This statement hits a nail squarely on its head.  I used to have
terrible problems with C syntax as I was learning C.  I then
discovered c-mode in GNU emacs.  Its basic trick is that it indents
the current line properly, depending on the lines before it.  I
commonly make the above errors, forget to close a quote or
parenthesis, and a myrid of other errors.  When I hit tab and the line
isn't adjusted to where I expect it to be, I know to take a look at
the previous couple of lines, and voila a typo is uncovered.

Another way to find this sort of error is to run your code through a c
beautifier (cb) and look at the way that it indents the code.  Of
course, you have to be suspecting this sort of error to even think
about attemptin this.
