Recommendations are identified by the label recommendation. The CERT C++ Coding Standard does not currently expose any recommendations; all C++ recommendations have been temporarily removed.
Noncompliant Code Examples and Compliant Solutions
Noncompliant code examples illustrate code that violates the guideline under discussion. It is important to note that these are only examples, and eliminating all occurrences of the example does not necessarily mean that the code being analyzed is now compliant with the guideline.
Noncompliant code examples are typically followed by compliant solutions, which show how the noncompliant code example can be recoded in a secure, compliant manner. Except where noted, noncompliant code examples should contain violations only of the guideline under discussion. Compliant solutions should comply with all of the secure coding rules but may on occasion fail to comply with a recommendation.
Exceptions
Any rule or recommendation may specify a small set of exceptions detailing the circumstances under which the guideline is not necessary to ensure the safety, reliability, or security of software. Exceptions are informative only and are not required to be followed.
Identifiers
Each rule and recommendation is given a unique identifier. These identifiers consist of three parts:
- a three-letter prefix that represents the topic the rule/recommendation belongs to
- a two-digit numeric value in the range of 00-99
- a suffix that represents the associated language or platform
Numeric values in the range of 00-49 are reserved for recommendations, while values in the range of 50-99 are reserved for rules. (The values used for C are different. It uses 00-29 for recommendations and 30-99 for rules.)
Supported Languages and Platforms
See the table below for a summary of supported languages and platforms:
Suffix | Language/Platform |
-C | C |
-CPP | C++ |
-J | Java |
-PL | Perl |
Examples
Here are some example identifiers with an explanation of each:
INT50-CPP Do not cast to an out-of-range enumeration value
This identifier indicates a recommendation
“INT” stands for the Integer category
“50” is the unique identifier
“-CPP” stands for the C++ language
EXP00-J Do not ignore values returned by methods
This identifier indicates a rule
“EXP” stands for the Expressions category
“00” is the unique identifier
“-J” stands for the Java language
FLP00-C. Understand the limitations of floating-point numbers
This identifier indicates a recommendation
“FLP” stands for the Floating Point category
“00” is the unique identifier
“-C” stands for the C programming language
