Help on definitions

I need help in the following definitions: ptr, foo.

Personally, I thinks its all to easy to get carried away with over-decoration of variable names.

... What he said.

Variable names along the lines of m_sprgszName are just painful.

One other fairly common practice is to have pointer typedefs. If you hade a linked list, and dealt mostly with node*s instead of nodes, you might have:

typedef node* node_ptr;

foo is just a common arbitrary name for something, often a function. It is commonly used in combination with another name called bar:

Code:

---

#include <iostream>
using namespace std;

void foo()
{
  cout << "Hello" ;
}

void bar()
{
  cout << " World!" << endl;
}

int main()
{
  foo();
  bar();
  return 0;
}

I suppose you could use somehting like jumpin and jehosephat instead of foo and bar, but foo-bar has some funny historical implications, sorta like "Kilroy was here", so it has just stuck.
