variables are stored in the stack4. Finally, when exiting the function, restore the register environment of the calling functionCode writingThe initialization of the stack is to specify the location of the SP pointer, and the SP pointer position is specified based on the maximum memory address. When the stack is used, the position is decremented from its maximum position. For example, 2440 SP pointer position is 0x30000000+400000 (64M) =0x34000000/***********************************************

Topic linksTest instructions: The definition of the self-guarding number: If the number of squares of a number equals this number, then it is called the number of self-shou number. For example 5*5=25, 5 is the self-guarding number. Let you ask for no more than n-bit self-hold numberIdea: In fact, the number of self-guarding has two properties: by multiplying the number of the latter by two, the number of the product is still the self-guarding. Just n bit of self-shou number must be two, of cours
