In Solidity programming the type of each variable whichever that is a state or local variable needs to be specified. Solidity delivers many elementary types that can be linked to make complex types. The types may relate to each other in languages covering operators. A data type permits the compiler to check the accurate use of the variables.
A solidity programmer must know that Byte states to 8 bit signed integers. The whole thing in memory is stored in bits containing binary values—0 and 1. Solidity similarly makes available the byte data type to store information in binary format. Usually, programming languages have a single data type for representing bytes. On the other hand, Solidity has numerous flavors of the byte type. It gives data types in the collection from bytes1 to bytes32 wide-ranging. This is to indicate changing byte lengths, as required. These are named fixed-sized byte arrays. These are applied as value types. The bytes1 data type signifies 1 byte and bytes2 represents 2 bytes. The default value for byte is 0x00. The default value gets prepared with this value. Solidity likewise has a byte type that is an alias to bytes1.
A byte may be allocated byte values in hexadecimal format, as follows:
bytes1 aa = 0x65;
A byte may be assigned integer values in decimal format, as follows:
bytes1 bb = 10;
A byte can be allotted negative integer values in decimal format, as follows:
bytes1 ee = -100;
A byte may be assigned character values as follows:
bytes1 dd = ‘a’;
A value of 256 cannot fit in a single byte and needs a bigger byte array in the below code snippet:
bytes2 cc = 256;
The code citation in the following screenshot displays how to store binary, positive, and negative integers and character literals in fixed-sized byte arrays. We may similarly achieve bitwise operations for example and, or, xor, not, and left and right shift operations on the byte data type:
