Extensions to the Language

These options support extensions to the C++ language.

-ext

Specifying -ext, enables the following HP aC++ extensions to the C++ standard:

64-bit integer data type support for:
- long long (signed 64-bit integer)
- unsigned long long (unsigned 64-bit integer)
Use this option to declare 64-bit integer literals and for input and output of 64-bit integers.
#assert, #unassert preprocessor directives, which allow you to set a predicate name or predicate name and token to be tested with a #if directive.

When this option is used with -AC89 or -AC99, it defines the following macros:

NOTE: When using -ext, specify it at both compile and link time. For example:

aCC -ext foo.C

compiles foo.C which contains a long long declaration.

#include <iostream.h>
 
void main(){
     long long ll = 1;
     cout << ll << endl;
}

The +e option is equivalent to the -ext option.
