Program 1:

package main

import "fmt"
import "strconv"

func main() {
	var str1 string = "123.45"
	var str2 string = "456.12"
	var num float64

	num, _ = strconv.ParseFloat(str1, 64)
	fmt.Println("Num1 : ", num)

	num, _ = strconv.ParseFloat(str2, 64)
	fmt.Println("Num2 : ", num)
}

Output:

Num1 :  123.45
Num2 :  456.12

Explanation:

In the main() function, we created two string variables. Then we converted the created strings into a floating-point number using ParseFloat() function. After that, we printed the result.


Program 2:

package main

import "fmt"
import "strconv"

func main() {
	var str1 string = "123"
	var str2 string = "456"
	var num byte

	num, _ = strconv.ParseByte(str1)
	fmt.Println("Num1 : ", num)

	num, _ = strconv.ParseByte(str2)
	fmt.Println("Num2 : ", num)
}

Output:

./prog.go:11:11: undefined: strconv.ParseByte
./prog.go:14:11: undefined: strconv.ParseByte

Explanation:

The above program will generate syntax errors because ParseByte() function is not available in the strconv package.
