C++ :: Create Simple Input Interface On Console - Allow To Input Values To Variables
Apr 6, 2013I am trying to create a simple interface on console to allow to input some values to some variables. For ex:
int main() {
double a = 1.5;
double b = 2.5;
double c = 3.5;
string x;
[Code] ....
However, I want these three to display at the same time (now they display one by one), and in the console window I can move the cursor between input place of a, b and c with "arrow key" of keyboard.
C++ :: Print Out All Input Values
Mar 16, 2013I have a problem with how to print out all the numbers that the user enters the code looks like this so far:
Code:
#include <iostream>
using namespace std;
int main()
[Code] ....
I want the program to print out all the numbers that the user has entered after the program have said the higest and lowest number is ?. But I do not know how to do this I thought it could be something like this:
Code:
cout << input[0];
//or
cout << input[i];
/*
Because i is the number of how many enters of numbers the user can do*/ But that was totally wrong tried to do another "for loop" in the first for loop but that was meaningless because it can't change anything in the first "for loop".
C/C++ :: Calculate Sum For Input Values Of X And N
Feb 27, 2015I added my assignment to attachment, i need to calculate the sum for input values of x and n this is my code:
#include<stdio.h>
#include<math.h>
main() {
float gore,dole,s,x;
int n,i,j,z;
s=0;
i=0;
j=0;
[Code] ....
gore calculates x^(2*i)-3 and dole is for (2+i)! for input x=1 and n=1 i get -2.0 output which is the value of x^(2*i)-3 the (2+i)! part gets ignored for some reason, for any other input i tried the output is 0 ....
C++ :: Input Showing As Default Values?
Nov 30, 2013Same solution that I was having compiler errors on yesterday. We're working with inheritance and the program is supposed to be to create and display information for default Employee objects, Hourly Employee objects and Salaried Employee objects. Everything compiles as is, but I'm running into two issues that I can't figure out.
1) In both the hourly and salaried objects, the wage, hours, and management level attributes all displaying their default values. I'm almost positive that this has something to do with the str to int and str to double conversions that I'm using (currently have atoi and atof in the file, but I've also tried stringstream, but still had to same problem). Any thoughts as to what I'm missing?
2) the assignment calls for the Benefit benefit member in Employee.h to be protected. However this makes the member unaccessible when I try to use it in the EmployeeMain.cpp in order to set the input for the Benefit class members. I had to make the Benefit benefit member public again to get it to compile. How would I set the input for the Benefit class members while the Benefit benefit member is protected?
Solution files follow:
EmployeeMain.cpp
Code:
#include "Hourly.h"
#include "Salaried.h"
void DisplayApplicationInformation();
void DisplayDivider(string);
string GetInput(string);

C++ :: how To Input Values Into Array Via Functions
Sep 5, 2014What "int values" is supposed to mean as parameters to these functions? I'm not sure what do with them. Also how to input values into the array via functions. I was trying to but I just don't understand how to connect a user's input to a function to then enter into an array.
// input reads “values” integers from the user to place in the array data. It prompts the user for each value individually with the ordinal position of the value.
void input (int data [size], int values);
// Places the sum of corresponding values from arrays a and b and places the results in array s. The first “values” integers in the array are processed.
void do_sums (int a [size], int b [size], int s [size], int values);

C/C++ :: Matching Input Value To Values In Array
Apr 1, 2015I have developed the following code for a PIC18 micro-controller. The object of the program is to compare a input value (presumably from a magnetic swipe card), represented here as scan_id, to a list of valid access ID's represented by the array valid_id. If there is a match the program will drive an output pin high to light a green LED for 20 seconds. If there is not a match the program will drive an output pin high to light a red led for 20 seconds.
The issue that I am having is that when the program is executed, the "else" case for the red LED is always selected regardless of the value for scan_id. If I change the "if" statement from == to = then the case for the green LED is always selected regardless of the value for scan_id.
#include <p18f452.h>
#include <stdlib.h>
#include <stdio.h>
#include <delays.h>
void main () {
TRISA=0xFF; /* Configure PORTA<7:0> pins as inputs */

C# :: Accept Two Input Parameter And Returns Two Out Values
Jan 26, 2014class Program {
//Accept two input parameter and returns two out value
public static void rect(int len, int width, out int area, out int perimeter) {
area = len * width;
perimeter = 2 * (len + width);
[Code] .....
why is the static keyword required in the method signature for the rect() method. It will not compile if it is absent. why?
the same is true for this example:
class Program {
static void printvalues(params int[] passedin) {
foreach (var printthis in passedin) {
Console.WriteLine(printthis);
[Code] ....
This code won't compile without the static keyword in the printvalues() method signature. why?
C++ :: Can't Store Different Values Into Vector By User Input
May 4, 2013I can`t seem to store multiple values into my vector when a user keys in an input. Lets say a user inputs 1,2 as the first set and later keys in 3,4.

C++ :: Unable To Extract Unsigned Values From Input Stream
Jan 16, 2015I am trying to extract unsigned values from an input stream. I expect the extraction to fail when an invalid character is extracted. It fails correctly when I try to extract an unsigned int from "abc", but when I try to extract an unsigned in from "-1", the extraction succeeds, and the max unsigned int value is extracted (as if -1 were cast to unsigned int). I would expect the '-' to cause the extraction of an unsigned value to fail.
The code I am using is below.
#include <iostream>
#include <sstream>
#include <string>
#include <limits>
int main() {
unsigned int value = 8;
std::string negString = "-1";
[Code]...
Is this standard behavior for an istream extractor?
I am trying this in both Linux (gcc 4.4.3) and in windows with Code::Blocks (whaterver came with CB 13.12, apparently gcc 4.7.1)
C++ :: Incrementing Values In Vector Based On Variable Input
Mar 24, 2014I'm trying to increment the values in a vector, not the vector size, based on variable input. Basically I have a vector of size 10, and all of its values are initialized at zero. The program counts the frequency of numbers 0-9 in a four digit user input. This is what I have (I want it to work so badly but the compiler says that I'm using a pointer to a function used in arithmetic):
for (int i=0; i < num_slots; ++i) {
++guess_frequency[guess[i]];
}
I just want to know if you can increment values within a vector:
E.g.
change
0 0 0 0 0 0 0 0 0 0
to
1 0 0 0 2 0 0 1 0 0

Visual C++ :: Program Doesn't Accept Input Values True?
Nov 1, 2014I am making a program which is going to print out a head image according to the input values entered by the user. Here is the code:
Code:
#include <iostream>
#include <string>
using namespace std;
void Sides()
// draws the sides to take proportion
[Code] .....
At first i tried to work program like:
Code:
cout << "plase enter which way you want to print out the head, with parted hair or bald." << endl;
cin >> headstyle;
if (headstyle != "bald" || headstyle != "parted hair" )
But it also had given the same mistake. The program compiles BUT; even if I put in the values bald or parted hair the program prints out "wrong input" then exits.

C :: Save Values From A Char Buffer Into Integer Values Of A Struct?
Jul 3, 2013I'm attempting to save values from a char buffer into integer values of a struct.
This is what resides in the buffer "STD 2 2 2 2 2 2 2 " and this is my sscanf call
Code:
sscanf(buffer, "STD %d %d %d %d %d %d %d
", &dt_struct.date,
&dt_struct.mth,
&dt_struct.year,
&dt_struct.dow,
&dt_struct.hr,
&dt_struct.min,
&dt_struct.sec);
I then print the values back out in a string using sprintf.
Code:
sprintf(t_string, "STD %d %d %d %d %d %d %d
", dt_struct.date,
dt_struct.mth,
dt_struct.year,
dt_struct.dow,
dt_struct.hr,
dt_struct.min,
dt_struct.sec);
But this is what I get:
STD 0 0 2 0 0 0 2
Instead of what I want:
STD 2 2 2 2 2 2 2
C++ :: Dequeuing Integer Values From Heap Results In Garbage Values
Apr 8, 2015I've been working on a homework assignment that randomly generates integers and populates them into an array (array1). The program is then supposed to:
1.) copy those values to a second empty array (array2)
2.) sort the values already in array1 (using an inline function)
3.) enqueue the unsorted integers from array2 into a heap vector
4.) a third empty array (array3) is supposed to be populated with those unsorted integers (by dequeuing them from the heap), sorted in reverse order.
But no matter what I do, I always get garbage values like these:
I've tried using both a standard random number generator:
array1[i] = rand()%100+1;
And the d_random.h file my instructor gave us, but nothing works.
Here's the code from all 3 files:
HeapTester.cpp
Code:
#include <iostream> // Provides cin, cout
#include <cstdlib> // Provides EXIT_SUCCESS, rand, srand
#include "d_random.h"//Provides random number generator
#include "Heap.h"
using namespace std; // Use C++ Standard namespace
//Elements in each array.
const int arrayLength = 15;//100;
[Code] ....
Why I'm getting those garbage values?
C# :: Making String Equal Many Different Values Then Compare Those Values

Here I would like to see if my speech had ended with any of the values i would have stored in the string "numbers". If it did, I would like to just take the value and add it to a new string called whatever

I have tried this a million different ways and I cant get it to work. I'm not even sure how I would go about storing tons of different numbers in one string, or if that's even possible.
C/C++ :: Compare Values Stored In First Array To User Inputted Values In Second Array
Oct 19, 2014Goal: Write a program that compares the values stored in the first array to the user inputted values in the second array.
In order to fix this error: [URL]...
I had to change my array initialization to one with a star in front of it:
char a1[]={"a","d","b","b","c","b","a","b","c","d","a","c","d","b","d","c","c","a","d","b"};
to:
char *a1[]={"a","d","b","b","c","b","a","b","c","d","a","c","d","b","d","c","c","a","d","b"};
I also changed my 2nd array to one with a star in front of it: char *a2[20];
What does this mean exactly? Putting a star in front of an array?
Also, I am now getting an "unhandled exception" when I try to get input for my 2nd array:
cin>>a2[i];
