CLASS 8 - More Operators

 

In Chapter 6, "Manipulating Data with Operators," you learned about some important operators in C, such as the arithmetic assignment operators, the unary minus operator, the increment and decrement operators, and the relational operators. In this lesson you'll learn about more operators, including

    The sizeof operator
    Logical operators
    Bit-manipulation operators
    The conditional operator

 

 

Summary

In this lesson you've learned the following:

  •     The sizeof operator returns the number of bytes that a specified data type can have. You can use the operator to measure the size of a data type on your machine.
  •     The logical AND operator (&&) returns 1 only if both its two operands (that is, expressions) are TRUE. Otherwise, the operator returns 0.
  •     The logical OR operator (||) returns 0 only if both its two operands are FALSE. Otherwise, the operator returns 1.
  •     The logical negation operator (!) reverses the logical value of its operand.
  •     There are six bit-manipulation operators: the bitwise AND operator (&), the bitwise OR operator (|), the bitwise XOR operator (^), the bitwise complement operator (~), the right-shift operator (>>), and the left-shift operator (<<).
  •     The conditional operator (?:) is the only operator in C that can take three operands.

Using Shift Operators

There are two shift operators in C. The >> operator shifts the bits of an operand to the right; the << operator shifts the bits to the left.
