as that is more correct, added comments and helper methods, removed lines that
had no effect.
Behaviour unaltered.

Fix warnings from MSVC Code Analysis.

Bug [#2069]. LexerCPP: modernize int to std::string conversion

2018-12-11T21:38:19+00:00

* LexCPP.cxx (LexerCPP::EvaluateTokens): Use std::to_string to convert
  int to std::string.

Bug [#2069]. LexCPP: fix bug in arithmetic calculation by adding precedence levels

2018-12-11T21:38:19+00:00

The precedence for the implemented arithmetic operators +,-,%,*,/
is added, such that the calculations produce the correct results
honoring the standard precedence levels.

* Replace characterset setArithmeticOp by setAddOp and setMultOp.
* Replace precedence precArithmetic by precMult and precAdd
* (EvaluateTokens): Apply new precedences.

This fixes the bug in the arithmetic calculation:

// lines with 'false' should not be highlighted,
// those with 'true' should be.

#if 1 + 2 * 3 == 9
false
#endif

#if (1 + 2) * 3 == 9
true
#endif

#if 1 + 2 * 3 == 7
true
#endif

#if 1 == 5 % 2
true
#endif

#if 6 - 7 == -1
true
#endif

#if 25 / 5 * 5 == 25
true
#endif

#if 1 + 2 * 3 % 2 == 1
true
#endif

#if 1 + 2 * 3 % 2 == 2 + 1
false
#endif

Bug [#2062]. Interpret continued preprocessor lines correctly by reading all of

the logical line.

Bug [#2045]. LexCPP: Fix 'elif' token length

2018-09-23T23:24:10+00:00

Guard against shifting by negative amount as that is undefined behaviour.

2018-09-18T03:00:08+00:00

Use const and noexcept, initialize, avoid casts and improve variable name.

2018-06-04T04:45:28+00:00

Use lambda in preference to function object.
