- /*
- Program: Drystn (Dhrystone)
-
- Version: 1.00
- Date: September 25, 1987
-
- Language: ANSI C
-
- The following program contains statements of a high-level programming
- language (C) in a distribution considered representative:
-
- assignments 53%
- control statements 32%
- procedure, function calls 15%
-
- 100 statements are dynamically executed. The program is balanced with
- respect to the three aspects:
- - statement type
- - operand type (for simple data types)
- - operand access
- operand global, local, parameter, or constant.
-
- The combination of these three aspects is balanced only approximately.
-
- The program does not compute anything meaningfull, but it is
- syntactically and semantically correct.
