Go supports pointers, allowing you to pass references to values and records within your program. For the question of the best solution for your situation of passing around static strings, pass the string type instead of. Here, we are dereferencing our memory address to 0, then adding 10 to it. This creates mypointer as a pointer to an int32 variable, and initializes the pointer with the. It's not possible to get the address (to point) of a constant value, which is why your initialization fails.
