## Variable Names
-Variable names in Go should be short rather than long. This is especially true for local variables with limited scope. Prefer c to lineCount. Prefer i to sliceIndex.
+Variable names in Go should be short rather than long. This is especially true for local variables with limited scope. Prefer `c` to `lineCount`. Prefer `i` to `sliceIndex`.
The basic rule: the further from its declaration that a name is used, the more descriptive the name must be. For a method receiver, one or two letters is sufficient. Common variables such as loop indices and readers can be a single letter (`i`, `r`). More unusual things and global variables need more descriptive names.
