Which of the listed operations will cause a compilation error in Go? Comparison of two arrays of the same length and type: [3]int == [3]int Pointer comparison with nil: p == nil Assigning byte to a uint8 type variable Comparison of two slices: []int == []int

A compilation error in Go will be caused by comparing two slices: []int == []int. In Go, slices cannot be compared directly using the == operator, except when comparing with nil.

Explanation by points:

• Comparing two arrays of the same length and type [3]int == [3]int is allowed, as arrays are compared element-wise.
• Comparing a pointer with nil (p == nil) is correct.
• Assigning a byte to a variable of type uint8 is correct, as byte is a synonym for uint8.
• Comparing two slices []int == []int will cause a compilation error because slices cannot be compared directly.

Example of the error:

var a, b []int
if a == b { // Compilation error: invalid operation: a == b (slice can only be compared to nil)
    // ...
}
