Thank you very much... <br />
I need to advance this so it would generate me a string to pass to other function!!<br />
<br />
So I mean <br />
string S<br />
S would be equal to <br />
(&quot;%s %s %d\n&quot;,__FILE__,__FUNCTION_<wbr />_,__LINE__<wbr />)

as part of my effort to understand an application I have, I need to build a macro that automatically builds a string with the file number and the line number. <br />
I can print that string that will show me the execution path.<br />
I am going to add this Macro in places and print the output!

In C++, I need a macro that builds a string that includes the file and the line number..

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
