Homework & Coursework Questions

I work 40 hours a week, I'm doing what I can. It's not like I can just pick it up, read the man pages, a few examples, and know how to do it. I've tried hundreds of permutations of these expressions and it's just not easy to do. I've read back on the thread dozens of times and I'm doing my best with what I'm given.

Temp.txt:

Code:

double square(double value) {  double c; c = value * value; return c; } double square2(double value2) { double c2; c2 = value2 * value2; return c; }

I have it finding all end curly braces and adding a new line.
Then I have it successfully finding the first function and proceeding with the replacement.
However, it doesn't find the second function. Can't seem to figure out why.

Code:

cat temp.txt |  sed -e "s/\}/}\n/g; s/\([a-zA-Z][0-9a-zA-Z]\+ \+[a-zA-Z][0-9a-zA-Z]\+(\)\([a-zA-Z][0-9a-zA-Z]\+\) \+\([a-zA-Z][0-9a-zA-Z]\+\)) *\({.*}\)/\1\3)\2 \3\; \4/"

double square(value)double value; {  double c; c = value * value; return c; }
 double square2(double value2) {  double c2; c2 = value2 * value2; return c2; }

sed 's/a/b/' only replaces the first match per line. 's/a/b/g' replaces all of them.

But if the lines are split on the first -e expression, there should only be one function per line when the second -e expression is matched, shouldn't it?
