C/C++ :: How To Pass Multiple Values From One Function To Another
Mar 4, 2015
I need to pass multiple values from one function to another and how to do this. Here is my code so far.
#include <iostream>
#include <string>
#include <cctype>
#include <fstream>
using namespace std;
//Function Prototypes//
int charString(string, string, string);
string reverseString(string, string, string);
[Code]...
I basically need to take line1, line2, and line3 and return them to the reverseString function. Also, I am not allowed to do anything like make my own classes. I have to stick to the basics and no higher level programming techniques since we have not learned them yet.

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 returning area from areaCircle(), but do not know how to print it in main. I know this program has lots of errors, two cases that I have listed.
Not sure how to properly list multiple function calls in a switch statement, and how to print one's return from main.
int main() {
char choice;
double area;
showMenu(choice);
switch (choice) // If input is C, use getRadius, areaCircle and count, then print the are
{
case 'C': void getRadius(),double areaCircle(), void count(bool display = false);

I built a program that finds the average amount of days missed per employee. I am now attempting to modify my program to pass values by reference rather than passing by value. I created 3 functions: int numOfEmployees(); int numOfDays(int); double avgDays(int, int);
in the prototype I use the ampersand sign int numOfDays(int&);
in the actual function I use numOfDays(int& employees)
I am just not able to get the call to the function to work the program will crash when I modify it with the ampersand signs.This is the original code I am trying to modify:
#include <iostream>
using namespace std;
int numOfEmployees(); //Prototype for numOfEmployees
int numOfDays(int); //Prototype for numOfDays
double avgDays(int, int); //Prototype for avgDays

Well I know how to pass values between forms using get and set properties. But the problem with it is everytime I want to pass values from form2 to form1 it doesn't appear. To make it appear I have to type form1.Show(); which open form1 a second time and then show the value. Is there any way I could make it appear without using form1.Show();?

This code is for fun, and have it doing a lot of what I want it to, just not all. I want random generated to write to a txt file. I tried to use an array but that failed. I wanted to use an array because i am only passing one value. Which makes sense since the random generated function is an int.
I made the fprintf as a comment but hopefully soon it will be able to send the values to the txt file. After that I will tackle the function.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#define HIGH 49
#define LOW 1
int random_generated()

I am using a struct and tying to send values to it as byte value
Code:
#include<stdio.h>
typedef struct{
unsigned r1:1;
unsigned r2:1;
unsigned r3:1;
[Code] ....
Error: invalid suffix "b00100000" or incompatible types in assignment
I am able to access the member as Range.r1 = 1; and have no problems. I want to send data whole at once, but how ?

I would like to return multiple values from one function to access in different functions. For example:
int function1(//what goes here?)
{
int a ;
a = 1 + 2 ;
int b ;
b = 3 + 4 ;
return (what goes here if i want to return the value of a and/or b to use in another function?) ;
void function2()
{
//now i want to use the value of a here to use in an equation, how do i do that?
//now i want to use the value of b here to use in an equation, how do i do that?
}

I am working on a text based RPG. As with most RPGs the character has attributes that grant modifiers. Lets take strength for instance. Suppose the character can have a strength score that ranges from 1 to 10. Based on strength the modifiers could be like the following:
Strength = 1 grants +1 to hit and +1 damage
Strength = 2 grants +1 to hit and +2 damage
Strength = 3 grants +2 to hit and +3 damage
I want to set these values at design time and be able to retrieve the modifiers based on the strength value from multiple places in my program.
What is the best method of designing this. I looked around online and saw references to Lists with Tuples and Dictionaries with Tuples but these did not seem to be a very efficient way of handling the scenario above.

I would like to have 2 functions. (FYI, I haven't even tested these because I don't have a compiler on this PC, so don't know what they'll do. I'm also new to C++, self-teaching.)
My question is, I'm sure that oFile should be type object (of some sort), not int, but I'm not sure how to reference it correctly so that it passes from FileOpen to main to FileClose.
Code:
#include <iostream> //I/O
using namespace std;
#include <fstream> //files
using namespace ios;
int FileOpen(string fileName) {
ifstream oFile (fileName); //attempt to open file

I used to use map to access elements. map has a good feature that it sort the element automatically. Now I need a map which can access element through multiple key values. So I choosed boost::multi_index_container. I defined a container as follows.
struct elem {
int a,b;
elem(int aa,int bb):a(aa),b(bb) {}
};
typedef multi_index_container <
[Code] ....
What I am wondering is whether boost::multi_index_container can sort elements automatically. Specifically, are all elements extracted through iterator from begin to end shown below having b values between 2 and 100?
test t;
test::iterator begin = t.lower_bound(make_tuple(1,2));
test::iterator end = t.upper_bound(make_tuple(1,100));

I wud like to delete multiple values from a vector using indexes as my values r not fixed they may change so using indexes i want to delete
For example: vector<int> v={1,2,3,4,5};
I want to erase 3,4,0 indexes
So resulting vector is 2,3

So I have to write a code for my C++ class, and I am having a problem trying to figure out how to get my code to read multiple int values. This is what my code should look like
Enter two times in military format (e.g., 1730 1520): 1730 1520
[1520<1730]
Enter two times in military format (e.g., 1730 1520): 1520 1730
[1520<1730]
Enter two times in military format (e.g., 1730 1520): 1730 1730
[1730==1730]
Enter two times in military format (e.g., 1730 1520): 1760 1520
1760: [INVALID TIME 1]
Enter two times in military format (e.g., 1730 1520): twelve 2
[INVALID NUMERIC INPUT]

I have an XML document, formatted as such:
<?xml version="1.0" encoding="UTF-8"?>
<Books>
<Bookmark Name="1984" Folder="C:UsersmillerDownloads1984 (George Orwell) - Audio Book" Time="00:43:58.4080000" Chapter="0" />
</Books>
Each Element named Bookmark has 4 attributes, Name, Folder, Time, and Chapter.
I'd like to be able to just put all of them in ONE type of container, without making multiple lists... Is there any way, using Linq to XML, to maybe add all of these values to a Tuple?

#include "Header.h"
#include "Orange.h"

So I have this text file that I am trying to read from and store the values of each line in multiple variables. Let's say my text file contains
AXSYZ3482 Tom 100 112 and my code below here works fine when the lines in the text file is separated by spaces.
Code:
while (fscanf(fp, "%s %s %d %d
", userID, name, &startLoc, &endLoc) != EOF) {
printf("%s %s %d %d
", userID, name, startLoc, endLoc);
}
But let's say my file was to look like this instead.
AXSYZ3482:Tom:100:112
But if i try this below...
Code:
while (fscanf(fp, "%s:%s:%d:%d
", userID, name, &startLoc, &endLoc) != EOF) {
printf("%s %s %d %d
", userID, name, startLoc, endLoc);
}
It seem to store the entire line in userID including the ":". I want to ignore the ":"'s and store everything in between in respective varibles in the order specified above.
So first string in userID, then ignore the :, then second string in name, and ignore the next :, and so forth.

How difficult would it be to program a hash-map system where each "key" can have multiple values under indexes?
For example: "Word" -> 45(index 0) , 67(index 1) , 12(index 2). What could I start with to program this or where could I find a pre-made system that does this?

In this program, I have to ask the user for an employee, then the program will check to see if the file for that employee exist, if it doesnt then it will automatically create the file.
ReadNew function reads the file....check to see if it exist
CreateNew function creates a new file.
In my code I have no problem with the first part of reading file.. and my createnew function works in other programs where I am asking for input of file name to create the file name. However in this code I cannot figure how to automatically pass the input filename from the ReadNew function to the CreateNew function. I can't ask the user to enter the name a second time, so I have to pass the input filename into both functions
Here is my code.
Code:
//Create a file, append to it, and read it.
#include <iostream>
#include <fstream>
#include <string.h>
#include <stdio.h>
using namespace std;
char filename[256];
string n;
string filelist;
void CreateNew(ofstream & FileNew);

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... :(
