| How can I use a data type that is bigger than 64 bits? |

std::bitset, or you can manually allocate stuff by manually allocating data with malloc or other stuff.
There is also another non-standard C only word that is called an "octaword"

my computer supports a 96-bit long double (12 bytes), though it might be the compiler g++.
What are you looking for this data type to support? |

| I am looking for a data type of index of an array. 64 bit indexing is small for what I am doing. |

| what do you need more than 64-bits of indexing for? 64bits should take care of any array size up to a couple of EB of memory |

| smilodon is right. I don't think you've thought through the other limits that you might encounter using such an index. |
