Pointer Operators
Explore the use of pointer operators & (address-of) and * (indirection) in C programming. Understand their application with variables, constants, and expressions, common errors to avoid, and safe usage to manage memory addresses effectively.
& and * are both known as pointer operators. Let’s see the use of pointer operators with a variable, a constant, or an expression.
& with a variable, a constant, and an expression
& is called the address-of operator. & can only be used with a variable, as a variable is allocated space in memory. Whereas, the compiler does not reserve any space for a ...
