I am using Turbo C++ 3.2

There's your problem:

• Borland TurboC++ 3.2 dates from around 1992-1996, apparently.
  • It hasn't been updated since version 5.02 (released in 1997).
• The inline keyword was added to C in C99.
• C99 came out in 1999, which more astute readers may recognize as a year that happened no less than two years after 1997... and your version of TurboC++ 3.2, which as previously discussed, predates not only 1997, but also 1999 as well.

Solution:

• Use a C compiler released in the past 20 years that supports C99.
  • C++ compilers are not C compilers, btw.
    • While C++ inherits most of C, which means most C++ compilers support a good subset of C, they do not need to support all of C99, C11, C18, C2x, etc.
