I was wondering why would someone use the At method to access a character at a particular index of std::string instead of a simple subscript operator?

like to access a character at the 3rd index we can simply use str[3] instead of str.At(3). Is there an advantage or disadvantage either of these posses?

There is no such method charAt in C++. – Vlad from Moscow Nov 05 '21 at 08:03
There is no `charAt` in `std::string`, only `at`. – HolyBlackCat Nov 05 '21 at 08:03

The [at](https://en.cppreference.com/w/cpp/string/basic_string/at) function performs bounds checking. – Retired Ninja Nov 05 '21 at 08:05
