Sample Checked C code

This directory contains some sample Checked C code:

• hello-world.c: The canonical "hello, world" program, using Checked C. Show how to declare bounds for the array of arguments.
• echo-args.c: Echo arguments to the output console. Use the array of arguments with bounds.
• echo-args-buggy.c: A buggy version of echo-args.c with an off-by-one error that tries to read past the end of the array of arguments.
• find-pattern.c: The "find pattern" program from Kernighan and Richie, rewritten to use Checked C. This program illustrates some subtle points about using strings in Checked C.
• string-helper.c: A short tutorial on using strings in Checked C, with Checked C versions of atoi, squeeze, strcmp, strlen, and reverse.

• avoid-warning.c: This example shows how to use dynamic_bounds_cast to avoid a compile-time warning that the compiler cannot prove declared bounds are valid.

• spec: Examples drawn from the Checked C specification.
