TLOC : Total Line of Code
LOC : Line of Code. Counting code lines which include statement
CLOC : Comment Line of Code. Counting code lines which includes comment
BLOC : Blank Line of Code. Counting blank lines


For TLOC, Comment Line of Code and Line of Code can be duplicated. For example, if your one source code line includes statement and comment together, CLOC and LOC are counted at the same time. 
Total Line of Code is just counting all lines of one source file. Therefore, TLOC can be smaller than sum of LOC and CLOC.
