WebTherefore i is a pointer to int. Variable declarations in C use type expressions, int and * are just operators. int *i parses as int (* (i)) and is interpreted as i has type pointer-to integer. char *p [] parses as char (* ( [] (p))) (because [] has higher precedence than *) and means: p has type array-of pointer-to char. – Giorgio WebDec 30, 2011 · In C-like languages, whitespace mostly doesn't matter. All versions you listed parse as the same three tokens: int & b so they mean the same to the compiler.
