I started my industry experience in 2007 as internship in testing using
C/C++ for half a year. then had 2.5 years industry developer experience in
C/C++ in financial area.
what do you guys think the expected level should be? what is the average
level for a 3.5 yrs C/C++ developer? what about above average level? |

returning from function swap.
logically the code is fine. i didn't find any problems. |

the following example...

发帖数: 121 | 7 My 2 cents: you should be familiar with basic C++ concepts and designs. More
importantly, you should have delivered a few projects in production systems
. You should be familliar with the whole software development process, as
well as the domain knowledge (finance in this case) that are relevant.

一个是这个
一个是汉诺塔
所谓的省掉了一个中间变量
其实是你小看了编译器的优化能力

发帖数: 10158 | 13 我比较hate C++
一方面加了不少东西，号称灵活方便，但是另外一方面，加的这些东西trick奇多，极
其复杂，给程序调试带来很大的困难，而且代码看上去极其难看
面试C++程序员更是成了茴香豆几种写法的现代版

void swap ( int& a, int& b )
{
int temp = b;
b = a;

any problem?
