C++11 String Iterators vs Pointers

What are the main differences between string iterators and pointers in C++11?

String iterators in C++11 provide a safer and more flexible way to traverse strings compared to raw pointers.

Can you give me an example of using string iterators?

Sure! You can use std::string::begin() and std::string::end() to get iterators for a string. For example:

std::string str = "Hello";
for (auto it = str.begin(); it != str.end(); ++it) {
    std::cout << *it << ' ';
}

What are the advantages of using iterators over pointers?

Iterators provide better abstraction, can work with different container types, and help prevent common pointer-related errors.

Are there any performance differences between using iterators and pointers?

In most cases, the performance is similar, but iterators may introduce slight overhead due to abstraction. However, the safety benefits often outweigh this.
