Code Challange

C# Logger in Gohallange -1

Define a simple logging interface named Logger with three methods: Info, Warning, and Error. It also provides an implementation of this interface using a Log struct, which has a field for an os.File to write logs to.

Logger Interface

The Logger interface has the following methods:

• Info(message string): Prefixes the message with "[info]".
• Warning(message string): Prefixes the message with "[warning]".
• Error(message string): Prefixes the message with "[error]".

Log Struct

The Log struct implements the Logger interface and has a field named file of type *os.File representing the log file.

NewLog Function

The package provides a function named NewLog that creates a new Log instance with the specified filename.

Solution

See the provided Go program in the file logger.go.

Challange -2

Define Go program that reads a text file containing data in the format "key:value" on each line. It parses the file and populates a map with the key-value pairs. It also handles any errors that may occur during file reading or parsing.

Usage

1. Make sure you have Go installed on your system.
2. Clone this repository or copy the contents of main.go into a new Go file.
3. Modify the filePath variable in the code to point to your input text file.

solution

See the provided Go program in the file parser.go.

Challange -3

Create a Go program that performs the following tasks:

1. Read a JSON file containing a list of employees with their respective salaries.
2. Implement logic to give a 10% raise to employees whose salary is below the company average.
3. Write the updated employee data back to a new JSON file.

Requirements

• The program should be written in the Go programming language.
• The input JSON file should follow the structure defined by the Employee struct.
• The program should calculate the average salary of all employees.
• Employees with salaries below the average should receive a 10% raise.
• The updated employee data should be written to a new JSON file.
