WebThe sizeof () operator is a function which returns the size of any data type, expression, array, etc. It takes the data type or expression as a part of argument which is mandatory and returns the result which is size of that data type in bytes. If it is an array it will return the number of elements present in it. WebThe float is one of the available data types in C++. This is used to store floating point numbers in variables. It’s a numeric literal – in the exponent or fractional form. For example, 10.5.

The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short, and long. The following table lists the permissible combinations in specifying a large set of storage size-specific declarations. The actual size of the integer types varies by implementation. The standard requires only size relations between the data types and minimum sizes for each data type: WebNotes. The types of these constants, other than CHAR_BIT and MB_LEN_MAX, are required to match the results of the integral promotions as applied to objects of the types …
