apvector...Arrays

[JoshR]

Hi my name is Josh, I am new to the forums. I have been coding for maybe a year or two on and off with different languages, but have settled for c++. I have been working some assignments given to me by a friend, and I was wondering if someone could help me out. In the assignments, the header file apvector.h is used for all arrays. If anyone here is familiar with this header file, could you possibly show me how to do similar functions, but with a more universal header file, like iostream, or a vector header...how would I go about declaring a array, length, resizing, and using it in a function decleration.

Thanks,
Josh

There is a standard vector header.

#include <vector>

int main()
{
  std::vector<int> myInt;
  myInt.push_back(10); //add ten to the end of the vector
  return 0;
}

As far as declaring an array they just look like this

int main()
{
  int myArray[10]; //makes an array of 10 ints
  return 0;
}

Arrays cannot be resized after declaring their size you can use memory allocation with pointers though works just like an array.

int main()
{
  int *myPointer;
  myPointer = new array[10]; //this can change it's not stuck at 10
  delete [] myPointer;  //make sure you clean up after memory allocation
  return 0;
}

Thanks a lot!
