Variable formatting with the fmt package | Smart Go

The video tutorial introduces the FMT package in Go, focusing on functions like print, Println, and Printf for console output and string formatting. It explains how to use formatting codes for detailed control over output, including binary and hexadecimal formats. The tutorial also covers Sprint functions for string manipulation and highlights the importance of matching variable types with format codes. Additionally, it discusses precision control for floating-point numbers and encourages exploring more formatting codes on the Golang website.

What is the primary function of the Print and PrintLn functions in the FMT package?

• To format variables for file output

• To print variables to the console

• To compile Go programs

• To convert variables into JSON format

How does the Printf function differ from Print and PrintLn?

• It is used for error handling

• It allows for detailed formatting using codes

• It compiles the code

• It only works with strings

Which format code would you use with Printf to display a number in hexadecimal?

• %s

• %d

• %v

• %x

What is the main advantage of using S-prefixed functions like Sprint?

• They compile the code

• They print directly to the console

• They handle errors automatically

• They return a formatted string

What happens if you use a format code that doesn't match the variable type in Printf?

• The program compiles successfully

• The variable is automatically converted

• The output is incorrect but no error is shown

• A runtime error occurs
