Variables

Variable names should be in mixed case, starting with lower case: linearity, credibleThreat, qualityOfLife
Large scope variables should have a meaningful name, short scope (e.g. counters) variables should have short names
Variable representing the number of a certain object should be given the prefix n (or m if matrix): nFiles, nSeeds,mRows
Adopt a convention on pluralization: either make all variable names singular or plural: don't create two variables that differ only by the final letter...
Variables representing the index/number associated with a single entity should be prefixed by i: iTable, iEmployee
Iterator variables should be prefixed by i,j,k, etc.
Avoid negated boolean variable names: avoid isNotFound; rather use ~isFound
Acronyms, even if normally uppercase, should be mixed or lower case isUsaSpecific rather than isUSASpecific
