The symbolic toolbox cannot be compiled or code generated at all.
You need to split your program into two parts. One part uses uncompiled MATLAB and user input and the symbolic toolbox to arrive at a particular formula. Then it uses matlabFunction to write the formula to a file as .m code that does not use symbolics at all.
Then the second part of your project would be code that accepted user interaction etc. and called upon the above mentioned nonsymbolic code. This part could be compiled or code generated.
Note that this requires a distinct compilation or code generation for each different formula created by the first part of the project.

I am trying to convert this simple code into excutable using matlab coder.
function y = hello_world
%#codegen
y = 'Hello World!';
converting to source code C works but when i change the build type to Executable
It gives me this error: Build error: C compiler produced errors. See the Build Log for further details.
