When I first compiled the arm program, I encountered this error. I searched the internet for information and found a solution for this error message, as shown below:
If the error message: the session file 'C: \ User \ USERNAME \ default-1-2-0-0.ses 'could not be loaded ., it indicates that your project file name (and file path) contains some Chinese characters.

The functions implemented by the component (all functions, from initialization to state update, etc.) and the exposed interfaces (accessors or custom methods, etc.) have some proportional relationships.These components are almost always implemented with fewer operations (this is not an interface operation, but an

During the execution of the above code, the compiler implements the memory space diagram as follows:Look at the leftmost column first. MyObject is an object pointer to a 0 offset (virtual method table pointer) in the object's data space. You can see that MYINTF/MYINTFA/MYINTFB three interfaces are implemented as pointers, and these three pointers point to an area of 4 bytes in MyObject object data space, r
