WHAT IS AUTO ID? SIR USED IN FIND STL

Hey @dhruvilcodes
auto is keyword which is used in C++ for runtime identification of datatype. So if you use this then you don’t have to worry about writing correct datatype. It will automatically assign it.
For eg:- you need to iterate a vectorv then you can easily do it with less typing.

for(auto x : v) {  //now x is vector<int> type
       for(auto y : x){  //y is int type
             cout<<y;
       }
}
