13. What is a local variable?

• Any memory declared inside a function is called a local variable::

  
      void f()
      {
          int count = 0;
      }
  
  

• Let's try an example:

  
      #include <cstdio>
  
      int main()
      {
          int x = 4;  
          printf( "x is stored at %p\n", &x );
          return 0;
      }
