Hi, i need to write a code which can convert a raw image to anyother desired format like BMP or JPEG etc.

what is a bitwise copy in c++ done by default constructor and what is shadow copy and deep copy ?

Hi, when i write the following, kindly guide me that the type of pointer *p and also the type(A or B) of object made in the same line (line 3). Class A {} Class B : public A {} main () { A *p = new B; // line 3 }

i have a code from one of my past papers n it was asked to put the reason that what was wrong with that code. i looked on it very much but didnt find any problem. following is the code, kindly tell me even if there is any efficiency or any other drawback in this code. class A { int *pi; public: A() { pi = new int; } };

plz somebody tell me whats the problem with this little example? i get an error Error 1 error LNK2019: unresolved external symbol "public: __thiscall B::B(void)" (??0B@@QAE@XZ) referenced in function _main #include <iostream> using namespace std; class A { public: A(); ~A(); }; class B : public A { public: B(); ~B(); }; int main() { A *p; p = new B; // ... delete p; }

yes, n it is eclipse itself i guess

Hi, whenever i run any code of C++ in Eclipse, it says binary not found??

Is there any automated way of doing indentation in my lengthy code?? i mean is there any option available in eclipse or either in Netbeans??

I have installed Netbeans for C++ but i think it requires a separate installation of compiler also, kindly guide me from where can i download a free compiler of C++ for NetBeans IDE 6.9.1 (Build 201007282301)

ok, then what is going on here please? class A { public: A() { cout << "(1)"; } A(A &a) { cout << "(2)"; } }; class B { A a; public: B() : a() { cout << "(3)"; } :confused: }; … B b; B b2(b);

i want to know what is ":" operator in C++ called. i know how it is used in access specifiers but i saw something new for me. destructor.hpp class A { int i; public: A(); // A(int a);// ~A(); // }; destructor.cpp #include "destructor.hpp" #include <iostream> using namespace std; A::A() : i(0) // WHAT IS ": i(0)" ?, WHAT IS ":" MEAN HERE ? :confused: { cout << "default constructor of A" << endl; } A::A(int a) : i(a) { cout << "constructor of A(" << i << ")" << endl; } A::~A() { cout << "Destructor of A (i=" << i << ")" << endl; }

I have this version of eclipse but i didnt find Debug single step option anywhere, kindly guide me. Eclipse IDE for Java Developers Version: Helios Service Release 1 Build id: 20100917-0705

is there any software through which i can understand the flow of any code? or can have any diagrammatic view?

i want to study a code, a difficult n lengthy code, n was wondering if there is any option in any of these through which i can run the code step by step (simulator will run each step of the code n stop n then run the next one, like breakpoints) to get a better understanding of my program/code flow? which one is suitable n what is the name of such option?

Hi, m a beginner for java, n i wanna know which simulator/editor is good for doin java programming plz.

Need urgent help in assignment of JAVA, any idea suggestion plz I need help in my JAVA assignment plz. kindly guide me any technique/idea to do the following. m not at advance level of programming. i already have the initial part of my assignment completed which is to make a simple command line calculator. this is the next part. The program should take function definitions and those definitions can be used in future expressions for eg: def add(x,y)=(x+y) >>> ok def inv(x)=1/x >>> ok inv(add(2,2)) >>> ans : 0.25 Also four additional commands: show; to prints all de?nitions on screen save flename; to save all defnitions in a fle load flename; to load all definitions from a fle delete funname; to delete the defnition corresponding to the function named funname
