C is best thing since sliced bread.
When it comes to optimisation, u need it in C or in assembly or in life generaly.
optimization is second best thing since sliced bread :)
Assembly is third best ... but ...

Whatever your knowledge is you always need other thoughuts and ideas, dont be confused I ask questions for the following reasons :
1. To increase my knowledge
2. So that other people get the benifit also
3. Need to get the experience out of expert people which lots of the question asked dont satisfy me.
4. When i get a problem I like to ask for second opinion, it surely speeds up my problem solving. I always need people and i'm not complete expert.
5. This forum is great, to optimise it you need good questions and better answers.
Hope this clears up your confusion.
