4.2 Declarations

4.2.1 Alignment

Pointers and references are part of the type, and MUST be put near the type, not near the variable.

     const char* p;  // not `const char *p;'
     std::string& s; // not `std::string &s;'
     void* magic (); // not `void *magic();'

4.2.2 Declarations

• There MUST be only one declaration per line.

• Inner declarations (i.e. at the start of inner blocks) are RECOMMENDED. Variables SHOULD be declared close to their first use and their scope must be kept as small as possible.

• Variables SHOULD be initialized at the point of declarations.

  Hint: Your compiler can help you to detect uninitialized local variables.
