Go data types are divided into basic and composite data types. The basic data types include numbers, strings and Boolean types. They are the basic building blocks of our data. The composite data types consist of arrays, structs, pointers, functions, interfaces, slices, maps and channels. These eight composite types use the basic types to build more advanced constructs and structures. In Go, both signed and unsigned integers are available in the 8-bit, 16-bit, 32-bit and 64-bit formats. If we don't specify a size and just declare an int, then its size is either 32 bit or 64 bit according to the platform we are compiling for. This table shows the name, size and range of each type. There are two further integer type aliases.…
