printf by default writes on stdout , if you want to write to a specific stream you should use fprintf which accepts a FILE* as the destination stream. Also it's "std" out because it's called "standard" output.
Faraz Karim. The fmt. Println function in the GO programming language is a function used to print out a formatted string to the console. fmt. Println does not support custom format specifiers, which means only the default formats are used to format the string .
fmt stands for the Format package. This package allows to format basic strings, values, or anything and print them or collect user input from the console, or write into a file using a writer or even print customized fancy error messages. This package is all about formatting input and output.
stdout is a file that is printed immediately to the screen by the console.
From the documentation:
Print formats using the default formats for its operands and writes to standard output.
So yep, it writes to stdout.
Yes, it does. From the source code:
// Print formats using the default formats for its operands and writes to standard output.
// Spaces are added between operands when neither is a string.
// It returns the number of bytes written and any write error encountered.
func Print(a ...interface{}) (n int, err error) {
return Fprint(os.Stdout, a...)
}
os.Stdout indeed represents the standard output stream.
From the Print documentation: Print formats using the default formats for its operands and writes to standard output.
