I'm writing a function that is to return the price of something.. What would be the most appropriate return type for this? Like in Java it would be a double...

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;

I want this programming to call functions choose between a customer type and call the relevent function to calculate the final price but it is not calling the functions.
#include <iostream>
using namespace std;
double amount;
double studendOrPensioner(int&choice, double &origPrice);
double OtherCustomers(int&choice,double& origPrice);

Create a user-defined program that will compute the price per square inch of a cake using an “overloading”. The cake could be a circle or a square type. In the main function, ask for the price of a circle cake and its diameter, while for the square cake, ask for the price, its length and width. The process must be done inside the different function of each cake. (Note: two sub function for the computation of a circle and a rectangle)
Note that when I made this program something weird happen. After inserting the name, all things follow.
<code>
#include "stdafx.h"
#include <iostream>
using namespace std;
double areaRectangle(int l, int w);
double radiusCircle(int r);

I have a function that returns a char*. No problem. But I need to concatenate another array with the results of this function. I'm getting a segmentation error.
Code:
//this next line outputs correctly so I know my function is working
fprintf(stdout, "%s

char* temp;

For a Homework i need to make some kind of Minesweeper but i have one Probleme one of my functions always return teh same and i cannot fin out why here is the code:
bool setzen(int x, int y){
if(feld[x][y]!=3){
return mine=false;
}
[Code]....
Thats the Part where Everything happens but the Function "bool setzen" always returns false and i dont know why.
How can I show elements of a vector that is returned by a function in main() ?
Code:
vector<int> merge_sorted(vector<int> a, vector<int> b){
vector<int>temp;
int count = 0;
if(a.size() < b.size()) count = a.size();
else count = b.size();

to return the array i shall make a pointer function thats ok.. but how do I get the size return if i dont know the size?
if I need to make AXB=C and output C my new array doesnt have a size..
Is it possible to create a function that can both return and display a value. I was trying to make a program that computes and prints terms of the Fibonacci series using a recursive function.
View 3 Replies View RelatedI am writing a program with a function that includes a long loop. I need this function to return a value when each loop is done, to send this value to output, in order to follow the progression. But I don't know how to do it in easy way. The function is like follow:
int goC(){
... // some local value definition
for(int i = 0; i < 1000; i++){
... // a lot of calculations done here
return i; // -> return the value after each loop is done
}
}
Here it only returns one value, i = 0. Clearly it's wrong.
I'm writing some functions pertaining to binary trees. I've used recursion once before while learning quicksort but am still quite new and unfamiliar with it. And this is my first time touching a binary tree. So my question: In my addnode function, will the return root statement at the end ever return a value other than the value passed to the function?
Code:
#include <stdlib.h>
struct tnode
{
int data;
struct tnode * left;
struct tnode * right;
}

I need to make a program that returns pascal's triangle of N rows. I actually need to make a function of format "int **func(int n)". I don't know how to go about that, so I am trying this method first, but I seem to be getting an endless loop.
Code:
#include <stdlib.h>#include <stdio.h>
int *rowN(int rowNum, int* prevRow) {
int *rowN;
rowN=realloc(rowN,(rowNum+1)*sizeof(int));

How to go about making a function that accepts an integer and returns a string with any one of 5 strings containing the name of the object. For example object number 3 might be "Pen". Object 4 might be "Paper".
To do this would I just use an array?
I need to create a function that takes as an input a variable number of scalars and returns the biggest one. Just like std::max() does for 2 elements, but I need it for an undefined number of elements, can be 2, or 5, or 10 etc.. How to approach this?
What I need it for: I'm working with a bunch of vectors, maps, etc. and I need to find out which has the most elements. So I was thinking that I should end up with something like
int biggest = max(vector1.size(), vector2.size(), map1.size(), ...);
I have a big problem with a function, I wrote this function in order to get a line from an HTML (Or XML) file, until a specified delimiter (not always or
... It can be everything..)
Here is my code :
public static String GetLineUntilChar( String url , char delimiter , String postData, String referer, String cookie ) {
try {
Uri uri = new Uri("http://127.0.0.1//site.html");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.ContentType = "application/x-www-form-urlencoded";
if (!String.IsNullOrEmpty(referer))
request.Referer = referer;

I having some issues with two different programs here... One of them crashes and returns random negative numbers whenever it reaches a "fscanf" function and the other displays a "Polink fatal error: access denied" error.
Code:
/* Evan Wentz */
/* Pike - ET2560 */
#include <stdio.h>
#define MAX_ACCTS 100
int accounts [];
double balances [];

I thought the reason this kept crashing before was because I didn't type the data into the text file it was writing too correctly, but I made another program to do that, and it crashed whenever it got to fprintf. Program works perfect besides the file stuff...
I have a matrix that contains zero and nonzero elements. I want to do a function that return 3 arrays.
The first one is for nonzero elements the second array contains the corresponding row numbers of each nonzero element the third array contains the corresponding column numbers of each nonzero element.
Write a function that computes and returns the score for a permutation, i.e. the number of reversals required to make arr[0] == 1.
HAVE TO USE FOLLOWING FORMAT:
Code:
// POST: Returns the number of reversals needed to make arr[0] == 1
// if the reversal game were played on arr
// Note: If arr[0] == 1 initially, then score(arr, n) returns 0 AND this is what i could muster;

I have an assignment which requires me to do the following:
Required to write a function that finds an integer in an array and returns its corresponding index. The function must be called findNumber. It must have FOUR parameters:
- The first parameter is the array to be searched
- The second parameter is the integer to be found within the array
- The third parameter is the size of the array
- The fourth parameter is an integer that indicates whether the array is sorted. A value of 1 means the array is sorted; a value of zero means the array is not sorted.
Since a function can only return one value(To return the position of a required integer in an array in this instance) I have tried to make use of pointers to try and return a value stating whether the array is sorted or not.This is my code : (It compiles perfectly but it does not produce any outputs)
Code:
#include <stdio.h>
#define SIZE 10
size_t findNumber(int *sort, const int array[],int key,size_t size);
int main(void){
int a[SIZE];
size_t x;

The question is to write a recursive boolean function that compares two stacks and returns true if they are identical. This is where I get stuck:
If the top items of both stacks are the same, the recursive call always returns true, because 'true' is saved on top of the return stack.
Here is my code:
template<class Type>
bool identicals(stackType<Type> s1, stackType<Type> s2) {
if(!s1.isEmptyStack() && !s2.isEmptyStack()) {
if(s1.top() != s2.top())

I would like to make a program for calculating the total price of a game station, and a game. I made a program like this for just the price of a game in class, but I want to make one that does the game system as well.

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() {

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.
The function is supposed to return value from the file in my main, but I am getting empty value. I am trying to get better with pointer. Right now just teaching myself.
right now the only way for this code to show value is when in put the putchar(*ps) inside my readfile function. I would like to readfile to return value and print in the main function.
Code:
#include <stdio.h>
char *readfile(char filename[]);
int main(int argc, char *argv[] ) {

Is it possible to have more than 1 return value from a subprogram?
