C++ streams provide a unified interface for IO and data formatting! The two operators within the C-Aware IDE V.5 are the extraction operator and the insertion operator. The '>>' operator is used for formatted extractions while and the '<<' operator is used for formatted insertions. A flexible and simple way to design the input/output routines of any application is through the use of IO streams operators. Through this example the operators show the direction of data:
The beauty of these operators is that the x and y in the above examples can be any combination of function, RS232 serial stream, variable, string and more. Here are some quick and easy of examples of how you can use the C++ Stream Operators in your code:
- Use this example for a simple RS-232 output of a number:
cout << "Value is " << value << endl;
- For output to an LCD the following example code is just as simple:
lcd_putc << "Value is " << value << endl;
- Just as easily convert numbers to a string:
string1 << value;
- Or strings to a number:
string1 >> value;
- Parsing an input line of space delimited numbers is as easy as:
cin >> value1 >> value2 >> value3;
Of course integers, floats, int1's and more can be used just as easily as values.
- Many manipulators are available. For example to output the value in hex use this example:
cout << "Value is " << hex << value << endl;
