Functions
Printf
In this example, fmt.Printf
formats and writes to standard output:
fmt.Printf("Binary: %b\\%b", 4, 5)
Binary: 100\101
Sprintf (format without printing)
Use fmt.Sprintf to format a string without printing it:
s := fmt.Sprintf("Binary: %b\\%b", 4, 5)
No output but the value is :
s == 'Binary: 100\101'
