Code quality: Non meaningful identifiers

[s4rify]

Many names of variables and functions are chosen in a way, that it takes longer to recognize which tasks and contents they represent.
Example: A file name is stored in variables "temp" and "convertedValue". Other identifiers were "arr" and "arr2" and "i" and "i2".

Disadvantage 1: Understanding and changing the code causes more effort, because one has to go on "treasure hunt" again and again to trace back what is actually written into a variable.

Disadvantage 2: Risk of errors: Two not meaningful variables from the same type can be confused. Who knows what is in "i" and what is in "i2" if the variables were described at a remote code location?
