How to convert octal to hexadecimal in Golang 1.20
0In this video we are going to generate source code for the GoLang Program, How to convert octal to hexadecimal using chatGPT.
After generating we will verify and run the generated code.
IMPORTANT NOTE on SOURCE CODE: only source code that are acceptable by the youtube description box will be displayed.
##############SOURCE CODE#########################
package main
import (

"strconv"
)
func octalToDecimal(octal int64) int64 {
decimal := int64(0)
base := int64(1)
for octal != 0 {
remainder := octal % 10
decimal += remainder * base
base *= 8
octal /= 10
}
return decimal
}
func decimalToHexadecimal(decimal int64) string {
return strconv.FormatInt(decimal, 16)
}
func main() {
var octal int64
fmt.Print("Enter an octal number: ")
fmt.Scanln(&octal)
decimal := octalToDecimal(octal)
hexadecimal := decimalToHexadecimal(decimal)
fmt.Printf("Hexadecimal equivalent: %s", hexadecimal)
}

Below is the explanation for the program:
Explanation:
We start by importing the fmt and strconv packages. fmt provides functions for formatting and printing data,
while strconv provides functions for converting strings to various numeric types.
We define a function octalToDecimal that takes an int64 octal number and returns its decimal equivalent as an int64.
The function uses a loop to convert each digit of the octal number to its decimal equivalent, and accumulates the result in a variable called decimal.
We define a function decimalToHexadecimal that takes an int64 decimal number and returns its hexadecimal equivalent as a string.
The function uses the strconv.FormatInt function to convert the decimal number to a hexadecimal string.
In the main function, we declare a variable octal to hold the octal number entered by the user.
We use fmt.Scanln to read the input from the user and store it in octal.
We call the octalToDecimal function to convert octal to its decimal equivalent, and store the result in a variable called decimal.
We call the decimalToHexadecimal function to convert decimal to its hexadecimal equivalent, and store the result in a variable called hexadecimal.
Finally, we print the hexadecimal equivalent using fmt.Printf.
That's it! The octalToDecimal function and decimalToHexadecimal function are the key parts of this program,
as they perform the actual conversion from octal to decimal and from decimal to hexadecimal, respectively.
