In Go, address operators are used to obtain the memory address of a variable. This allows the programmer to manipulate the contents of the variable directly in memory. The two address operators in Go are the ampersand operator (&) and the asterisk operator (*).<\/p>\n\n\n\n

The ampersand operator is used to obtain the memory address of a variable. For example, given a variable x, the expression &x returns the memory address of x. This memory address can be stored in a pointer variable using the appropriate data type.<\/p>\n\n\n\n

The asterisk operator is used to access the value stored at a particular memory address. This is known as de-referencing a pointer. For example, given a pointer variable p, the expression *p returns the value stored at the memory address pointed to by p.<\/p>\n\n\n\n
