It allows for allocation and deallocation of memory at runtime.
Heap can become fragmented over time, leading to performance issues.
Examples include malloc() and new() in C++.
- Q5. Explain Hashing.
- Ans.
Hashing is a process of converting data into a fixed-size output using a mathematical function.
Hashing is used for data integrity and security purposes.
Hash functions are one-way functions, meaning it is difficult to reverse engineer the original data from the hash value.
Hashing is used in password storage, digital signatures, and data comparison.
Examples of hash functions include MD5, SHA-1, and SHA-256.
