C++ :: Unexpected Expression Compiler Error

Jul 30, 2013

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)

C++ :: Compiler Error - Expression Must Have A Constant Value

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;

C++ :: Compiler Error C2664 And C2228

Nov 9, 2013

Working on a basic class program and I'm generating two compiler errors that I'm not sure how to fix. Header file, implementation cpp and main cpp are shown below. The specific errors are shown after the code.

Header file Code:

#include <iostream>
#include <string>
#include <cstdlib>
#include <iomanip>
using namespace std;

[Code].......

The file generates the second error, C2228, at lines 37-41 and 43. Basically where I tried using the second created object. Error message is "left of '.setFirstName' must have class/struct/union"

C++ :: Compiler Error C2370 And C2011

Nov 29, 2013

Working on a solution involving inheritance. The whole solution is pretty massive at this point so I'll just focus on the problem areas. I'm getting a lot of "redefinition" and "undefined class type" compiler errors, including C2370, 2011, 2504, and 2027, in Benefit.h, Employee.h (the constant members are a big occurance) I'm also getting 2027 and 2079 in EmployeeMain.cpp. with my Benefit and Employee object calls.

Clearly I missed something in about how to code this correctly. Sadly the course textbook focuses on general OOP theory instead on the accompanying C++ syntax.

Benefit.h
Code:
#include <iostream>
#include <string>
#include <cstdlib>
#include <iomanip>
using namespace std;

C++ :: Error / Expression Must Have A Class Type

Apr 15, 2015

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;
}

C++ :: Simple Class Usage Compiler Error

May 12, 2013

Full disclosure: this is an exercise from "Sams Teach Yourself C++ in 24 Hours" by Jesse Liberty and Rogers Candenhead. This refers to Chapter 9 (Hour 9 Activity 1)

I created a class called Point, in Point.h

I created a class called Rectangle in Rectangle.h and Rectangle.cpp

If I create an int main() function in Rectangle.cpp (that includes Rectangle.h), I can compile Rectangle.cpp and run the resulting program. Fine.

Question:

I create a separate file called main.cpp. I include Rectangle.h. But now the compiler complains.

Code:
$ g++ main.cpp -o main
/tmp/cc38JIph.o: In function `main':
main.cpp:(.text+0x26): undefined reference to `Rectangle::Rectangle(int, int, int, int)'
main.cpp:(.text+0x32): undefined reference to `Rectangle::getArea() const'
collect2: ld returned 1 exit status If I can create a class in Point.h and use it in Rectangle.h, why can I not just use Rectangle in main.cpp?

And the files, of course:

file: main.cpp
Code:
#include <iostream>
#include "Rectangle.h"
using std::cout;
using std::endl;

[Code] .....

C++ :: Compiler Error C2374 - Multiple Initialization

Nov 1, 2013

Well, I thought I had this program working but now I'm getting the above referenced compiler error. The program is just a basic user interface. It is for a classwork assignment.

The program is to accept user information as a string, convert it (if needed) to either the int or double variable, and then display the result. I'm using stringstream convert to make the change between types, but I'm not sure if I'm using it right (that might be what's causing the error, I'm not sure). Line 36-37 generates the error.

Code:
#include <iostream>
#include <iomanip>
#include <sstream>
using namespace std;

C++ :: Shape Class Polymorphism Compiler Error

Dec 10, 2014

Having issues with program to create a shape area calculator with circle square and rectangle. the uml goes as follows:

Where the UML has shape as the abstract class with public area():double, getName():string,and getDimensions:string, rectangle derived from shape with protected height, and width, and a public rectangle(h:double, w:double), followed by a derived square from rectangle with just a public square(h:double), and finally a circle derived from shape with a private radius, and a public circle(r:double).

[URL]

Have linked my program and it is giving me the following compiler errors:

error: 'qdebug' was not declared in this scope line 15 of main

error: cannot declare variable 'shp' to be of abstract type 'shape' line 22 of main

error: expected primary-expression before ')' token lines 29 -31 of main

(note previously had qstring as a header file yet changed to string since I was getting error qstring was not declared in this scope.)

C/C++ :: GCC Compiler Does Not Detect Multiple Definition Error

Oct 31, 2012

I am trying to compile the files file1.c and file2.c using Mingw (gcc)

/////////////////////
header.h
////////////////////
#ifndef header
#define header  
int variable;  
#endif

[Code] ....

I would have expected a multiple defnition error when linking the two .c files. as in both the files, with the 'int variable' command, the variable 'variable' is defined (memory allocated) and during linking the linker doesnot know which variable to link to.

I get an error though when i use "int variable =123;" in the header file instead of the "int variable;" statement. i dont understand as in both the cases the variable is defined (memory is allocated) and the linker should give a multiple definition error.

Visual C++ :: Compiler Error With Cout Object

Dec 15, 2012

I am asp.net C# developer. I decided to tackle C++, so I started today. This is probably something simple I am sure.

Code:
srand(static_cast<unsigned int>(time(0)));
int choice = rand() % NUM_WORDS;
string theWord = WORDS[choice][WORD];
string theHint = WORDS[choice][HINT];

[Code] ....

The error is happening on the last output operator, just before the jumble variable on the last line.The error is:

Code:
Intellisense: no operator"<<" matches these operands

operand types are: std::basic_ostream<char, std::char_traits<char> <<std::string

I understand what its saying, but jumble is a std::string

Here are my preprocessor directives and using statements

Code:
#include "stdafx.h"
#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;

C :: Stack Overflow - Expected Expression Error

Sep 10, 2013

I'm pretty new to C, and keep getting an error. Basically I'm trying to convert a ppm image to all red. Here is my code that I can't get to work:

Code:
change(pixel_t *PIXEL, &w, &h,pixel_t *buffer);

And here is the beginning of my convert function:

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.

C++ :: Implementing Hash Table - STL List Compiler Error

Jun 5, 2013

I have been implementing a Hash Table class made, and ran into a bit of a problem in my Delete function. I have the hash table made up as

vector<list<HashNode<T,X>>> m_Table

My problem is when I iterate through the vector, and then the list in that current element to try and find the Node I want to delete, the STL list class gives me the error:

Error1error C2678: binary '==' : no operator found which takes a left-hand operand of type 'HashNode<T,X>' (or there is no acceptable conversion)

Here's the Delete function:

template <typename T, typename X>
void HashTable<T,X>::Delete(T key) {
HashNode<T,X> Node;
HashNode<T,X> NodeTemp;
list<HashNode<T,X>> temp;
list<HashNode<T,X>>::iterator it;
vector<list<HashNode<T,X>>>::iterator iter;

[Code] ....

Why it's not letting me do the .Remove() function?

C++ :: Unexpected Output In Example Function

Jan 21, 2015

I am currently trying to understand why this example for using an array as an argument in a function has a different result than what the lecture notes say it should be.

So supposedly sum should return with the value 28, but I get 27 no matter what. I also am not very good at reading and understanding what exactly the order of operations for this function are.

Code:
#include <iostream>
using namespace std;

int sum(const int array[], const int length) {
long sum = 0;
for (int i = 0; i < length; sum += array[++i]);
return sum;
