What are the differences in memory allocation techniques?

There are mainly two types of memory allocation: static and dynamic. Static allocation occurs at compile time, while dynamic allocation happens at runtime.

Can you explain static memory allocation in more detail?

Sure! Static memory allocation reserves memory at compile time, meaning the size of the memory must be known beforehand. This is typically used for global variables and arrays.

What about dynamic memory allocation?

Dynamic memory allocation allows for memory to be allocated at runtime using functions like malloc in C or new in C++. This provides flexibility but requires careful management to avoid memory leaks.

What are the advantages and disadvantages of each?

Static allocation is faster and simpler but less flexible. Dynamic allocation is more flexible but can lead to fragmentation and requires more overhead.
