     What is output by the following program?  #include   using std:: cout;  using std:: endl;  void f1():  int main()  {int x = 0;  cout  
  
  Solution
Answer:
Initially, x = 0
During call to f1, x = 3
At the end, x = 0
in main method and f1() method, we have \"x\" integer variable as local variable. so if we change the value of x in either of that methods that will not give impact on others. So im main method, we declared x variable value as 0 and not modified so x value will always be 0 in main method.
in f1() method, we declared x variable value as 3. so x value will be 3 in f1() method.
