Terms 23: Consider using other libraries
When we quote the library, there are often two kinds, C . For example, stdio.h and iostream are STDIO.H and IOSTREAM. In general, C is more efficient, while C achieves more secure. How should this? There is no certain principle, there is no absolute. It is necessary to see this problem from a product point of view, the only affirmation is that these two libraries need to be understood.
