Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

== Why is this an issue?
|
|
|
|
``++<stdlib.h>++``'s ``++atof++``, ``++atoi++``, and ``++atol++`` functions, which convert strings to numbers, have undefined behavior when the strings cannot be converted, and should therefore be avoided.

|
|
|
|
=== Noncompliant code example
|
|
|
|
[source,cpp]
|
|
----
|
|
int converter (const char * numstr) {
|
|
return atoi(numstr); // Noncompliant
|
|
}
|
|
----
|
|
|

|
|
=== Compliant solution
|
|
|
|
[source,cpp]
|
|
----
|
|
int converter (const char * numstr) {
|
|
return strtol(numstr, NULL, 10);
|
|
}
