C sizeof struct element

WebIf an unsized array is the last element of a structure, the sizeof operator returns the size of the structure without the array. The sizeof operator is often used to calculate the number of elements in an array using an expression of the form: sizeof array / sizeof array[0] See also. Expressions with Unary Operators Keywords Websizeof is a unary operator in the programming languages C and C++.It generates the storage size of an expression or a data type, measured in the number of char-sized units.Consequently, the construct sizeof (char) is guaranteed to be 1.The actual number of bits of type char is specified by the preprocessor macro CHAR_BIT, defined in the …
