package fmt
Fprint formats using the default formats for its operands and writes to w. Spaces are added between operands when neither is a string. It returns the number of bytes written and any write error encountered.

cs := charset(ch)
// special cases
switch {
case cs == "":
// unknown format
fmt.Fprintf(s, "%%!%c(big.Int=%s)", ch, x.String())
return
case x == nil:
fmt.Fprint(s, "<nil>")
return
}
...
}
Example 3 :
package main
import (
"crypto/sha256"
"fmt"
"encoding/hex"
)
func hash(c string) string {

return hex.EncodeToString(h.Sum(nil))
}
func main() {
fmt.Println(hash("abcd"))
}
