class description (MyString):

class defines a sequence of characters (similar to class string). The implementation must be as an array of characters that are dynamically allocated and resized as necessary. You must use a null character to terminate the string - just like C-strings are null terminated.

deafult constructor:

Code:

/// get_length(char *s) gets length of s before null character. buf is private

A constructor to a class takes some arguments including a pointer which is assigned to a class variable. The constructor then calls a default constructor, but inside the default constructor the pointer is no longer valid.

some code should illustrate.

Code:

Feature::Feature(){
    cout<<"at b "<<oc<<endl;
    cout<<"b is "<<oc->geoSphere->getNumVs()<<endl;

Hi,
I was just wondering how the new operator (in C++) knows how much memory to allocate when creating an object of a class such as shown below:

i.e

class Books
{
...
}

int main()
{
....
Books textbook = new Books();
....
}

I have a stronger C background and I know that in C we have to specify the memory size for...

take following class and two object definitions:

Code:

class Rect{
 public:
  enum centimeter;
  enum meter;
  Rect(double len,double wid,enum centimeter){
   length=(len/100);
   width=(wid/100);
  }
  Rect(int len,int wid,enum meter){
   length=len;
   width=wid;
  }
  //rest of implementation
 private:
  double length;//in meters

...

take two following classes and their constructors as samples:

Code:

class One{
 public:
  One(int a,int b):adad1(a),adad2(b){}
 private:
  int adad1;
  int adad2;
};
class Two{
 public:
  Two(int input[]){
   for (int i=0;i<10;i++)
    araye[i]=input[i];
  }
 private:
  int araye[10];
};

considering objects with static...

Suppose we have following two classes:

Code:

class Temp{
 public:
  char a;
  char b;
};
class Final{
 private:
  int a;
  char b;
  char c;
 public:
  Final(Temp in):b(in.a),c(in.b){}
  //rest of implementation
};

can we initialize an object of the Final class with following syntax in upcoming c++0x standard:
Final obj(Temp{'a','b '}...

I created a rational class, created member functions to add, subtract, multiply and divide. The reduction function however doesn't work. And the Dev cpp compiler gives a linker error. I have attached the header, implementation and the driver file in rational.zip
Could you help me fix this code?
What am I doing wrong?...

Hullo, I've been learning C# and I had a question. I'm creating a class, and I was writing the constructor. When I was assigning values to it's variables, I found that the compiler seems to take it both with and without the "this" keyword. Does it make a difference whether I use it or not?

[CODE=C#]public class Car
{
private float weight, gasTank;
public Car(float myWeight, float myGasTank)...

Problem with my class, "cant find symbol on my constructor"?

C++ constructor help!!

Pointer gets lost when calling one construction from another

How does new know how much memory to allocate??

does adding a dummy parameter to constructors of a class to solve calling ambiguity,

which kinds of constructors may be applied during compile time as optimization.

Will this initialization syntax be valid in upcoming c++0x standard ?

Rational Class help. Reduction funtion doesnt work. Linker error in Dev cpp.

What is "this" in object constructors?
