6. cpp #include #include int main() { using namespace std; const char* charstr = "this is one very long string " "so I will continue it on the next line"; string str = charstr; <-- 1 cout << str << endl; cout << "\nA\tb\\c\'d\"" << endl; return 0; } 36 Part I: Introduction to C++ and Qt 4 Part I: Introduction to C++ and Qt 4 37 (1)STL strings can hold onto C-style char* strings. out The output should look something like this: this is one very long string so I will continue it on the next line A b\c'd" Notice that this program shows a way to avoid very long lines when dealing with string literals.

Another reference that provides maximum content and minimal bulk is [Fowler04]. 1 is a class diagram with only one class: Person. Notice that the declarations appear in the name : type, Pascal-style, rather than the more familiar C++/Java style, where the names come after the types. This is to help with readabilitybecause we tend to read from left to right, this syntax helps us find names faster. Notice also that public members are preceded by a plus sign (+) and private members are preceded by a minus sign (-).

The expression (boolExpr) ? expr1 : expr2 returns expr1 if boolExpr is true, otherwise it returns expr2. 13 shows the output that this program produces. 13. cpp [ . . 6831 k % j = 2 k = 7 k = 8 k = 8 Exercises: C++ Simple Types 1. Here is an old favorite: Write a short program that asks the user to choose Celsius-to-Fahrenheit or Fahrenheit-to-Celsius. Then ask for a lower bound, an upper bound, and an increment. Using that information, produce an appropiate table with column headings. The main() part of your program should be relatively short.
