I've just recently started to learn C++, and I'm encountering some errors I can't seem to figure out.
InventoryItem.h:
Code: #pragma once class InventoryItem { public: InventoryItem(string name, int amount); ~InventoryItem(void); string getName(void); int getAmount(void);
I am just starting out with loops and I have run into an syntax error and for the life of me I cant find out the issue. Before it has been an issue of me forgetting to close my brackets but I am pretty sure I did that this time. I am trying to have the program keep looping the main menu until the user inputs a correct number.
I keep getting a "Declaration syntax error" at line ""int main()". Is there something wrong with my int main()? And how do I go about it? Here is the program:
#include<stdlib.h> #include<iostream.h> #include<stdio.h> #include<math.h> #include<conio.h> float rung4(float x, float y, float h) int main() { float eps=0.00001;
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";
[Code]....
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)
My compiler (GCC) keeps expecting an expression where it shouldn't in 1 specific piece of my code:
int zxcNewWindow( HWND parent, TCHAR *text, zxWINDOW *kid, UINT style, int x, int y, int w, int h, int type ) // right here { *kid = zxDefWINDOW;
The project contains only 2 files right now and the settings are just the default for an empty Code::Blocks 12.11 project. Both files are in UTF-8 format (tried in ASCII too), I just cannot see why this is not compiling correctly. I'll post the files in the next two posts.
Edit: For those of you who didn't get what the error was from the above here's the full log:
mingw32-gcc.exe -Wall -g -DzxDEBUG -c C:MePrjscppzxGUImain.c -o objmain.o C:MePrjscppzxGUImain.c: In function 'zxcNewWindow': C:MePrjscppzxGUImain.c:39:10: error: expected expression before '{' token Process terminated with status 1 (0 minutes, 0 seconds) 1 errors, 0 warnings (0 minutes, 0 seconds)
I am trying to run this source code but i am getting the compiler error Expression Must Have a Constant Value. I tried making both the variables x and y constants and assigned them to a significantly big number but then i am getting the error expression must be a modifiable lvalue.I have made comments in the code in front where Visual Studio is giving me the syntax error (red squiggly line).
#include<iostream> #include <string> #include<cmath> using namespace std; int main(){ int x; int y;
#include <iostream> #include <iomanip> using namespace std; //chose to use #define since columns/rows are a constant in the program #define x 5 #define y 3 int main() { //declare variables
I'm trying to learn recursion, and I'm using a simple array to experiment with it, but I have a couple of annoying errors that I don't understand why they're there. Here's the code:
Code: #include <cstdlib> #include <iostream> using namespace std; int largest(const int arr[], int lowerIndex, int upperIndex) { int max;
[code]....
Now try to print the array backwards:
//Use a recursive algorithm to find the largest element in arr: int largest(arr[], lowerIndex, upperIndex);//error: expected an expression return 0; }
Code: void change(pixel_t *pixel, int w, int h, pixel_t *buffer) {
int average, sum; int i; pixel_t *pointer;
Everything else works fine. I keep getting an error when I call the convert function. It says "expected expression before pixel_t" and "too few arguments to function "change". I know that everything else in the main is working.
class Secure { private: int seconds; bool isRUNNING; public: Secure(int seconds) {

I read that due to explicit casting, threads cannot be created within a class. I'm trying to thread a scanning system to relieve stress on my main program/module, rather than having the scanner stunt their performance.
Q. In context of C language syntax checking, which of the following can be modeled using Finite Automata?
(A) Detecting proper termination of an instruction. (B) Detecting balance of parentheses. (C) Detecting initialization of a variable. (D) None of the above.
I'm familiar with function pointers as the method to pass a function as an argument to another function. However, I recently encountered some other syntax. I have seen in multiple times and in books,so I know it is probably not a syntax error. But I am not totally sure.
#include <iostream> void Function1() { std::cout << "Function1"; } void Function2(void aFunction()) { aFunction(); } // make a param that describes the function the will be given // as a param (return type, identifier,
I had to learn how to use variadic templates recently, and had trouble finding simple examples that just showed the basic syntax.
So I decided to write one myself. Admittedly, it's a bit on the long side, but that is mostly because it includes five specializations.
insert Code: // Variadic.C // Compile command: g++ Variadic.C -std=c++0x // I used GCC version 4.6.3 on Ubuntu.
// This file contains a basic variadic template with five specializations. // It is intended for non-software engineers who are looking for a simple // example of variadic template syntax.
