sprintf function is also very strong is to write the data into the string not much to repeat

Sstream is C + + only.

Flow processing is also very powerful

But since I'm not ready to continue learning C + +,

It's a waste of time to find work.

The next period of time mainly focus on the algorithm

Start learning Java and Python
