(at least i hope so...) |

Here are some (hopefully useful) c++ snippets/libs/helperthingies. |

|

Probably all are header only, with a main.cpp for testing. |

Stuff probably needs some C++0x features. |

Make sure your type is copyable by just copying it's memory-region. |

``` |
|||
The default arguments make it use `std::cout` and an empty string as input. |
|||
|
|||
|
|||
You can also use a string as input: |
|||
brainfuck(",[.,]", "input"); |
|||
brainfuck(",[.,]", "input"); |
|||
|
|||
Or with a stream/container/iterator: |
|||
brainfuck(",[.,]", std::input_iterator<char>(std::cin)); |
|||
brainfuck(",[.,]", std::input_iterator<char>(std::cin)); |
|||
|
|||
|
|||
You can specify the memory-units: |
|||
brainfuck<int>("..."); |
|||
brainfuck<int>("..."); |
|||
As long as the type has certain operators. The default output is comma-seperated, except for char. |
|||
|
|||
|
|||
You can specify an output-iterator: |
|||
brainfuck("...", "", std::back_inserter(my_vector)); |
|||
brainfuck("...", "", std::back_inserter(my_vector)); |
|||
|
|||
|
|||
It has a lot of defaultparameters, because it's intended use was on an irc-channel. |

"for(auto x : counted(v)) { ... x.value ... x.index ... }" |
|||
x.value is a reference to the element in the container (so you can change it's value), x.index is what it is. |
|||
Container should have forward iterators. |
|||
|
|||
|
|||
This headers is purely a handy tool for the range-based-for-loops (ie "for(auto x : counter(v))"). Using it explicitly with iterators is not recommended! |
|||
|
|||
|
|||
There is no const version of it. Doing "for(const auto x : counted(v))" doesn't make it impossible to change x (so the element in the container can be modified). |
|||
|
|||
|
|||
Example: |
|||
for(auto x : counted(v)) { |
|||
std::cout << "v[" << x.index << "] = " << x.value << std::endl; |
|||
x.value *= 2; |
|||
} |
|||
|
|||
This will output the container v, with it's indeces. And it will multiply every value in v by 2. |
