Example text

Each die has six faces, which are numbered 1 through 6. A throw results in a number that is the total of the two top faces. The first throw establishes the player's number. If that number is 7 or 11, the player automatically wins. If that number is 2, the player automatically loses. Otherwise, the player continues throwing until she wins (by matching her number) or loses (by throwing a 7 or an 11). 4. Write a program that accepts two values from the user (customer): the total purchase amount and the amount submitted for payment.

2. Operators new and delete C++ has a mechanism that permits storage to be allocated dynamically at runtime. This means that the programmer does not need to anticipate the memory needs of a program in advance and make allowances for the maximum amount of memory that might be needed by the program. Dynamic allocation of storage at runtime is a powerful tool that helps to build programs that are efficient and flexible. Thenew operator allocates storage from the memory heap (also called the heap, free pool, or free storage) and returns a pointer to the newly allocated object.

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. They can be broken at any white space character and are concatenated automatically using this syntax. 6 so that, with a single output statement, the output becomes: 1. GNU stands for "GNU's Not Unix". 2. 8. ) In addition, C and C++ both provide a name that signifies the absence of type information (void).
