
else
merged.push_back(b)
flag = true;}
I think I'm lost in the second part...
