True, but C and Fortran have very different semantics that make them suitable for very different fields. In particular, C does not have great semantics for linear algebra. Also, C has many footguns due to its use of pointers, while Fortran has virtually none.

You still need to learn the tooling, but the tooling is actually pretty similar for Fortran/C/C++ (same compiler/linker toolchain). Libraries aren't that much of a thing in Fortran, but to the extent that they are, this again is similar to C/C++.
