that the activity records of each method (that is, local or automatic variables) are allocated on the stack, which not only stores these variables, but also can be used to nest methods of tracing. As we observe, we can see that the method is called as follows:1, calculation parameters, parameter transfer2, the return address of the Save method3, control transfer to callee4, save the necessary caller on sit
