The bovious thing to do is to run it in the debugger e.g. gdb or ddd
Compile with g++ -g -o Prog prog.cpp, and the run as ddd Prog. When it hits the seg-fault, use up until you see the problem...

Well you don't seem to have written a operator>> for class ballTeam. I could be wrong since you didn't include the definition files (.h files).



I

I am not going to deal with all the things that are wrong here

They include:

(a) a missing = in a test else if (opr1 ='(')[/icode[
(b) stupid reassignment [icode]ifx[i] = ifx[i+1]; but loop...

Seriously, you are just going round in circles. You HAVE TO WRITE SOMETHING SIMPLER so that you get to grips with variables/ if else constructions / functions. And you are going to have to do it in...

This is code absolutely begging for a loop!!

Your actual problem is that you test x then y. That is incorrect. (I think)

Consider a box with coordinates (0,0) and (10,10). I.e it is a square of...

If you have a problem like that and don't understand the compiler error, then split the function into bit, e.g. calculate without the sqrt e.g.


double d=a+b;
distance=sqrt(d);


You have...

The problem you have is temporary values and what happens to them:
I think this will be clear (I hope :)

The problem is that your are taking a copy of the value in the list. This does indeed...

The first problem is that your are returning a string from a function that says it will return a floating point number..
e.g. points has returns "miss" But requires it to return a floating point...

If you are debugging code (and that is what you are doing here), you need to step through the code and check your assumptions. That can be done with a traditional debugger that lets you see each line...

First things first: Dont use system("Pause") it has been discussed to death here and everywhere on the web.

Second: The next problem is that you are using temp1 without initializing it. i.e every...

Calling the destructor normally implies that the memory is listed as free, i.e. you can quickly find that the memory is corrupted with something else.

Try valgind to get a detailed picture of...

Let use be a little careful here about the sequence of events.
First off, if you examine the assembler/machine code that is 100% exactly what is going on. However, (a) that may mean that your...

firstPerson's answer works and solves the problem BUT for a large classes you might prefer to use explicit instantiation. [which gives the beginner a better idea of what is happening (sometimes)].
...

What about adding a class. Starting with that is a great way to group data together.

class UserInfo
{
private:
std::string Name;
std::string Pass; // THIS IS NOT SECURE
...

The reason (for good/bad) is that when the compiler hits instances.inc.
It has not seen the definition of graph.
If you put include instances at the end of graph.cpp all is fine.

Note that you...

It doesn't have an inbuilt function (but I am sure they are in libraries)
BUT surely it is this

int totalMin=890;
int min=total % 60 ;
int hour = (total / 60) % 24;
// etc


not exactly...

You seem to have two cin>>x in your code at lines 23 and 21. I would delete line 23.

I might make count and integer but that is minor.
you have remembered to initialize your variables which is...

Yes the problem is name reuse. The code compiles fine if you cahgne the name OR you put allocator in a namespace e.g

namespace X
{
template<class T>
class Allocator{

public:
...

Well this looks like a c program (not a c++) so I will assume that you are in C and carry on.

The first question is that you have unfortunely added a \n after the %d in the scanf statement. That...

Well ok then don't word the problem as if it is verbatim from the question sheet. Doesn't matter were you are tell us what you have got.

The problem can be broken down in to several parts (a)...

That doesn't sound useful idea. Consider this

(a) A polynomainal multiplication is a N * M process were the length of the polynominial are M and N.
(b) The polynominal can be sparse e.g. x^8+x. ...

Welcome to the real world. There is not free lunch.... sorry.
So
(a) either attend your classes and actually pay attention.
(b) decide that the class is not a good use of time and...

You could use some of the object orientation stuff , i.e. if all the variables in an object are private, then you can add a flag that they have been changed, when they are accessed via the...

Tough. Try telling that to the standard committee. Section 13.10 tells us that when an template is explicitly instantiated it is necessary to create ALL the methods. Additionally the compiler is no...

Sorry my fault about not being clear about point 1.

your code is

template <class E>
nodePtr<E> BinaryTree<E>::getNode(E item){
nodePtr<E> temp = new nodePtr;
temp->data = item;
return...

Basically your template instantiation is in the wrong piece of code.
It should be in the Temp.cpp.

Why: To create an instance of a class you have to have all the methods available to the...

It is that your decrement of y does absolutely nothing.

total start as???? Absolutely anything.

Your function is not recursive, it doesn't call itself. Imagen you call your function like this...

Your problem is the subtraction of y. It doesn't do anything.

The point about recussion is that in a default case you
return a value e.g. if (y==1) return x;
but in more general cases you...

(1) It is not pointless to use templates just that it is better to use references.
(2) However, designed the class didn't design it well enough to compile so it that is sufficient excuse then...

Ok first USE CODE TAGS. Sorry to shout but it is written in the introduction to the forum, it is written as the top announcement to this and almost every forum. e.g...

Just a quick note, since you look like you are going to get confused.
You really need to be working with double or floats, e.g.
3.4 or 34003.384 or 1.87561e2. Even if you input standard integers ...

I think you need either:

while(Choice!='n' && Choice!='N') { }

Note the && (and).

OR:
while(tolower(Choice)!='n') { }

Also please note you are very unlikely to need the ; after the while

First off, shurik_r got most of that correct, however, you cannot use
typedef for unspecified templates , so you cant write

// THIS IS NOT ALLOWED
template <class E>
typedef node<E>*...

The normal way to do this is to use a stringstream.
Now you have to be VERY VERY careful, with this.
The reason is that if you do

double Res;
std::string A="3.4e5x"
std::stringstream IX(A);...

You can compile everything as separate files BUT to get an executable you need to link all the files required.
e.g. in three command do this:

g++ -Wall -c Taddmain.cpp
g++ -Wall -c Tadd.cpp...

Ok there are many many thinks to really really dislike about this code.
In particular is the "cleverness".

Ok first, it is int main(). That has been said a million times on this forum.
...

The problem is that you have a map of type
map<string,list<pointer> >.

You are doing two thing wrong:

std::map<std::string,std::list<Operation *> >::iterator labelPtr;
labelPtr =...

well then the first thing to do is to find out if you get to your first system command. Put a std::cout<<"TEST"<<std::endl; exit(1) at line 17 of your main. Then see if you get that without a seg...

Actually, if you are doing a binary search, make 100% certain that you understand the algorithm in 1D. That is important since 2D array can be easily thougth of as a 1D array. The binary search can...

Note 100% certain I follow what you are trying to do.
But some points:

(a) C++ is almost space insensitive. The only areas you have to worry are in the middle of keywords e.g. cla ss A { } is...
