cointoss3000

Description

You need to toss a coin. But why settle for the best of 3? cointoss3000 gives you the best of 3000.

Dependencies

• make
• C compiler

Building

make

Usage

Typical usage (best of 3000)

./ct3

Sample output:

heads

Customise number of tosses

Simple customisation

Use -n <number of tosses>. For example, if you want the best of 3,

./ct3 -n 3

Extreme customisation

Of course, as the proud owner of cointoss3000, you won't want to limit yourself to a mere three coin tosses.

cointoss3000 is capable of tossing a coin up to (at least) 2^64 - 1 times. (Consult your C compiler's manual for the maximum number of coin tosses on your platform.) This will take a long time.

./ct3 -n 18446744073709551615

Overflows not allowed

Overflowing the unsigned long long is not allowed. Sorry, Matt Parker.

# not allowed
./ct3 -n 18446744073709551616

Overflows allowed

You can do it backwards though.

./ct3 -n -1

is equivalent to

./ct3 -n 18446744073709551615

Matt Parker, you are welcome.

Verbose

If you want to know how many heads and tails you got, pass the -v flag.

./ct3 -v

Sample output:

heads: 1546
tails: 1454
winner: heads
