"as of 2022 programs have been written in Fortran for over six decades and there is a vast body of Fortran software in daily use throughout the scientific and engineering communities.... It is the primary language for some of the most intensive super-computing tasks, such as in astronomy, climate modeling, computational chemistry, computational economics, computational fluid dynamics, computational physics.... Since the early 2000s, many of the widely used support libraries have also been implemented in C and more recently, in C++... For this reason, facilities for inter-operation with C [1] were added to Fortran 2003 and enhanced by the ISO/IEC technical specification 29113, which was incorporated into Fortran 2018...
