#include<iostream> using namespace std; void test(); int x = 0; // here one variable 'x' is created int main() { cout << x << endl; test(); cout << x << endl; } void test() { int x = 100; // here one variable 'x' is created cout << x << endl; for (int x = 0; x < 5; x++) { // here one variable 'x' is created cout << x << endl; } } // so, a total of 3 variables named 'x' are created.

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...
Consider the following C++ program: #include <iostream> using namespace std; void f1(int); void f2(int); void f3(int); int main() { f1(10); return 0; } void f1(int n) { f2(n + 5); } void f2(int n) { f3(n - 2); } void f3(int n) { cout << n << endl; // LINE 1 } Just before the program statement marked with the comment "LINE 1" is executed, how many stack frames will be on the program call stack?
