Did you know that a blank line can cause syntax errors?
The number of blank lines that I have been responsible for maintaining is an estimate based on
summary figures for projects I have worked on since the mid 90's
In 4 projects, written in C, the total lines of code and total blank lines are:
Project,Total lines,Blank lines,Comments
An example of a blank line causing a syntax error is:
void main( void )
#define blankmac \
int a = 1 \
So you can imagine how many potential bugs there are in these projects given that on average there's one every 1,000 lines!
