Why does the IDE terminal freeze when I enter code?

Question

go

Hello, I entered this code and the terminal just freezes, I tried to delete and practice another code, everything works, but it is on this terminal that it hangs and does not display anything. Can someone explain why?

package main

import "fmt"

var a float64

func main() {
xs := []float64{98, 93, 77, 82, 83}
for y := 0; y < 5; y++ {
a += xs[y]
}

fmt.Println(a / float64(len(xs)))
}

Answer 1

Because it's an endless loop. The value of y never changes.
