Doubt regarding syntax

#1

for the find stl function is this the fixed syntax

auto it=find()

what i mean is that is it compulsory to use auto and it?
also can i get some sources to learn more on this??

#2

hello @ashishxmathew

no not compulsory but its easy .
example->
if we use find on vector then return iterator right? so if u dont write auto then we need to write somthing like
vector::iterator it = find()

gfg
cplus plus

#3

oh so this " it " is not a variable it is something else?? it stands for iterator?
so when we are using find we have to use “it” alongside with it right?

#4

it is like variable name and its datatype is iterator .
u can think it like a pointer.
also the name it is not fixed , u can give any name.

for example

int x=something;  // here  x is variable name and int is its type 

similary
vector<int>::iterator it=find() ; // here it is variable name and vector<int>::iterator is its datatype
#5

oh so even if we use something like say
auto x=find( );
here x is the variable and auto will recognize that it is an iterator datatype
it will still work right?? and thanks by the way.

#6

yeah auto will detect datatype on its own
