Could I retrieve the datatype from a variable in C?

Question

Has a way to get the datatype in C?

For example:

int foo;

if (foo is int)
{
    // do something
}

or something like:

if (typeof(foo         


        

Answer 1

This is called type introspection or reflection and is not supported by the C language. You would probably have to write your own reflection library, and it would be a significant effort.
