Go Programming Language - Assessment

For the given struct, which of the following are incorrect initialization of struct instances (Select only two options)?

type Car struct{
    model string
    brand string
    yearOfProd int
    isInsured bool
    status string
} 

What will be the output in the following code snippet?

package main

import "fmt"

func compareString[T any](function func(T, T) T, slice []T) T {
	result := slice[0]
	for index := 1; index < len(slice); index++ {
		result = function(result, slice[index])
	}
	return result
}

func main() {
	stringSlice := []string{"Famous Five", "Hardy Boys", "Nancy Drew"}
	modifyFunc := func(value1, value2 string) string {
		if len(value2) > len(value1) {
			return value2
		} else {
			return value1
		}
	}
	result := compareString(modifyFunc, stringSlice)
	fmt.Println(result)
}

Consider the slice list given below.

Identify the Go code to be written at Line 1 such that the output is [ java programming ]

package main
import(
    "fmt"
)

func main(){
    myCourses := []string{"python","java","go","programming"}
    newSlice:=myCourses[3:]      
     
    #Line1_______________________________ 
    fmt.Println(slice1)
}

What’s the output of the following code?

package main
import "fmt"
func main() {
	var flagA int8 = 3
	var flagB int16 = 4
	sum := flagA + flagB
	fmt.Println(sum)
}

What’s the output of the following code?

package main
import "fmt"
const (
    varA = iota
    varB = iota
    varC = iota
)

const (
    varD, varE, varF = iota, iota, iota
)

func main() {
    fmt.Println(varA, varB, varC, varD, varE, varF)
}

What is the output of the following code snippet?

func main() {
  sliceX := [...]int {1, 2, 3, 4, 5}
  sliceY := sliceX[0:2]
  sliceZ := sliceX[1:4]
  fmt.Print(len(sliceY), cap(sliceY), len(sliceZ), cap(sliceZ))
}

Predict the output of the following code snippet.

package main

import (
	"fmt"
)

func sport() {
	fmt.Printf("In sport function->")
}
func getSport(arr []string, ind int) string {
	sport()
	if len(arr) > ind {
		return arr[ind]
	} else {
		panic("Index out of bound")
	}
}
func defFunc() {
	fmt.Printf("Deferred Function called->")
	re := recover()
	if re != nil {
		fmt.Printf(" Error from Recovery : %v", re)
	}
}
func main() {
	defer defFunc()
	sportArr := []string{"Cricket", "Hockey", "Football"}
	getSport(sportArr, 3)
}

Which of the following options will be the correct function declaration (at Line1) for the given code snippet and sample output?

Code Snippet:

type car struct {
    name string
    brand string
}

__________//Line1__________ {         
    newCar.name = "Civic"
    newCar.brand = "Honda"
}

func main() {
    setCar := car{                  
      name:    "Celica",
      brand: "Toyota",
    }
    setCar.carSwap()                   

    fmt.Printf("Your current car is: %v %v", setCar.brand, setCar.name)
}

Sample Output:

Your current car is: Toyota Celica

Which of the following statement is/are true?

1. The length and capacity for an array are always equal.
2. The length and capacity for a slice are always equal.

What will be the new content of the slice “carModelSlice” after the following operations:

carModelSlice:=[]string{"AE86_Trueno","FC_RX7","Supra","Levin_AE85","Skyline","Chaser_JZX100","Silvia_S15"}
	
carModelSlice = append(carModelSlice[:3], carModelSlice[4:]...)
carModelSlice = carModelSlice[2:6]
