Place the pointer or reference indicator next to the type name. Don't put it next to the variable name or place it with a space on either side. In other words, do this:
char* foo;
int& theInt;And not this:
char *foo;
int &theInt;Only declare a single variable on any line. Combining this rule with the last one will prevent you from writing something like this:
int* varOne, varTwo;If you were to write this, you would have declared one pointer and one integer variable, when in fact you meant to declare two pointers.
