Everyone has their own sector of working freely. I would like to go with C++ because it's the basic of programming.
		
		
	 
That is a very naive and silly thing to say.
The first version of 
BASIC was released on 1 May 1964 developed by John George Kemeny, the Dartmouth College Mathematics Department chairman and his colleague Thomas Eugene Kurtz. Basic itself was based up 
FORTRAN that was released in 1957 and 
FORTRAN II (released in 1958). If you have never heard of 
FORTRAN consider this from Wikipedia "Since August 2021 
FORTRAN has ranked among the top 15 languages in the TIOBE index, a measure of the popularity of programming languages". The last stable release of 
FORTRAN was in 2018.
Microsoft's first product was 
Altair Basic released on the 1 July 1974. It is the forerunner to 
Visual Basic (released in 1991) and 
VB.Net (released in 2002). 
VB.Net is the reason this forum exists.
C++ was first released in 1985. 
C++ was in itself based upon 
C (released in 1972) and 
C was based upon the 
B programming language (released in 1969). 
B was developed from 
BCPL (released in 1967). 
C# (released 2002) is simplistically stated 
C++ for Microsoft Windows.
There is also a 
D programming language amongst others, too many to name. [
Ada (1980) is my favorite name for a programming language named after Ada Lovelace a computing pioneer. My next favorite name is 
Linda (1986) a "coordination programming language" named after Linda Lovelace who after a memorable film career campaigned for women's rights.]
As a programmer, if you have learnt one programming language you can read many others. As an example 
C#  and 
VB.Net share the same namespaces, a competent VB.Net programmer can convert 
C# examples to 
VB.Net without learning 
C#. There are commonalities across all computing languages.
May I suggest you read some of the Wikipedia articles on programming languages and their history. 
BCPL, 
FORTRAN, 
BASIC, 
C, 
COBOL and follow the links to the other languages that came later.
It is also worth reading about Ada Lovelace who in 1873 had her algorithm, the first ever specifically tailored for implementation on a computer was published. For this Ada Lovelace is often been cited as the first ever computer programmer.
