The function of the keyword sizeof is to return the number of bytes of memory consumed by the object or type, and the return value is size_t.Number of bytes consumed by the base data type: (32-bit system)Char 1 bytesBOOL 1 bytesShort 2 bytesint 4

typedef this keyword is used to give a new name to a type, unlike define, a typedef gives a symbolic name that is limited to a type, not a value. Here is an example:typedef short WCHAR;typedef defines the short type as WCHAR type, then encounters

The data in the actual problem often has different types of data types, such as students in school, age (int), height (float type), weight (float type), name (string type), gender (char), and so on, which are the attributes that each student should

In C + +, subscript operations do not add elements, and for any use of subscript operations, such as string types, vector types, and so on, must be existing elements to be indexed with subscript operators. If the type is empty, passWhen the
