The fmt library formally known as CppFormat is an open-source formatting library for C++ language. We’ve seen it can be used as a drop-in replacement for
printf and the C++ IOStreams.
Here we have taken time to point out that this is just a name change to fmt and does not change anything within the library or its APIs. The main change of name is to match the internal library namespace naming conventions used to access the APIs. You can read more details on our overview of this library here.
To download fmt you can go to the official website to download the library.
