Describe the unit of measure for font size and paragraph spacing

The following program has been partitioned into two files. Before we commented out the keyword namespace and the curly braces that were around func(int) this program compiled and had this output:

``` func(5) = 25 junk(5) = 75 ``` Will the code compile now? If so, predict the output and explain. ``` // This goes in file A.cpp //namespace // //{ int func(int i) { return i*3; } //} int junk (int i) { return i*func(i); } // This goes in file B.cpp #include int func(int i) { return i*5; } int junk(int i); //from A.cpp int main() { cout <<”func(5) = “ << func(5) << endl; cout <<”junk(5) = “ << junk(5) << endl; ``` What will be an ideal response?

In a C++ program, statements that begin with the symbol # are called ____________________ directives.
