C++ :: Function That Takes Two Input Arguments And Provides Two Separate Results To Caller
Apr 20, 2014
Write a function that takes two input arguments and provides two separate results to the caller, one that is the result of multiplying the two arguments, the other the result of adding them.Since you can directly return only one value from a function, you'll need the second value to be returned through a pointer or reference parameter.
Code:
#include "Code.h"
#include <iostream>
#include <string>
double x, y;

How do I Write a function that takes two linked list as input arguments these linked list contain numbers like this:
num1->3->5->2->NULL (assuming that number 1 is 352)
num2->4->3->9->1->NULL (assuming that number 2 is 4391)
The function should return 1 if num1 points to a linked list which represents a smaller number than the number pointed to by num2 linked list. Otherwise, it returns -1. If both linked list point to exactly the same number, returns a 0.

I keep getting this error in my code. I believe it is because to use pow(x,y) both x and y have to be double, but how do i put that into my formula under calculations?
#include <iostream>
#include <cmath>
#include <iomanip>
#include <string>
#include <fstream>
using namespace std;
int main() {
// Declaration section: Declaring all variables.

I need to do it to avoid calling a function of my process from injected code.
So would like to hook this function to check whether the call is from the current module or it is from an external module, then I compare the address of the instruction who did the call with the module address range.

I am having trouble creating a new User from my User Class. The error I am recieving:
Error3'HospitalSystemBL.User' does not contain a constructor that takes 2 argumentsC:UsersStudentdocumentsvisual studio 2010ProjectsHospitalSystemHospitalSystemLogin.aspx.cs2131HospitalSystem
In my User class, I have two constructors. Default and an overloaded constructor.
//default constructor

I am trying to create my user in my Login class. Why is the error saying "does not contain a constructor that takes 2 arguments" when I have a constructor (above), User passing two arguments: UserName and Password? Here is my code for the login:

I'm just getting back into the swing of things after a long time of not programming. I'm trying to create a program which takes in command line arguments and prints the last one. My code is as follows:
#include <iostream>
#include <vector>
#include <string>
using namespace std;
int main() {
string x;
vector<string> arguments;
[Code]...
And the error message I receive, a simple but frustrating one, is as follows:
Enter arguments, enter STOP to stop: Segmentation fault...

I'm writing an addition and subtraction calculator that takes input as: 5+6-3+2. You should be able to add or sub as many numbers as you want. I want the while loop to stop when the user hits enter. I put the getchar() function to catch the and break the loop but it is also swallowing the '-' sign, which I want to use to subtract and is instead adding the numbers with "sum+=number". How can I get around that?
Code:
#include <stdio.h>
int main(int argc, char *argv[]){
int number, sum = 0;

I am using VS2K12 version 4.5.50709.
I am working Prata's C++ Primer 6ed. The exercise sequence of Listing 6.9 through Listing 6.11 involved using a switch statement with integer input (switch.cpp: 6.9), character input (switchchar.cpp: 6.10), and using integer input with enum (enum.cpp: 6.11). The main function of each was similar, especially in the usage of the input variable used by cin ("code" in the code provided below).
With switch.cpp, it was shown that entering a character caused the loop to cycle continuously. This was because the "cin >> choice" call failed to read the character into the int (choice) variable. The 'cin.fail() test followed by cin.clear().get() was added to switch.cpp to prevent the bad read from producing the loop spin.
However, in the original version of enum.cpp (below), which also uses integer input, if I input an 'm', the response is:
Enter color code (0-6): m
Bye!Press any key to continue . . .
In other words, with character input the int based read operation apparently did not fail. The main methods were very similar, but I noticed that switch.cpp used the "!=" operator in the while loop's test expression. So I tried it in enum.cpp and it is commented out in the code below. I found that with that code in place the inability to handle character input was present. When a character is input the failing response is:
Enter color code (0-6): Always include default case.
Enter color code (0-6): Always include default case.
Enter color code (0-6): Always include default case.
...
...
I assume this is a VS2K12 quirk, but I will likely try something like gcc at work tomorrow. I think it would be easy to chase this though the iostream code, for someone who has already been there. But it is going on 1AM, and I am not certain it would be time well spent (i.e. how often do you "really" need to debug iostream code?). I did use the debugger and see that (I believe) _OK is set to false.
// enum.cpp -- Listing 6.11 (PG 279): Using enum (091513)
#include <iostream>
// const int red = 0, orange = 1, ....
enum {red, orange, yellow, green, blue, violet, indigo};
int main() {
using namespace std;
int code;

I have a menu for a project that takes a string input and does whatever option you specify. It works perfectly EXCEPT when it goes through the while-loop (while you didn't say quit the menu reloads). It will spew out all the text in the menu like a bulimic teenager. Then it reloads properly and asks you for an input like nothing happened. While this is not a fatal error (code still functions)...
Code:
#include <stdio.h>
#include <math.h>
#include <string.h>
double aa=0, ab=0, ac=0, sa=0, sb=0, sc=0;
char a1[13], o1[]="AAS

I have to make a program that takes a number input from the user and prints the corresponding fibonacci sequence number. For example, for the input of 3, it should print 2 since the third term in the fibonacci sequence is 2.
I am not sure how to do this so for my attempt, I used the formula found in this website. A Formula for the nth Fibonacci number
Here is the program so far. It doesn't produce the correct output.
Code:
#include <stdio.h>
#include "genlib.h"
#include "simpio.h"
#include "math.h"

I am writing a spell checker for a exercise for a class I am taking online. I have to load a huge text file of 143092 words into a hash table.
The program segfaults on word number 63197. Is there a way to debug this in gdb without having to step threw the function 63197 times.

I am writing a C++ program which takes date & time input from the user. This is then parsed into a struct such as:
struct time
{
short year;
short month;
short day;
short hour;
short min;
};
My question is: how can I convert such a struct into a time_t object, which is an unsigned long giving the time as the number of seconds elapsed since the epoch Jan 1st 1970, 00:00, as set out in time.h.
I am wondering if this can be achieved using the standard library, or whether I just need to write a function to perform the appropriate arithmetic.

I'm trying to create a program that takes an integer input and displays each digit on a new line from right to left.
An example of this would be:
Enter an integer: 657
Digit (1): 7
Digit (2): 5
Digit (3): 6
So far I have this:
#include <stdio.h>
#include <math.h>
int main() {
int i, input, output;
printf("Enter an integer: ");
scanf("%d", &input);
if(input == 0)
printf("Digit (1): 0");
[Code] ....
It works perfectly fine, but I just learned that I am not allowed to use the #include <math.h> so I have to take out floor, log, and pow.
I'm pretty sure I have to do some sort of while or for loop to get the results, but how to do it.

i want to use a class to print data stored as vector or array with different data types. i also want the print function two take more than one vector or array or combination of both so that they can be written to file as two columns. so i wrote the following class:
right now it has only one member function for printing two vectors. later i'll add additional functions as required.
note: there has to be template functions inside the class
i also want the object to be global so that i need not pass it as an argument to other calling functions
class printdata
{
public:
template<typename T1,typename T2>
void SaveData( vector<T1> &data1,vector<T2> &data2, std::string var)
{
[Code]....
then i want to call this template function in another ordinary function written in a seperate cpp file
these function declarations are put in a header file. so i need know whether i should put the declaration of the template function in the header to use the function in different functions

I have program that is supposed to read in a story from an input file and separate the words and output the lines on which the word occurs. It needs to read in another input file that has a list of words (1 per line) to ignore. i.e. skip them when running through the story. This is what I have so far, I've changed multiple things trying to get it running....
#include<iostream>
#include<fstream>
#include<map>

I will post the entire code at the bottom. Its running fine right now but This part in the menu function I need to make as a separate function. My problem is when I make it into a function by itself I have to declare and initialize the grades A,B,C,D,F how can I do that when I can't make them equal 0 because it has to keep track of how many of each letter grade.
Code:
//Count letter grade
if(ave >= 90)
++A;
else if (ave >= 80)
++B;
else if (ave >= 70)
++C;
else if (ave >= 60)
++D;
}

How to get my data from the file and output, but now I am having trouble with my acceleration function. Right now, I have the acceleration function commented out and the output for acceleration at the bottom because if I try to run the program with them in it the program stops working. working with acceleration calculations and then finally outputting that acceleration.
//Program that reads the time and vertical velocity data and then calculates things from it
#include <iostream>
#include <cstdlib>
#include <vector>
#include <fstream>
#include <iomanip>
using namespace std;
bool calculateAccelerationArray (vector<double> t_array, vector<double> v_array, vector<double>

The file I'm reading from rocketVelocityData.txt gives me the time and velocity.

How to use a function twice to calculate two different variables. How to have a function compute the city tax, then it uses the function a second time to compute the county tax.
My program compiles, and runs fine, however it only outputs the city tax calculation. It seems it never attempts to calculate the county tax.
One thing: All of the directives I used is what we are limited to, no more, no less. He requires a set format and will dock points of you use anything but those directives and void main().
Here is my code so far:
/* function for city tax calculation */
#include <iostream>
using namespace std;
#include <string>
#include <cstdlib>
#include <cmath>
#include <iomanip>
const double city_tax_rate=0.03;

Write a c function which takes a string(as a character array, null terminated) and reverses it. it doesn't print the reversed string -- it modifies the given string so that it is reversed.
Code:
void reverse(char array[]) {
char tmp;
int i, j;
for(i=0;i<strlen(array); i++){
for(j=strlen(array)-1;j>=0;j--) {
tmp = array[i];
array[i] = array[j];
array[j] = tmp;
} } }
how come this doesn't work?

//headerfile NumArrSpecs.h
#ifndef NUMARR_H
#define NUMARR_H

My problem is that the storeElems member function is causing an error saying it is undefined, however there are no errors any where else in the program being reported. I have made several programs involving classes now, all with this three file format and this is the first time that a member function in the main file is being reported as undefined, so I'm not sure what to do.
