What will be the output when the below-mentioned code snippet?
package main
import "fmt"

func main() {
num1:=25;
for ;; { //-----------------Line 1
if(num1==30){
break;
}
fmt.Printf("%d ",num1);
num1++;
}
}

Observe the below code.(Assume all the necessary imports are done/given correctly)

func main(){
customerContacts:= make([]string,7)
fmt.Println(len(customerContacts))
fmt.Println(cap(customerContacts))
}

What will be the capacity of the slice customerContacts in the above code snippet ?

var (
custName = "Stuart"+" Little" // ------------------->Line 1
age = 22
phoneNo = 7023377442 //-------------------------->Line 2

)
var city="New York" //-------------------------------->Line 3
func main() {
fmt.Println(custName, age, phoneNo)
}

What will be the output of the below code?

package main
import "fmt"
func main() {
str1 := "A"
str2 := "B"
fmt.Println((str1[0]+str2[0]))
}

What will be the output of the below code snippet?(Assume all the necessary imports are done/given)

func main() {
a := strings.Split("Hello World", "o")
fmt.Println(a[2])
}

Tom got a task to create a function to update the contact details stored in slice ‘contactDetail’ with the following numbers: “7597925446”,”7597174532”.

Complete the function ‘updateContact’ given below. (Assume all the necessary imports are given)

func updateContact(mobileNo []string) {
_______ // Line 1
_______ // Line 2
}
func main() {
contactDetail := []string{"143-676-2001 |","424-978-2469 |","202-333-1111"}
fmt.Println("Old Contact Details", contactDetail)
_______ //Line 3
fmt.Println("Updated Contact Details", contactDetail)
}

Consider the code given below and choose the correct option.
package main
import (
"fmt"
)
func recovery() {
recoverPanic := recover()
fmt.Println("From Recovery: ", recoverPanic)
}
func getValue(array []int, index int) int {
defer recovery()
if len(array) > index {
return array[index]
} else {
panic("Array Index out of bound")
}
}
func main() {
intArray := []int{10, 5, 15, 20, 25}
fmt.Println(getValue(intArray, 0))
getValue(intArray, 5)
fmt.Println("end of main")
}

What will be the output for the below-mentioned code snippet?

var prog string = " "
for ele, _ := range "Hello World" {
if(ele=='m' || ele=='w'){
prog += string(ele)
}
}
sum :=0
for index, _ := range prog{
sum += index;
}
fmt.Println(sum)
}

What will be the output for the below-mentioned code snippet?
package main
