A quite simple generator of left truncatable primes (http://en.wikipedia.org/wiki/Truncatable_prime). This was made as part of an exercise / job interview. It was written in old style ANSI C.
It can be compiled with GCC by simply executing: gcc -o outputFile LeftTruncatablePrimeGetter.c -ansi -pedantic
The usage of the program is pretty simple and can be reminded by calling the program without arguments or with '--help'.
A simple example calling would be: outputFile 100
And it would return: 5167
The output for test purposes is returned along with the time elapsed in program execution.
