Question

After learning good amount of c++, i’m now into STL containers and algorithms template library, my major concerns are,

1) Is this library same across different platforms like MS, linux n other os?

2) will quality or efficiency of program c++ module decrease with more use of STL containers and algorithms, i think i can’t customize it to all needs.

3) Is this template library good to use in linux system programming, kernel modules?

4) lastly can i use this in programming contests, because it relives a lot of coding and pressure off shoulders.

Answer 1

1) Is this library same across different platforms like MS, linux n other os?

No. Except the standardized interface, the implementations are all different for each compiler suite, and sometimes they also provide custom extensions such as hash_map.

2) will quality or efficiency of program c++ module decrease with more use of STL containers and algorithms, i think i can’t customize it to all needs.

I don’t think so. The quality and efficiency should be much better than cooking one up by your own, unless you have very special needs.

3) Is this template library good to use in linux system programming, kernel modules?

Better use C for the kernel.

4) lastly can i use this in programming contests, because it relives a lot of coding and pressure off shoulders.

Depends on the rules of the contests.
