12. C/C++ memory access

• Our previous example needs an important modification to compile properly using today's C/C++ compiler:

  
      int MEMORY = 0;                       // start at the beginning of memory
  
      int location = 248;                   // set location of memory cell #248
  
      MEMORY[ (char*) location ] = 65;      // save character A in memory
  
      char x = MEMORY[ (char*) location ];  // assign value from memory to character x
  
  

• The expression

  
      (char*) location
  
  

  tells the compiler that we are accessing a specific data type -- a char in our example.
