here is the code i have so far, basically you have ti enter a price in pounds and it will convert it to euros. i have got the conversion working i am just unsure how to get the euro symbol for the out put.
#include <iostream>
#include <iomanip>
#include <cassert>
using namespace std;
int main() {
char answer;
float sumInEuros;

I am completely baffled by bin file read/write and positioning. Here I wish to search a chemical name info by symbol. Here is my struct
struct chemicalElement {

char name[118];
char symbol[3];

};
I successfully wrote to file.dat as binary but having problem in reading and searching...here is my func...
void searchSymbol(char sym, chemicalElement chemEl[]){
ifstream binFile;
unsigned short int i=0;
binFile.open("chemicalEl.dat", ios::binary);
if(binFile.good())
cout<<"File read for search"<<endl;

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'm building a cross-platform library which links to some other 3rd party libraries at run time (i.e. on Windows, the other libs will be available as DLLs whereas on Linux / OS-X etc they'd be shared objects, which are similar). For the sake of argument, one of those libraries is called "jack".
Obviously, our app can't guarantee which version of the other libs will be on the user's system (or even that they'll be installed at all). So our code is littered with statements like this:-
Code:
if (!jack_port_type_get_buffer_size) {
warning << _("This version of JACK is old - you should upgrade to a newer version") << endmsg;
} else {
some_var = jack_port_type_get_buffer_size();
}
We link to the latest version of jack, where that symbol is declared like so:-
Code:
size_t jack_port_type_get_buffer_size();
One problem is that it doesn't even seem to be an exported symbol (although that wouldn't affect the other platform builds). But apart from that, our customer might have an old copy of jack installed or even no copy! We seem to be making the assumption that if our customer has an up-to-date version, jack_port_type_get_buffer_size will be set to a valid address - but in all other case it'll be magically set to zero (there's nothing in our code that sets it to zero).
If there are two projects A and B. A is created as .dll, while B is created as static library.
project A has a class "classA"
classA: public classB {
public:
testA();
};
project B has a class "classB"
classB {
public:
testB();
} ;
I want to make a symbol of classB::testB() in A.exp (like ?testB@classB@@QAEXXZ), can I do it by using __declspec(dllexport)?
Also if I make classB as a template class, can the symbol of classB::testB() be generated automatically in A.exp when building project A?

How can I fix this issue?
I have such task. There is such alpahbet as {a, b} in markow algorithm concept. So I need to find out which letters (a or b) are more in word "p". If a then to retrieve the word with letter a, if-b-then word with letter "b", if there is equal quantity then 0. How to do it. Where to find such example, at least some clues how to begin.

So even though I have so many issues with linking libraries, I apparently became the go-to person for a fellow college friend of mine for a sql library. He's using the mysql connector/c++ and his team has had quite a few issues getting it set up. I've solved two out of three issues:
1st issue I solved was that they didn't know how to build boost, I just linked it and they were good to go.
2nd issue I solved was that they were missing libmysql.lib, I just installed the mysql server onto their computer and linked that up. 3rd issue is where I am now stumped at, as they get a compile error: LNK2001 unresolved external symbol: _get_driver_instance().
