Problems

How do you access the 4th element of an array or slice?

What is the length of a slice created using: make([]int, 3, 9)?

Given the array: x := [6]string{"a","b","c","d","e","f"}

what would x[2:5] give you?

Write a program that finds the smallest number in this list: x := []int{ 48,96,86,68, 57,82,63,70, 37,34,83,27, 19,97, 9,17, }

Functions

A function is an independent section of code that maps zero or more input parameters to zero or more output parameters. Functions (also known as procedures or subroutines) are often represented as a black box: (the black box represents the function)

Until now the programs we have written in Go have used only one function:

func main() {}

We will now begin writing programs that use more than one function.
