golang printf

In Go, the fmt package provides the Printf function for formatted printing. The basic syntax for Printf is:

fmt.Printf(format string, a ...interface{}) (n int, err error)

The format string specifies how the output should be formatted, using verbs that start with a percent sign (%) followed by a letter that indicates the type of value to be printed. The a argument is a variadic parameter that holds the values to be printed.

For example, to print a string, you could use the %s verb:

name := "John"
fmt.Printf("Hello, %s!\n", name)
// Output: Hello, John!

To print an integer, you could use the %d verb:

age := 42
fmt.Printf("You are %d years old.\n", age)
// Output: You are 42 years old.

You can also use other verbs, such as %f for floating-point numbers, %t for booleans, %p for pointers, and %v for any value. You can also specify formatting options, such as field width and alignment, precision, and padding.
