C++ :: Finding Sum Of Two Fractions - Return Array In Function?

C++ :: Junk Return On Passing Array From A Function
Apr 23, 2014I 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>

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 )....
C++ :: Array Data Loss After Return From Function
Oct 2, 2013I 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

C++ :: How To Pass Array To Function And Return It As Sorted Vector
Sep 17, 2014How 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>

C++ :: Write A Function That Return Maximum Value Of Array Of Doubles?
Oct 9, 2014I'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...
C :: Why Integer With Array Change After Passing Through The Function
Apr 12, 2014Code:
#include <stdio.h>
void define (int integer, int IntArr[0], int *IntP);
int main(void)
{int integer = 0, IntArr[1] = {0}, IntP = 0;
define(integer, IntArr, &IntP);
[Code]...
Why does the integer with array change after passing trough the function and the normal integer doesn't? (I know why the normal one doesn't, but I dont get the array one)
C++ :: Function That Stores Number Into Integer Array?
Apr 30, 2013I'm writing a function that stores a number into an array. If the number is greater that the lowest number in the array then it replaces it. The array size is 10. When the number is stored in the array. The lowest number must then be remove.

Mar 29, 2013I'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.

C :: Create Array Of Integer - Function Call In Main
Feb 2, 2015I'm writing code to create an array of integer and let user input choice to display, replace, add new element, etc.I created a header file in the header file there's a function:
Code:
int display_one_element(int* array, int num_of_elements, int position) {
if(num_of_elements < position || position < 0) {
printf("Position out of bound.
");
return 1;
}
return array[position-1];
}
in main I write a function call:
Code:
display_one_element(array, *p_num_elements, position);
My code seems to work fine but there's an error message right next to my function call:
1.too many arguments provided to function like macro invocation
2.Expression result unused
I tried to move the function from header file to c source file. but other functions in the header file works fine and this doesn't work with the error message.

C/C++ :: Dividing Two Integers Will Return Integer Value?
Dec 2, 2014So I have a simple calculator that does a few operations (+ - * / %) Pretty basic stuff
I declared int x, y for the numbers, char operation, and float result.
the code is based on switch(operation)
The program is running alright, but when I divide 8/7 it returns 1 as the result, I tried changing the x and y to float but that won't work because of the case '%'
I also tried making local float variables in the case'/' but it won't compile "E2126 Case bypasses initialization of a local variable"
How can I make the division work and return a float value?
C :: Write A Function That Finds Integer In Array And Returns Its Corresponding Index
Mar 20, 2013I 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;

Example, if user input is 4 (index) and the integer equals 123456790 the return value for the function is 5 (start index at 0) ; if user input is 40 (index) and the integer equals 123456790 the return value for the function is -1

C :: Warning - Return Makes Pointer From Integer Without A Cast
Sep 21, 2013I have a function that I want to exit gracefully when an "error" occurs in an input file. My function declaration is:
Code: BSTnode *buildTree(FILE *fp)
The few lines that are causing the problems are:
Code: if(regcomp(®ex, to_find, REG_EXTENDED | REG_NEWLINE) != 0) {
fprintf(stderr, "Failed to compile regex '%s'
", to_find);
return EXIT_FAILURE;
}
I know that if I just use "return" by itself the warning goes away but fails to exit when the error occurs. I also believe this may not be the correct use of stderr. But I need the program to exit when an error has occurred.
C :: Assign Integer Value To Unsigned Char Array But It Is Not Storing Integer Values
Oct 25, 2013I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet
Code: uchar uc[100];
for(i=0;i<100;i++)
{
uc[i] = i;
}
The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.
C++ :: Pass 2 Arrays Into Void Function And Return Values To One Function?
Feb 12, 2014I'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.
C :: Main Function Does Not Return Any Values When Calling Other Function?
Jun 9, 2013The 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.
