对，一个字节

• uccs #1

  int 到底是 1个字节还是 8 个字节，源码中的注释是 bytes，不是代表字节吗
  // Sizeof takes an expression x of any type and returns the size in bytes
  // of a hypothetical variable v as if v was declared via var v = x.
  // The size does not include any memory possibly referenced by x.
  // For instance, if x is a slice, Sizeof returns the size of the slice
  // descriptor, not the size of the memory referenced by the slice.
  // For a struct, the size includes any padding introduced by field alignment.
  // The return value of Sizeof is a Go constant if the type of the argument x
  // does not have variable size.
  // (A type has variable size if it is a type parameter or if it is an array
  // or struct type with elements of variable size).
  func Sizeof(x ArbitraryType) uintptr

  对，之前应该是说错了，int是64位
