How many lines-of-code does a developer write (life time)?

[CPallini]

That would make my code a colossal collection of comments. :laugh:

Are we talking "lines of code" or "original lines of code"?

Original? As you said, there's no original code now. Just the stuff we keep copying and pasting. I think all the copying started back in K&R C and then Petzold Programming Windows. After that, once it got onto the Internet it's all just copy code. All code can be directly traced back to those two sources. :laugh:

I've heard that about thirty years back (when C was more dominant), some managers used to have tools to count the number of semicolons, each semicolon signifying a line as productivity tools. So, some developers used to have lines as ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; which is as many lines of code.

let's see. I've written about 10,000 lines this week (strangely enough, I've been counting, and working on a single project so it's easy) gosh. im my life? I've been coding for about 32 years I type faster these days, and have a lot of time to do it these days. and I can crank out what, 520,000 lines a year if I apply myself. *32 years = 16,640,000 lines of code. we'll halve it. 8,320,000 so far. i've probably got another 10 million in me.

When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

for loops counts as 3 lines. glad i barely use linq. LOL

i've got a whole routine i cut and pasted from stackoverflow in my project. (it just prints an ascii tree of some data, but still THE SHAME!)

120,325,116 lines of code....no less, no more. duh. easy question, next?! :-D

Reacher said nothing. He could tell from the grease stain on the safety-catch that the Glock XP3-15 had been fired three times, yet he had only heard two shots. The smell from the muzzle indicated that the first shot had been fired 42 minutes and 17 seconds prior to the first. Given that the truck had been heading east at an average of 45 MPH, he knew for sure that this was the weapon that had killed Jackson in the warehouse in Topeka, the gun being held at an angle of about 15.6 degrees so that the shell would have severed Jackson's cerebral cortex instantly. The FBI forensic team duly resigned as they felt so crushingly unnecessary ... (I actually really liked the couple of Reacher books I read, but how many do we actually need?)

The goal of every APL programmer is to write the program on a single line. With APL, it is somewhat more realistic than in most other languages, like "The game of life" (from the Wikipedia article on APL): life←{↑1 ⍵∨.∧3 4=+/,¯1 0 1∘.⊖¯1 0 1∘.⌽⊂⍵} Thirty years ago, I did a little APL programming - but please don't ask me to explain this program. Give me at least three months to decipher it!

[kmoorevs]

I'm finding that as the years go by, I'm writing less and less new code. That is to say, I encounter fewer situations that I haven't already dealt with. Being lazy, this leads to either copy/pasta and probably some customization, or better the creation of a reusable utility function. Also, the IDEs, particularly intellisense are so much better these days than when I started...this code was generated by a tool. :laugh: That said, a rough estimate would be around 1.8M in 20 years, around 90K/year average, but as stated, the majority would have been written in the first half of that time frame.

When the VAX supermini was every programmer's dream, DEC published statistics showing that the average production volume for those developers writing the microcode for the 780 (the firs one in the VAX series) was 250 (micro)instructions a year. Everybody knows that you do not leave microcode writing to the novices - those programmers were among the very best that DEC had. Yet it took them, on the average, a full day's work to figure out a single instruction. Since the 780 was the first crop, I guess lots of the effort went into competence building, learning the tools etc. Maybe it even included some tool development. I don't know how DEC did the counting, only that the total number of microcode instructions produced divided by the number of microcode programmers returned about 250 instructions/year per programmer.

"Lines of code" is a rather meaningless metric, since you can rewrite a line many, many times. And what constitutes a "rewrite of a line" anyway, if a single line then gets broken down into multiple lines (or vice-versa) after some refactoring?

Now there's a feat, cut and pasting from a cereal packet. I understand the quality may reflect that as a source but getting the cardboard into into the computer via the screen would be a real trick.

Nah, all you have to do is glue it to the scroll bar so it moves up and down with the rest of the code. Pritt Stick will do it if you smear it on the pixels carefully and use a big enough monitor. Boeing use this all the time for their flight control software.
