Go Copy 输出 The index of'd'in the slice is:3 Go Copy 在这个例子中,我们声明了一个包含元素’a’,’b’,’c’,’d’和’e’的字节切片。然后我们使用字节包提供的IndexByte函数来查找切片中’d’的索引值。该函数返回值3,即’d’在切片中的索引。 结论 在本文中,我们讨论了如何在Go...

Instead of "This expression creates a slice of the first five elements of the array a:" please say "This expression creates a slice containing elements 0 through 4 of the array a:". Then maybe explain why a[0:5] doesn't include element 5 of the array as would be expected, but only...
