Clarification on rule 10.6

[anuj1085]

Is the rule only applies to "u" suffix or this rule also applies to "UL", "L" and other suffixes

[misra-c]

This rule only applies to integer constants for which the standard C type without a suffix is an unsigned type. For example 0x8000 is of type unsigned int in a 16-bit environment. Rule 10.6 requires you to add a "U" suffix in this case.

The rule does not require you to add other suffices, for example the "L" suffix to those constants which have a long C type.

More details on the background to this rule can be read in the MISRA C:2012 documentation for rule 7.2.
