Character Array Concatenation An important feature of the C preprocessor is character array concatenation. This feature is used in some of the examples in this book. If two quoted character arrays are adjacent, and no punctuation is between them, the compiler will paste the character arrays together into a single character array. This is particularly useful when code listings have width restrictions, as in Listing 2-4. Listing 2-4. \n"; } ///:~ At first, the code in Listing 2-4 can look like an error because there’s no familiar semicolon at the end of each line.

Training The first step is some form of education. Remember the company’s investment in plain C code, and try not to throw everything into disarray for six to nine months while everyone puzzles over how multiple inheritance works. Pick a small group for indoctrination, preferably one composed of people who are curious, work well together, and can function as their own support network while they’re learning C++. An alternative approach that is sometimes suggested is the education of all company levels at once, including overview courses for strategic managers as well as design and programming courses for project builders.

Listing 2-6. cpp // Call another program #include // Declare "system()" using namespace std; 39 Chapter 2 ■ Making and Using Objects int main() { system("Hello"); } ///:~ To use the system( ) function, you give it a character array that you would normally type at the operating system command prompt. This can also include command-line arguments, and the character array can be one that you fabricate at runtime (instead of just using a static character array as shown in Listing 2-6). The command executes and control returns to the program.
