question 20

Essay

The following program has been partitioned into two files.The command line command for compiling this is CC B.cpp A.cpp,where CC is the name for your command line compiler.For VC++ this is CL,for Borland,this is BCC32,and for the GNU C++ compiler,this is g++.If you use an IDE (integrated development environment)you would have to place both these files in your project then click the compile button.
Predict the output and explain your prediction.
// 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 <iostream>
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;
}
