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
Assume that i = 1, j = 2, k = 3 and m = 2. What does each of the following statements print?
``` a) cout << (i == 1) << endl; b) cout << (j == 3) << endl; c) cout << (i >= 1 && j < 4) << endl; d) cout << (m <= 99 && k < m) << endl; e) cout << (j >= i || k == m) << endl; f) cout << (k + m < j || 3 - j >= k) << endl; g) cout << (!m ) << endl; h) cout << (!(j - m)) << endl; i) cout << (!(k > m)) << endl; ```
