turbo c++ is too old, i bet nobody use it
try a new compiler, Visual Studio is very good.
if your teacher asked you to use Turbo C++ then use it if you don't care about being a good programmer in the future.
i'm studying Communication engineering(however i don't like it but my marks wasn't good in high school thats way i had no other way except accept it) we had a c++ leacture in first year
my teacher asked us to use Turbo C++ but i used Visual Studio instead however it cost me to lose some marks but i'm happy i didn't follow him :D
Probably the easiest answer is just to get CodeBlocks.
And also, do not use Turbo C++, it is way too outdated to be relevant or worth using. This is a very old IDE that uses a pre-standard C++ compiler. Do not use it. And if it was recommended to you by your teacher, tell him that he should update his 20 year old (or more) course program, because C++ has changed a lot in the past 20 years (including 4 revisions of the standard).
