sizeof(char)?
sizeof(int)?
sizeof(double)?
x in
class A { protected: static int x; };
double a, *b, **c; b = &a; c = & b; **c = 1.2;
void p(const int &x); p(3);
double that takes a value (of any
type) and returns that value added to itself without changing the
value. Write a fragment of code applying double to some
declared, initialize variable, where the type of the variable is in
namespace std.
names that is an
array of pointers to std::string values. Allow up to 20
names. Set the first name to your own name, but all of the rest should
be nullptr.
struct to create an array that is passed by
value.
void dosomething(int
nums[]); and write int s = sizeof(nums); in the
body. What does this set s to? Is there a way to change
the declaration of nums so s gets a different
value?
Circle with an x, y coordinate for the
center and a radius in centimeters. Include methods to return each
coordinate and the area. Write a class Disk which is derived
from Circle and adds a color (represented as an
integer). Add a method to return the color. All methods
of Circle should be public
in Disk as well.
Fraction that takes a numerator
and denominator, both of the same type, and has methods to return the
numerator and denominator as well as a method to_double that
returns the fraction as a double. For example
Fraction<short> x(3, 4);
cout << "x: " << x.numerator() << '/' << x.denominator << ", value " << x.to_double();
would print x: 3/4, value 0.75
auto x = a;
vs. x = b;.
while ( ! eof ) { read; process }
is a bad idea
doit
if doit reads files p and q
and generates r
strdup, a function which takes a null-terminated
tring and returns a fresh copy of the string. For example
char name[] = "Francis";
char *alt_name = strdup(name);
alt_name[4] = '\0';
printf("Full: %s, shortened: %s\n", name, alt_name);
would print "Full: Francis, shortened: Fran". Use malloc
and strcpy (and possibly other functions) in your answer.
