Example text

4. Application software is far shorter, the object construct organizes the properties and functions of a physical object into a single self-contained unit that is easily modified and transferred between programs. Object-oriented languages additionally provide a foundation for still higher-level programming idioms such as graphical programming, for which right-clicking on a calculator icon reveals a list of its attributes, which in this case could be the value, calculatorValue, held in the calculator’s internal memory register and the inputValue( ), depressSineButton( ) and displayValue( ) functions.

10 break, continue and exit( ) int loop = 0; while ( loop < 5 ) { cout << loop++ << '' ''; } or alternatively with a do . . while statement as int loop = 0; do { cout << loop++ << '' ''; } while ( loop < 5 ); Note that a terminating semicolon is required for a do . . while statement but not for the while statement. However, if int loop = 6; is substituted for int loop = 0; above, only the while statement reproduces the results of the for loop since the logical condition in the do . . while construct is evaluated after rather than before the statement block is executed.

2 The main( ) function The entry point into (the first code executed by) a C++ program is the body of the main( ) function. Accordingly, every C++ program must contain a single occurrence of int main( int argc, char *argv[ ] ) { ... statements ... } or, more simply, main( ) { ... statements ... } which can appear anywhere in the source file (program) after the external constructs appearing in main( ) are declared. In the first of the two above implementations, return 0; or, equivalently in DEV-C++, return EXIT_SUCCESS; (the global constant EXIT_SUCCESS equals zero) should preferably immediately precede the closing brace.
