Reverse a string in c++

Question

I saw in a video how to reverse a string using strrev().

searching in the internet I have found that strrev() is not a c or c++ function, actually in cplusplus webpage strrev() is not there, but, why this function works in c++?

I have found that there is another way to reverse the string, using the function reverse(), both functions works, so... which one do I need to use in c++?

Answer 1

strrev() does not appear to be standard. While it may be supported by some compilers, don't use it. In fact, there does not seem to be a standard predefined function in C which reverses a string. In C++, you can definitely count on std::reverse.
