C++ :: Create Simple Input Interface On Console - Allow To Input Values To Variables
Apr 6, 2013
I 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.

Convert this code into one where you can input the file directory from the console?
#define WIN32_LEAN_AND_MEAN // prevent windows.h from including "kitchen sink"
#include <windows.h>
#include <iostream>
#include <string>
using namespace std;
int main()
{LPCSTR Application = "C:Program FilesWindows Media Playerwmplayer.exe";
// Media file extension must be provided
// Paths are quoted
[Code] ....
This code works but the directory can only be changed from the code not the console.

Alright, so to better myself with network logic I've decided to make a small net game.
I need to input commands to the console as well as output status updates at the same time. I'd prefer to write a gui interface for that, but I'd rather work with WinAPI as little as possible (I mean, look at the way it's designed...).
I'd like to do this with standard operations, limiting dependencies is a must for me.

Console.WriteLine(" choose how many numbers ");
int i = int.Parse(Console.ReadLine());
Random randomizer = new Random();
for(int j = 0; j < 7; j++) {

I am learning c because I want to get back into programming microcontrollers, which I previously did in assembly. I wanted to make something fairly tight in terms of program memory and RAM to show me an output in binary form. When you are troubleshooting a file register or serial interface when you can see the actual bit values (on a small LCD for a micro-controller) and compare it to a datasheet.
Code:
#include <stdio.h>
#include <math.h>
int main() {
int i;
int decimaltoconvert;
int convertingarray[7];
int convertingarray2[7];
[Code] .....
Also, how might I go about putting that into a function that I could call?

I want some people to see my C++ program, enter inputs (they can enter number 1, 2, 3, etc) as CIN, and then the program runs as it would if they were sitting in my place.
I have seen a few places which try to do this e.g.
[URL]
The problem is the CIN is not fully featured. For example in the first website you have to enter the input before you run the program. So that would not work for a program where CIN was being done all the time.
So I can get a domain, ask them to telnet into the Linux shell and compile and run my c++ Demo program. Is that the best way? Thats the worst case. I send them the .cpp file and they'll have to run and compile it on their own machine.
The best case is that they click on a link, get an online console and interact with it like they would with a real input/output c++ interface.how this can be done?

I am working on a simple calculator in C++ .... All works fine with the calculator up until the requirement for the user to input "do you want to go again y/n" .... What i want to happen is the screen to clear down and reloop to the enter name part....but i can't get it to do that
Program Description: To write and develop a programme where a user can input a cost or price of something before VAT our program must then process the input number and must output the price with the original value plus VAT
#include <iostream>// I must use this to start my programming
#include <string> // I have added this for the extension task so the user has to input their name
#include <iomanip> // this is to manipulate the text
#include <stdlib.h>
using namespace std; // using the "using namespace std" shows that i will be using standard text throughout this programme

I have a simple input output problem using float point numbers and after the first input the program skips the other cin functions is there something that I did wrong? It compiles fine also.
Code:
#include <iostream>
#include <float.h>
using namespace std;
int main() {
int x;
int y;
int z;

Making a game of checkers on C++ win32, visual studio
when i want a piece to move, i type:
cout << "What piece do you want to move? (C4)" << endl;
i type in 'cin' after to get the players input, but how do i get it to store the players input in a certain variable? im going to have a list of variables:
string a1
string a2
string a3
etc
so if the user types in a2, it automatically goes to that variable and then asks the user "where do you want the piece to be moved to?".

Using cin.sync() works great so far, but my program still breaks if you copy something with multiple lines into the console.
string test = "";
while(true) {
cin.sync();
getline(cin, test );
cout << endl << "test: " << test << endl;
}
However, if you were to copy this:
1
2
3
and paste it into the program, the output would be1
2
3
test: 1
test: 2
And if you press enter one more time:1
2
3
test: 1
test: 2
test: 3
The 3 finally pops out.

I just started programming and want to make the game cows and bulls. The problem is that after the loop has ended and both vectors are not the same I want the user to 're-input' the starting variables a,b,c&d but I don't know how to.
Code:
#include "std_lib_facilities.h"
int comparison(int a, int b, int c, int d)
{
vector<int>bc={ 1, 2, 4, 9 };

I need to create a C Wrapper around a C++_Class and in between needs to be an Interface-Class. The Interface-Class is needed, cause there are more C++_Classes which are kinda equal.
Hierarchicaly it would somehow look like this:
=> XY-Process which is calling the CWrapper
==> CMeasureWrapper.c// <-- CWrapper
===> CMeasureWrapper.h// <-- CWrapper Header
====> IMeasurement.h// <-- Interface-Class
=====> CMeasure.cpp// <-- C++_Class
======> CMeasure.h// <-- C++_Class-Header
My Output after compiling.(files will follow)
// CMeasureWrapper.c | CWrapper
#include "CMeasureWrapper.h"
uint32_t gu32_objectHandle;
uint32_t gu32_measureType;
int32_t addNewMeasureObject(uint32_t u32_measureObjType)
{
int32_t t_status = 0;
[Code]...
It's the first time i'll try to build an CWrapper or even a wrapper. So maybe the Project-Properties need to fit as well.
The project itself is called "Platform" with following settings in:
C/C++ -> Advanced -> Compile As -> "Compile as C++ Code (/TP)"
This property on the CMeasureWrapper.c is switched to:
C/C++ -> Advanced -> Compile As -> "Compile as C Code (/TC)" but only on this file!
I'm not sure if it's necessary, the file is of .c type, so I wasn't sure.
what I am doin wrong? Not just depending on the error output, I mean on the whole project. Is there anything else which will not work with such a combination of CWrapper, Interface and C++_Classes? If there are any questions, just throw them at me

I am trying to create a five second timer that allows a value to be entered in that span of time. However, if a value is not entered within the five seconds, the timer ends and a value will no longer be able to be entered. I am trying to create a math test that has a five second time limit for equations to be answered.

I want to create three files whose names are same but extensions are different. I have to take the name from user. I tried following code but it didn't worked ...
Code:
printf("Name of the file:"); scanf("%s",name);
printf("Format of Input file:");
scanf("%s",ext);
f1=fopen(name.ext,"r");
f2=fopen(name.dat,"w");
f3=fopen(name.src,"w");
f4=fopen(name.RMH,"w");

I would like to create a C program which requires the input in this form: number1 operator number2, where number1 and number2 are numbers of type double and operator is one of the characters +,-,*,/.
There is my attempt to write this code:
Code:
#include <stdio.h>
double main() {
char operator;
[Code]....
Now I have to solve these problems: This code above doesn't work and I don't know why.I don't know how to fix the case when some user enters the input in this form:
Code: 1.5896 *5 or
Code: 7 / 5
I mean how the program knows that
Code: 1.5896 *5 is the same as
Code: 1.5896*5
I don't know how to fix the case when the user enters the input in the incorrect form for example
Code: 3

I 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".

I 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 ....

Same 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);
[Code]....

What "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);
[Code]...
