However, STD provides efficient and deterministic ways to manage resource such as object ownership and reference counting.Influenced byB (BCPL,CPL), ALGOL 68, AssemblyC, Simula, Ada 83, ALGOL 68, CLU, MLAppeared in19721985ClassesUses structures instead, and hence bestows more liberty to use internal design elementsclass and structOOP (Object Oriented Programming)Not built in; freedom to setup structures to act like objects. Lacks the ability to declare encapsulation.Built in; size and memory layout of objects is deterministic.
The VCC is the positive power input (5V) and GND is the negative (or ground). Pins 17, 18, and 19 are used by the SPI to program the chip, if it does not have a bootloader. Digital pins are capable of both I and O interfaces, in other words, they can either output power (ex. Light an LED), or receive power (ex.

C is a language that allows direct access to low-level resources. It was originally built to implement the Unix OS, so by its nature it allows you to do things at a system level - which is convenient for exploits.A consequence of this is that compiled C programs often don't need external dependencies - as is pointed out by in the comments.C was originally built on top of C, and has the same access to low level operations.As an example, C allows for direct manipulation of memory through pointers. Once a pointer is created, it can be added to or subtracted from to point at other memory locations. With a little creativity, this can be used for nefarious purposes.By contrast, Java and C# do not allow this type of manipulation. They do not allow a user to add or subtract to a so-called reference variable (the Java and C# equivalent of C's pointers).Traditionally, C and C are translated directly into machine code, whereas many modern languages such as Java and C# are translated to code for virtual machines (JVM and CIL code).
Compilers that translate C and C directly to machine code are readily available on almost every platform; less so for compilers that translate Java or C# directly to machine code.
