Quiz on float datatype and sizeof keyword.
Floating-point numbers Floating-point numbers are a type of data that can represent real numbers. They are stored in memory using a format that includes a sign bit, an exponent, and a significand. The size of a floating-point number depends on the specific implementation of the C programming language. However, it is typically 32 bits or 64 bits. Floating-point numbers can be used to represent a wide range of values, from very small numbers to very large numbers. However, they are not as precise as integers.
Sizeof operator The sizeof operator is a unary operator that returns the size of its operand, in bytes. The sizeof operator can be used with any data type, including floating-point numbers. The result of the sizeof operator is an unsigned integral value.
