C++ :: Program To Order Pizza - Empty Controlled Statement Found Error
Aug 25, 2013
I am creating a pizza program for ordering a pizza and I have removed all the errors except for two. I have tried everything I can think of to fix this problem so it will compile, but to no avail. The only errors left are:
1>------ Rebuild All started: Project: Pizza Order App Midterm, Configuration: Debug Win32 ------
1> stdafx.cpp
1> Pizza Order Midterm.cpp
1> Pizza Order App Midterm.cpp
1>c:usersindia-n-jerrydocumentsvisual studio 2010projectspizza order app midtermpizza order app midtermpizza order app midterm.cpp(57): warning C4390: ';' : empty controlled statement found; is this the intent?

The entire code is listed below seperated into 1 header and 2 cpp files.
// OrderPizzaApp.cpp : Defines the entry point for the console application.//
I think my linker needs an additional #include to be able to deal with int& anterior and int& posterior. I'm not sure as I'm new to C++. My version of Dev-C++ is Orwell V5.8.3.
"fatal error LNK1169: one or more multiply defined symbols found"
Here's my code:
#include "stdafx.h" #include <iostream> using namespace std; int main () { cout << "Avoiding Technology" << endl; bool status = true; int location; int a,b;
I am debugging a library. I can step into the code however the watch window doesn't show the values of any variables. It will display a message in the value field:
Code: m_pParentCXX0017: Error: symbol "m_pParent" not found
Interestingly it does show values for local variables in that function but not member functions. Most of my data members are member function though that I want to debug. I am using VS2010.
This feels to me like a relatively "deep" C syntax question. Reviewing K&R reveals some interesting, related specifications, but I could not nail this down. The issue is, What determines the order in which expressions are evaluated in an if() statement? Now, K&R gives details with regard to the precedence of operator evaluation, but otherwise I could find only 2 sections detailing the order of expression evaluation (I mention these below). A simple code example demonstrates why this is a burning question to me:
So what if pi is passed in NULL? Is it possible for the *pi expression to be evaluated Before the (NULL != pi) expression? If so, you could have an access fault. If not, what rule of C ensures left-to-right evaluation? Is this a simple case of the left-to-right associativity that K&R shows on page 49 (in the table of operator precedence) for the && operator? Or is there some more general rule that applies?
The two mentions in K&R I did find are that function argument evaluation order is Not defined (pg 86). Also, beyond the order specified in the reference section for operators, they state there is no other defined order. In particular, they state:
"Expressions involving a commutative and associative operator (*, +, &, |, ^) may be rearranged arbitrarily, even in the presence of parentheses; "
That surprised me! I suppose the point is that compiler-made changes in this case cannot change the result. I wonder whether this or other similar rules in C were superseded in C++ ?
In a similar vein, what about the expression evaluation order for the for(,,) statement - does it have guaranteed left-to-right order?
#include <stdio.h> /* function that will identify if line is empty or not */ is_empty(char *buffer) { while(isspace(*buffer)) buffer++; if(*buffer==0x00) return 1;
I'm trying to make a simple C++ program in which the user must try to guess a number, if they guess too high it says "too high" and if they guess too low it says "too low".
I also decided to add a feature which allows them to select how many tries they would like to guess the number. I tried to make "tries" type an enum so if the user could not pick an invalid number but for some reason i cannot use it in an if statement.
here is the code and i am getting the first error on line 27:
Code: #include <iostream> #include <ctime> #include <cstdlib> using namespace std; int guess;
Code: /* Demonstrates using the gets() return value. */ #include <stdio.h> /* Declare a character array to hold input, and a pointer. */ char input[257], *ptr;
[Code]....
I just got this from the book that I am using and it is for testing for input of a blank line and readers are being warned in using this format (line 18):
Code: while ( (*ptr = gets(input)) != NULL)
What is the correct syntax if a gcc compiler is to be used?
I have a question related to switch statement, which the switch in class employee2 gives me error at output. Program compiled well. I am using Code::Block Compiler V10.5. I have created object of class employee2 in main() function to get data from user, store it and display it. At the output, Compiler doesn't show actual output what i am expecting. The fun thing is my compiler printed emocion like (), where (hourly/monthly/weekly) was supposed to print.
Code: #include <iostream> using namespace std; enum period {hourly,weekly,monthly}; class employee2 { private : char ch; period x; double compensation;
I have written a program that stores employees in a database object. You can Add, hire, fire, promote, demote, and display employees. The program uses an interface, a database class, and an employee class with member functions.
The strange behavior is in my switch statement in interface.cpp. I have a '#' that represents a command line. Add and Display functions are ok, but if I hire, fire, promote or demote. It will display '##' for the next input. I ran the debugger and after hire/fire/promote/demote is called, the first if-statement goes to 'else' and I'm trying to figure out why.
if (comboBox1.Enabled == true && textBox5.Text != "") { OleDbConnection con = new OleDbConnection(); con.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;" + @"Data Source= c:usersmert" + @"documentsvisual studio 2010ProjectsPayrollCSWindowsFormsApplication7P ayrollDB.accdb";

this is my code. I am getting this error on "cmdole2" query.
error text is:
---------------------------
--------------------------- System.Data.OleDb.OleDbException (0x80040E14): Syntax error in INSERT INTO statement. at System.Data.OleDb.OleDbCommand.ExecuteCommandTextE rrorHandling(OleDbHResult hr) at System.Data.OleDb.OleDbCommand.ExecuteCommandTextF orSingleResult(tagDBPARAMS dbParams, Object& executeResult)
The program should be print the numbers 0 through 10, along with their values doubled and tripled. The data file contains the necessary variable declarations and output statements.
Example the output:
Single Double Triple 1 2 3 2 4 6 3 6 9 4 8 12
here my code tell me if correct
#include <iostream> #include <cstdlib> using namespace std; int main () { int x, double, triple;
I've encountered a slight logical error in my code
/* Lab06_pensionplans.cpp Purpose : - Create a simple financial application to calculate retirement plans */ #include <iostream> #include <cstdlib> using namespace std; void displayMenu() { system("cls");

Look at case 2, which the user supposed to key in a new input, the problem is the value will never got into main function, I don't know what should I modify with the function.
I can't seem to figure out whats causing this error: statement cannot resolve address of overloaded function . Error is before line 14 in bubblesortrand function. Thnx in advance.
void bubblesort(int num[], int a_size) { int i, j, temp; for(i = (a_size - 1); i >= 0; i--)
I'm working on a personal project with a screen that looks like this:
+++++ +++++ ++O++ +++++ +++++
And below that it asks where you want to move. I've done the majority of the work, I just have to figure out how to actually move the O. Here's my source code:
#include <iostream> #include <iomanip> #include <algorithm> using namespace std;
need to create a program for the following problem
1.Program takes messages as input at a rate “X” msg/sec, and outputs those messages at “Y” mgs/sec in a file.
2.The peak value of X can be 10msg/sec, and Y can be at max 5msg/sec. System should be designed in such a way that it can handle the peak input rate of 10msg/sec for not beyond 5 minutes.
3.Message contains following fields – unit id, timestamp, temperature.
4.Input data to be read from a file. Output data to be written to a file.
5.For testing design 3 types of profiles –
a.Profile 1 for 10 min – low rate, i.e. X = 4 msg/sec on an average throughout the period. b.Profile 2 for 10 min – Max rate, i.e. X = 10 msg/sec for 2 min; then a sleep of 2 min, then repeat the same pattern till complete period c.Profile 3 for 10 min - Max rate, i.e. X = 10 msg/sec for 5 min; then no traffic for next 5 min
Write a count controlled loop than can print "i" char. The user is supposed to input a integer and that integer is how many asterisks there is on the blade, in this case it is 5.
* * ** ** **--------------- ******* ** ** ** * ** * -10 Rows high ** -blade always connects on second row of handle ** ** ** **------------------
I have an if statement that should either match a text variable that the user has entered and a another text variable that has been got from an array but they won't match even if they are the same,Im at a lost with it.
Is it possible to create a program like Robocode, a game controlled at runtime by an external source file in visual c ++? For example create a checkers game where there would be an external source file, read at runtime, which would play automatically, with artificial intelligence. You can? If yes, how?
