NetId:
1. Consider this program:
#include <iostream>
using namespace std;
template <class a, int b> void func() {
cout << "this is func";
}
int main() {
long c = 5;
func<int, c> ();
}
(a) It will not compile because cis not an int.
(b) It will not compile because cis not a constant.
(c) It will not compile since main() doesn’t return an integer.
(d) It will compile and print “this is func” on the screen.
2. What is true about the following code:
#include <iostream>
using namespace std;
template <int b> void func() {
cout << "foo";
}
template <long d> void func() {
cout << "bar";
}
int main() {
const long c = 5;
func<c> ();
}
(a) It will not compile since two instances of func() have conflicting signatures.
(b) It will not compile since cis a constant.
(c) It will compile and print “foo” on the screen.
(d) It will compile and print “bar” on the screen.
3. Consider the following snippet of code:
1: int x = 5;
2: int * const y = &x;
3: int const * z = &x;
4: const int * t = &x;
5: *y = 6;
6: *z = 10;
7: *t = 11;
