Learning GO: 04 - Printing Strings

Hey! I am Currently learning Go Lang, and I am taking some basic Notes on my Notion and though I'd also just publish them here. They are not well thought out or well written but it's just me taking notes from time to time for my reference.

I am taking the Udemy Course by Maximilian Schwarzmüller,

Notes

We can format the Output Strings with Printf() Method

• there are different option to add to the output string that can format it

• here we have %v and \n that helped to add the variable value and also with \n everything after it will be on next line

• There are many of these “verbs that we can add to format, check the official docs

• We can use %.0f to round the floating numbers

• the number before f refers to the number we wanna show after the .

• so if we say %.2f that will print 2 number after .

fmt.Printf("Future Value : %v\nFuture Value (Adjusted for Inflation): %v", futureValue, futureRealValue)

Storing Formatted strings into a variable

• using the method Sprintf() we can store any formatted string into a variable and then use that variable instead of whole string

formattedFV := fmt.Sprintf("Future Value : %.0f\n", futureValue)
formattedFRV := fmt.Sprintf("Future Value (Adjusted for Inflation): %0.f\n", futureRealValue)

• after that we can use the Print() method to print these strings which will just print the string without any formatting

fmt.Print(formattedFV, formattedFRV)

Multi line Strings

• We can use backticks `` instead of double quotes to create multiline formatted string, this way

fmt.Printf(`Future Value : %v Future Value (Adjusted for Inflation): %v`, futureValue, futureRealValue)
