  • %.2f: This limits the floating-point number to two decimal places.In our code, is limited to only 2 decimal places.

fmt.Sprintf offers a concise and readable way to incorporate variables into strings, enhancing code clarity. It's especially useful for outputting data in a more engaging and informative manner. Through practice, you'll become comfortable with this skill, which is crucial for effective Go programming.
