hello @vishal_sangal_123
auto is a keyword in c++ , that automatically detects the datatype of variable.

example->

#include<iostream>
#incllude<vector>
using namespace std;

int main() {
   vector<int> vec(10);       // Auto deduce type to be iterator of a vector of ints.
   for(auto it = vec.begin(); it != vec.end(); vec ++)//here auto will automatically detecst the datatype
   {
      cin >> *it;
   }
   return 0;
}
```
