WebJun 24, 2024 · The sizeof operator is the most common operator in C. It is a compile-time unary operator and used to compute the size of its operand. It returns the size of a variable. It can be applied to any data type, float type, pointer type variables. WebFeb 26, 2009 · A C++ (or C) implementation can define the size of a type in bytes sizeof (type) to any value, as long as the expression sizeof (type) * CHAR_BIT evaluates to a number of bits high enough to contain required ranges, and the ordering of type is still valid (e.g. sizeof (int) <= sizeof (long) ). Putting this all together, we are guaranteed that:
