The bytes array

The bytes array is a dynamic array that can hold any number of bytes. It is not the same as byte []. The byte [] array takes 32 bytes for each element whereas bytes tightly holds all the bytes together.

Bytes can be declared as a state variable with initial length size as shown in the following code:

bytes localBytes = new bytes(0) ;

This can be also divided into the following two code lines similar to previously discussed arrays:

bytes localBytes ;localBytes= new bytes (10) ;

Bytes can be assigned values directly, as follows:

localBytes = "Ritesh Modi";

Also, values can be pushed into it, as shown in the following code, if it is located at the storage location:

localBytes.push(byte(10));

Bytes also provide a read/write
