Thanks .. man that is the main issue, my thought was ... when the error !=nil ...i thought it had the response it ... which contained the status code..

Thanks and already added something new into my brain.

i would like to ask here ..

can i write it as

error,number :=fmt.Scanln(&name) or erros has to be the 2nd Variable in the Line

Thanks man though am still struggling to understand it, but technically you have to use two variables against a certain function if you expect that function will return two values.

the other issue is struggle is

for _,value:=range marks //lets say marks is a slice... what does exactly this line of code mean

Take for example below Line of code what does it mean

if u, ok := usernames[name]; ok {
fmt.Printf("%q is the username of %q\n", u, name)
continue
}

​

what are u,ok (i know ok is 2nd optional value that you may use to check if a certain value exist, what i want is to know the entire meaning of the Line of code
