Called the "pipe" symbol, it is usually located on the same key as the backslash character: \
Usually on the right hand side of the keyboard.
You need to hold down the shift key while pressing the backslash key.
Sometimes the symbolon the keybaord looks like two small vertical lines, one on top of the other.

Different fonts will make the pipe look different, however, zebada is correct.

if ((iThis >= iThat) || (iThat>= iTheOtherThing))
{
   //Do something here.
}

On my browser, those look like solid lines, however, on the command line, they look like double vertical dashes.

Note that not all computers/character sets even contain the logical or (|) symbol.  This is especially true for systems for non-english languages.   To get around this problem C++ supports tri-graphs.  These are 3 letter sequences that represent symbols that are often not supported natively.  For example, the trigraph for a single pipe character (bitwise or) or is "??!".  A pair of these trigraphs produces a pair of the symbols, which forms a logical or operator.  So you can write

if (onthing ??!??! another)

instead of

if (onthing || another)

How do you remember that stuff Nietod? Now that you mention it I recall somewhere in the dim dark days of programming on (very) non-standard keyboards I had to do that as well. But I had long ago forgotten about tri-graphs.

Nietod, do you have a list of tri-graphs? It would make for a great obsfucated piece of code :))

trigraph     replacement     trigraph     replacement     trigraph     replacement
??=     #     ??(     [     ??<     {
??/     \     ??)     ]     ??>     }
??'     ^     ??!     |     ??-     ~

That table seems to be missing the ??? trigraph which is replaced with a ?.
