Variable Scope in C++?

Question

In c++, any variables declared in main will be available throughout main right? I mean if the variables were declared in a try loop, will they would still be accessible througho

Answer 1

The scope of number is limited to the try block. Pull out this declaration to the main scope to access the variable after the try block:

int main()
{
   int number = 0;
   try 
   {
     // do something...
   }

   catch (...)
   {
     cout <<"Error";
   }

   number ++;
   cout <
