C++ :: How To Store Class Info Entered By User Into Array
May 7, 2013So I have an array of my own class, "Restaurant," but I'm having a hard time figuring out how to store the info entered by the user into the array.
In total, I have two classes. I will show you all I have, it's a lot but I know it will be easier to understand.
My problem is in the AddRestaurant(), since that is where I should ask the user for all the information and store it in the array.
Also consider that I have to use the FTime class as well to handle the time. Basically I want to do something like this:
info[count].SetRating();
which will put the rating part of the class Restaurant into the array[count]
Also, my program doesn't compile because of the AddRestaurant and PrintAll functions since what I am showing is what I want to do, not what works.
//main.cpp
#include <iostream>
#include <iomanip>
#include <string>
#include "Restaurant.h"
#include "FTime.h"
int ReadMenuChoice();

C/C++ :: Find Max Number Entered By User And Terminate When Negative Number Entered
Jul 15, 2014I am trying to find the max number entered by the user, and it should terminate when a negative number is entered. For my code, it will just end when the user inputs a lower number than the previous. i.e.- 10 20 15 "The highest number is 20" when it should be "10 20 5 40 15 -1" "The highest number is 40". No arrays or do/while loops either.

Visual C++ :: Create A File That Ask The User To Enter His Info
Nov 9, 2014What I want to do is create a file that will ask the user to enter his info,n then store it in a text file The screen will ask the user if he wants to update his info. if he says yes then the screen will be cleared and the old info will be printed on the screen. The user will enter his new info that will be stored in a new file. My problem is that once the user finishes entering his input the program just closes D: and the rest of the program won't run.
Code:
int main()
{
string ans;
ofstream Xfile("original.txt");
cout <<"Enter your name and address please"<<endl;
cout<<"Press Ctrl+Z+Enter when you are done"<<endl;
string name_and_street;

C :: Checking What User Has Entered (City)
Mar 9, 2013I am using Dev C++ on a windows computer.

I can't find a way of figuring out and checking which city the user has entered so the code can displays its appropriate latitude and longitude.
C++ :: How To Use A User Entered File In Fstream
Feb 14, 2014So, I am making a name-database-type-thing and I want the user to be able to enter there own file. Like, here:
string fileName;
string name;
cout<<"What is your file name?"<<endl;
getline(cin, fileName);
ifstream nameFile(fileName);
getline(cin, name);
nameFile<<"Name: "<<endl;
Well, that last part is in a loop, so you can enter an unlimited number of names to the .txt file.
So, it won't let me use the string in ifstream. How can I fix this? This maybe unclear, so if it is just say so and I will edit it.
C++ :: How To Collect Input That Has Been Entered By User
Mar 19, 2013I am making a program that will suggest meal options when choosing specifics contained within, e.g. style, base, main, sauce.
What I would like to know is how to collect the input that has been entered by the user, say you are given 4 lists and each has an option, how could I chain these together in order to cout a suggestion that is in my database?
-------------------------------------------------------------------------------
Example (not my real Q's and A's):
OUTPUT: What meat would you like?
INPUT: "Beef" //<collect this!
OUTPUT: What sauce would you like?
INPUT: "Tomato" //<and this!
OUTPUT: What would you like to have as the main/base?
INPUT: "Pasta" //<and this!
OUTPUT: I can suggest... "Spaghetti Bolognese" //< and return this from the database using the 3 filters

C++ :: How To Recognize Two Words Entered By User For A String
Feb 11, 2013In my little experiment i am trying to get the compiler to recognize 1 word with 2 parts from a list of names.
For example: if the user wanted to choose "candy bar", from a list of items which include: "candy bar", "cat", "dog"
My current code can recognize words without a space like cat and dog. But how can i recognize candy bar?
I tried using getline but its of no use.
C/C++ :: Creating Constant At Runtime With User Entered Value?
Aug 14, 2014At the moment I am making program that will use a 2d selection of "cells" to make a "map" of sorts. However, the size will not be known until run time.
I figured using an array would good, because once the size is chosen it won't be changed. However I can't create an array without using a constant.
So the first question is, can I create a constant at run-time with a user entered value that can then be used for an array size? If so, how?
Otherwise, what are my options to achieve this? I know vectors can be used, but A, my compiler keeps giving me problems even when C&P some code bits (yes I even remembered to #include and such) and B, I noticed that vectors reserve extra memory for when the size changes but this is bad (well my dinky little program won't notice, but trying to set good habits as I learn, so I'm keeping it in mind) as I don't need and don't want to allow the size to change after creation.
Which leads to number three, if I do have to use vectors, how can I prevent any accidental size changes after the initial size is determined?
C/C++ :: Finding Sum Of Values Entered By User In While-loop?
Aug 26, 2014Keep track of the sum of values entered (as well as the smallest and the largest) and the number of values entered. When the loop ends, print the smallest, the largest, the number of values,and the sum of values. Note that to keep the sum, you have to decide on a unit to use for that sum; use cm.

C++ :: Logic Error - Maze Not Displaying
Jan 24, 2014So I have a program where I solve a maze using stacks. So my display_maze function take two parameters and displays the maze according to where the x coordinate and y coordinate are.
I have an error during my move function, as my maze doesn't display for some reason
void Player::player_move() {
Stack stack;
Maze maze;
Lock taken;
// Monster monster;
stack.push_values();

It should be displaying, because after debugging I discovered the problem isn't with the display_maze function.
C++ :: Get User Input Displaying Default Value
Apr 5, 2013I would like to get user input of some parameters value (mostly of type "double", but few of type "int") but displaying the default value at the place of input. If the user does not want to modify the value, he types "Enter" to pass; if the use wants to modify the value, he enters a new value at the place of the value by default, then types "Enter" to pass to the next parameter.
Here is a simplified example:
int main() {
double a = 1.5;
double b = 2.5;
double c = 3.5;
double x;
[code]...
However, this does not work. getline() cannot take double type, and I do not know whether the rest of the code is good and efficient.
