The C++ compiler does something called as "name mangling"
for functions, while a C compiler does not. Name mangling
is a process wherein the name of the original function in a
c++ program gets changed to a new name via adding some
prefix and/or postfix to it.

As a result, a c program cannot find the required definition
when trying to link to a cpp object file.

This can be resolved by putting the following declaration in
a c++ header file that contains the cpp function declarations.
#ifdef __cplusplus
extern "C" {
#endif

// function declarations go here...
// ...

#ifdef __cplusplus
}
#endif

give me an example for testing a program showing the test path .show how the test is important and complex.
