./Playground/file0.c: In function 'main':
./Playground/file0.c:8:10: warning: assignment to 'int' from 'void *' makes integer from pointer without a cast [-Wint-conversion]
8 | sq_int = square(&x);
| ^
./Playground/file0.c: In function 'square':
./Playground/file0.c:18:9: warning: returning 'int' from a function with return type 'void *' makes pointer from integer without a cast [-Wint-conversion]

Answer 2

Please share your code.

Answer 3

I believe this is the sample code given in the C course under
"Strings & Function Pointers" -> "void Pointer" -> Page 2/3.

The sample code shown there is deeply flawed and would produce these warnings.

Answer 4

This is the given sample code.
