have several linux header files included and when I compile my program I get the below errors..Am I NOT supposed to use some of these headers? Source is below as well.Looking through the headers mentioned in these errors, it's looking like stuff really is defined in multiple places...

I've included <cstddef> into a project of mine in favour of <stddef.h>. When I tried to compile my project, I get 50+ errors stating that types such as "::size_t", "::div_t" and "::abort( )" have not been declared even though <cstddef> includes <stddef.h>.
I've tried searching both the global namespace and the standard namespace, but neither way works. At this moment in time, I don't have any compiler options enabled that may affect the way identifiers are defined, C++11 isn't enabled (which doesn't affect the <cstddef> header anyway), the project is a C++ project, and I've tried using the plain old <stddef.h> header, but the problems still persist.
I'm using GNU's C++ compiler ("__GNUG__" is defined).
I am new to C++ language and I am still learning.I'm doing basic stuff to better understand dynamic memory. I was wondering why I keep getting memory issues.*/

At this stage I will obtain Dimensions A, B & C. But after this before I do the pythagoras equation using the data I want it checked over. I think I've done this here but I'm not sure. I want it to report the message "Invalid Data" if Dimension A is not the longest.
cout << "Enter Dimension A:-";
cin >> DimA;
cout << "Enter Dimension B:-";
cin >> DimB;
cout << "Enter Dimension C:-";
cin >> DimC;

i use cygwin and i have a program that was returning an error saying "undefined reference" and i figured out that i misspelled a word. how can i search for the misspelling in the input mode, if ive just completed a very large program and dont want to scroll through possibly 300+ lines of input? im not totally out the loop, but i know i can "vim program.cpp" to open the program, but before clicking "i" to actually edit, there must be a way to search a word

I am writing a program in C. The following is an extract from my code:
Code:
enum coin_types{
FIVE_CENTS=5,
TEN_CENTS=10,
TWENTY_CENTS=20,
FIFTY_CENTS=50,
ONE_DOLLAR=100,

[Code] .....
I'm getting the following errors:
For: new = new_coins_data_line(line);
"Incompatible types in assignment"
For: return newdata;
"Incompatible types in return"
There seem to be problems with my variables and perhaps it is related to the type 'struct coin' which has an enumerated type within it.

I've recently downloaded the original DOOM source code from id Software's GitHub page. I decided it would be fun to port it to Windows 7. I created a new Win32 application within Microsoft Visual Studio 2010 Professional, added all the DOOM files to the project, and hit compile. I got a ton of odd errors, so I switched the project from C++ to C and hit compile again. I got a few more errors, which I've mostly resolved (they come from the fact that the DOOM code I downloaded was written for Linux in 1993), and an error on nearly every symbol in cmath. The errors are C2059 and C2061. A little bit of digging around online revealed that these errors come from including cmath in a C project. However, I can find no reference to cmath in my code files.
A little more digging around online revealed that certain C++ files, like fstream, include cmath. I removed all of those that I could, but to no avail. How I can get rid of these errors?

Ive been writing this code all day and these errors have been killing.
Instructions:
Car Class:
Write a class named Car that has the following:
year. An int that holds the cars model year.
make. A string object that holds the make of car.
speed. An int that holds the cars current speed.
In addition, the class should have the following member functions.
Constructor. The constructor should accept the car's year and make as arguments and assign these values to a object's year and make member variables. The constructor should initialize the speed member variable to 0.
Accessors. Appropriate accessor functions should be created to allow values to be retrieved from an object's year, make, and speed member variables.
accelerate. the accelerate function should add 5 to the speed member variable each time it is called.
brake. The brake function should subtract 5 from the speed member variable each time it is called.
Demonstrate the class in a program that creates a Car object, and then calls accelerate function five times. After each call to the accelerate function, get the current speed of the car and display it. The, call the brake function five times. After each call to the brake function, get the current speed of the car and display it.
Errors: error C2061: syntax error : identifier 'stringm'
error C2533: 'Car::{ctor}' : constructors not allowed a return type
error C2511: 'Car::Car(int)' : overloaded member function not found in 'Car'

I'm doing a homework assignment where I have to calculate monthly interest from a starting balance. I've pulled several sections of the code from various parts of the book. So my problem may be that I'm not combining them correctly.
I'm getting the following error:
Error1error LNK2019: unresolved external symbol "public: __thiscall SavingsAccount::SavingsAccount(void)" (??0SavingsAccount@@QAE@XZ) referenced in function _main
The ios flags are new to me and that may be part of the problem. As soon as I can get a working program, I'm going to make the starting balance and interest rate user inputs. But I get seem to get past this error.

I have to find at least 5 errors in the following class template. I have found three and it now compiles, here is the template
#include <map>
#include <utility>
template <class T> class foo{
public :
foo(T bar1, T bar2){
_bar1.push_back(bar1);
_bar2.insert( std::pair<T,T>(bar1,bar2) );
[Code] ....
The errors I believe I have found are as follows: the vector library has not been added, the map requires two type arguments rather than one and the object which is created in main doesn't pass any values to the constructor. I fixed all of these errors and the code now compiles without errors, however the problem asks for five.
I've just started coding a "Mathematics" library for my own, just to practice some OOP concepts, but sadly I didn't get too far with it before the first errors appeared. That is, I created a Matrix.H and Matrix.CPP file (separate class) in a "Linear Algebra" folder.
However, when I run the code I get the following (linker?) error:
#include <iostream>
#include "Matrix.h"
using namespace std;
int main() {
Matrix<int> A(7,5);
int row[] = {5, 10, 9, 11, -5};
