A question that some programmers have when passing from Java to C++ (like me) is “Which are the differences between pointers and references?“. You can find a lot of answers around developers forum, but I summarized them in the following table. Glad if you found it useful! Reference Pointer is an object...

Hash Maps with linear probing and separate chaining

Time for two new C programs! At the DSA course I learned something about Hash Tables and collision resolutions. I just implemented insert/search/print operations. The first source code is an implementation of a Hash Map with open addressing (linear probing) as collision resolution method. The following are the interesting functions of the program. As always, take a look at the source code for...
