Answer Posted / suman halder
within printf statement,f(2+2) i.e f(4) must return a value so that this value could get printed through %d format specifier..
Now,as f(x) is a macro template and macro expansion code for this template is not specified..so,here the situation is like,we are trying to return an integer value from a function which is having a "void" return type..
so,compiler flashes "Expression syntax error"..as during preprocessing macro template can't be replaced by macro expansion...
