What is the output of this program?
#include <iostream>
using namespace std;
class rect
{
int x, y;
public:
void val (int, int);
int area ()
{
return (x * y);
}
};
void rect::val (int a, int b)
{
x = a;
y = b;
}
int main ()
{
rect rect;
rect.val (3, 4);

C++ question #include <iostream> using namespace std; void printReverse(int); int main() { int number = 12345; cout << "Original : " << number << endl; cout << "Reversed : "; printReverse(number); } void printReverse(int x) { if (x == 0) return; cout << x % 10; printReverse(x /= 10); } Modify the above recursive program to output the number in the same order. Note that the program still should break up the number and then output it in the...
