This programming language may be used to instruct a computer to perform a task.
|Execution method:||Compiled (machine code)|
|Parameter passing methods:||By value|
If you know C1R, please write code for some of the tasks not implemented in C1R.
C1R is a general-purpose, procedural, imperative computer programming language, partially developed by André van Delft in 2011. It is a small extension to the well known C programming language, allowing for very small programs that implement tasks that are implemented by C programs at RosettaCode.org.
C1R can also be regarded as an adaptive language, as the set of valid C1R programs varies with the C implementations for tasks at Rosetta Code.
The development of C1R has been inspired on the HQ9+ and C0H programming languages. HQ9+ accepts "H" in its source to print "Hello World!". C0H improves over HQ9+ by offering the full power of the C language; moreover, C0H offers a shorter path to writing a Hello World program: just create an empty file. C1R allows the user to submit a text file with just a simple reference of a task implemented in C at Rosetta Code; that reference is the implementation of the task in C1R. E.g., the following C1R program
does exactly the same as the C program listed at the "Hello_world/Text" page, namely print "Goodbye world!".
C1R is implemented using a Shell script that calls the C compiler. The script starts by testing whether C code should be downloaded from the Rosetta Code site. The Quine task is treated as a special case. See C1R Implementation
When hearing of C0H, Jelle van Zeijl suggested to make a similar language based on downloading C code from the Rosetta Code site.
To get a reference document on C1R, it is advised to upgrade a reference document on the "C" programming language, and attach a Post-it note stating C1R is like C, except that in case it contains just 1 line that directs to a Rosetta Code URL with a valid C implementation.
