What will be the output of the following code snippet:
//Assume all necessary imports are done
const (
value1 = 10
value2 = 30
value3 = iota * 20
value4
value5 = 20
)
func main() {
fmt.Println(value1, value2, value3, value4, value5)
}

Identify the CORRECT statement with respect to the code given below:
//Assume all necessary imports are done
package main
import ("fmt")

func main() {
var a int
var b int = 2
var c = 3
d := a + b
fmt.Println(d)
}

Observe the below code:
//Assume all the necessary imports are done
func main() {

num1 := "12"
//Line1
fmt.Println(complex(float64(b), 12))

}
Choose the CORRECT option to fill Line1.

What is the output of the following code snippet?
//Assume all necessary imports are done
func main() {
balance := 1000
expense := 200
if balance = balance - expense; balance >= 1000 {
fmt.Println("Option1")
} else if balance = balance + expense; balance < 1500 {
fmt.Println("Option2")
}
else if balance = balance / expense; balance == 5 {
fmt.Println("Option3")
} else {
fmt.Println("Option4")
}
}

What possible changes in the below code so that there is no infinite looping and output of the code is: 1
Note: Assume all the necessary imports are done
(Choose 2 correct options)

for i := 0; ; i += 2 { //………Line1
if i%2 == 1 {
continue //………Line2
}
fmt.Println(i + 1) //………Line3
i++
}

Observe the code below:
Note: Assume all the necessary imports are done.
func main() {
var order = map[string]int{}
customer := "Premium"
switch customer {
case "[A-Z][a-z]{6}": //line1
order["Noodles"] = 2

case "Premium", "Regular":
order["Pizza"] = 2

default:
order["Pizza"] = 0
order["Noodles"] = 0
order["Pasta"] = 0
}
if _, flag := order["Pasta"]; !flag {
order["Pasta"] = 0
}
_, flag := order["Pasta"]
fmt.Println(flag)
}

What is the above output?

What is the output of the below code?
//Assume all necessary imports are done
func main() {
names := []string{"John", "Ron", "Leia", "Annie"}
cpNames1 := make([]string, len(names))
copy(cpNames1, names)
names[1] = "Joey"
fmt.Println(names[1] == cpNames1[1])
}

What is the output of the below code?
Note: Assume all necessary imports are done
func main() {

arr := [6]int{10, 20, 15, 2, 90, 23}
for i := 1; i < len(arr)-1; i++ {
if arr[i] >= arr[i-1] && arr[i] > arr[i+1] {
fmt.Println(arr[i])
}
}

}

What should be filled in blanks in the following code snippet?
// Assume all the necessary imports are done
func main() {
var sampleString string

modifyA := func() string {
return "FOR A BRICK, "
}

modifyB := func(text string) string {
return text + "PRETTY GOOD "
}

modifyC := func(text string) string {
return text + "HE FLEW "
}

modifyDescription := func() {
sampleString = _____<Blank>_____
}

modifyDescription()

fmt.Println(sampleString)
}

To obtain the following output:
FOR A BRICK, HE FLEW PRETTY GOOD

Consider the following code

//Assume all necessary imports are done
func main() {
filteredData := filter("apple", "banana", "cherry")
fmt.Println(filteredData)
}

func filter(data ...string) []string {
var result []string
for _, item := range data {
if len(item) > 5 {
result = append(result, item)
}
}
return result
}
Which of the following statements are true about the above program?
