This little program makes two calls to the overloaded insertion operator, two calls to the overloaded extraction operator, and two calls to the standard (predefined) extraction operator. The first call is operator>> (tin, sl) which passes areference to the istream object tin to theparameter istr and a reference to the string object s 1 to the parameter s. Then I He1 lo, I is read into the C-string temp. This is assigned to the String object sl, and then a reference to c in is returned. That return value is then used in the second call opera tar>> ( c in, s2 ) which works the same way, leaving the object s 2 representing I War 1 d ! I . ' The output line intermingles the two calls to the overloaded << operator with the two calls to the standard << operator in the cascade:

f( f( f( f( tout, sl ), ~****" ), s2 ), end1 );

left. The left associativity of the output operator CC involved that have the same precedence level.

Increment and decrement operators abbreviate certain kinds of assignments. C++ also allows the assignment to be combined with other operators. The general syntax for these combined assignments is

Test Case 3,4,5 3,4,8 0,5,6 5,8,5 3,8,3 0,4,0 3,3,3 0,0,0

variable n += 8;

n=n+8;

This shows how to use some of the combined oDerators:

#include ciostream.h> // Tests combined operators: main0 -C int n = 44;

Output Scalene Not a triangle Bad inputs Isosceles Not a triangle Bad inputs Equilateral Bad inputs

n +=9;

tout C-C n CC endl;

n II 5 ; -

tout CC n CC endl;

A multiple-condition testing criterion requires that each primitive relation condition is evaluated both true and false. Additionally, all combinations of T/F for the primitive relations in a condition must be tried. Note that lazy evaluation3 of expressions will eliminate some combinations. For example, in an and of two primitive relations, the second will not be evaluated if the rst one is false.

The statement n += 9 adds 9 to n, the statement n - = n *= 2 multiplies n by 2. 1.17 INTEGER OVERFLOW AND UNDERFLOW

In the pseudocode in Example 10.3, there are multiple conditions in each decision statement. Primitives that are not executed because of lazy evaluation are shown with an X .

Unlike the integers of pure mathematics, the integer objects in a computer are bounded. As we saw above, each integer type has a maximum value and a minimum value. If the value of a variable exceeds either of its bounds, we have what is called overflow.

EXAMPLE 1.21 Testing for Overflow This program shows what happens when an object of type short overflows:

A compiler does lazy evaluation when it does not generate code for tests that are not needed. For example, if the rst condition of an or expression is true, the second condition does not need to be tested.

#include ciostream.h> #include climits.h> // Tests for overflow for type short: main0 short n = SHRT -MAX - 1; tout CC n++ CC endl; tout CC n++ CC endl; tout CC n++ CC endl; tout CC n++ CC endl; return 0;

The values wrap around the endpoints of 32,767 and -32,768. In other words, the value that results when 1 is added to 32,767 is -32,768. This is obviously wrong!

Most computers handle overflow this way. The values wrap around, so that the number that comes after the maximum value is the minimum value. This is the worst kind of error that can occur on a computer because normally there is no outside evidence that anything has gone wrong. As we shall see later, C++ fortunately provides mechanisms to help the programmer handle this problem. Overflow is one kind of a run-time error. Another common example is division by zero. But this is not as great a problem because you will know when it happens: the program crashes! Numeric overflow is like an internal hemorrhage: you may not be aware that you are in grave danger.

In C++, the character type char is one of the integer types. This means that any variable of type char may be used in integer expressions just like any other integer. For example, the integer arithmetic operators apply to char variables:
