Integers of Arbitrary Length
Intal is short for Integers of Arbitrary Length.
An intal (an integer of arbitrary length) is an object pointed to by a
void* pointer. An intal can be created by
intal_create() by providing a char string of a nonnegative integer provided in decimal digits. Some intals are created out of some functionalities like
intal_add(), which creates a new intal.
Responsibility of destroying the intals created lies with the client by calling
intal_destroy(), which will free whatever memory allocated during the creation of intal.
There is no theoretical limit to the size of the integer, except for memory limitations of the process (Operating System).
The operations that can be done on intals are-
- Increment and decrement by 1
How to run
- To run the sanity check
$ gcc -c intal_sanity_check.c $ gcc -Wall intal.c intal_sanity_check.o -lm -lrt -o intal.out $ ./intal.out
- Run a client file
$ gcc -c client.c $ gcc -Wall intal.c client.o -lm -lrt -o intal.out $ ./intal.out
- Test for memory leaks with valgrind
$ valgrind --tool=memcheck ./intal.out
