Hello...

In Btech..you have to study all the languaues either it may be python or may by be java or c++...

But difference is that ...that you will going to study all the languages in different different  semester....

Ans in 1st year you will learn about the C language only..and some basics of the programing..

In 2nd you will learn about the C++  and loke this way  you will the languages one by one..

Hope you are clear to your question..

Good luck...
