Is there a C++ shell?

No, there isn’t. Unlike Python, C++ is a compiled language.

Can C code be compiled as C++?

Due to this, development tools for the two languages (such as IDEs and compilers) are often integrated into a single product, with the programmer able to specify C or C++ as their source language. However, C is not a subset of C++, and nontrivial C programs will not compile as C++ code without modification.

Can we convert C++ code to Python?

Nope, it completely and utterly impossible. Once a program is written in C++ it can never be written in python ever….

Can you mix C++ and Python?

There are two basic models for combining C++ and Python: Extending, in which the end-user launches the Python interpreter executable and imports Python extension modules written in C++. It’s like taking a library written in C++ and giving it a Python interface so Python programmers can use it.

Just declare the C++ function extern “C” (in your C++ code) and call it (from your C or C++ code). For example: // C++ code: extern “C” void f(int);…Now the f() functions can be used like this:

  1. /* C code: */
  2. void f_i(int);
  3. void f_d(double);
  4. void cccc(int i,double d)
  5. {
  6. f_i(i);
  7. f_d(d);
  8. /* */

How do you change C to Python?

It is essentially impossible to convert C code into Python. But it is easy to do the opposite, where you convert Python in to C code.
