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.

Adding More Expressions into for

Adding More Expressions into for

The C language allows you to put more expressions into the three expression fields in the for statement. Expressions in a single expression field are separated by commas.

The Null Statement

Looping Under the for Statement

Looping Under the for Statement

The general form of the for statement is

for (expression1; expression2; expression3) { statement1; statement2; . . . }

Using Nested Loops

Using Nested Loops

You can put a loop inside another one to make nested loops. The computer will run the inner loop first before it resumes the looping for the outer loop.

Listing 7.7 is an example of how nested loops work.

The do-while Loop

The do-while Loop

You may note that in the for and while statements, the expressions are set at the top of the loop. However, in this section, you're going to see another statement used for looping,
