To respond to Jeff, the equivilent entire perl “script” would be:
#! /usr/bin/perl -p
…which I’m not sure if you’d count as zero lines of code (perl is infinitely better?;), but in general I’d agree with Ole probably 99% of applications I work with are in C or C++[1] … the last 1% are some form of quick automation script, and a very few are desktop apps. that are in C#/Java/Python … and with an average developer class workstation I can often still spot which are in the later category by their startup time, not to mention that something always goes wrong with them everytime their runtime changes (with Java being the worst, and python being the best … but there isn’t much in it).
[1] This is different if you talk about webapps. … but IME these are often written by morons who should be required to write them in ASM as revenge.
