the caller's stack frame. Where our function is to get the value of the current stack frame EBP register, and the return address in the caller's stack frame, the input parameters passed to the current stack frame.So, according to the distribution of the data in the graph, we can know that the value of the register EBP is the highest address of the current stack frame, and that the memory unit that corresponds to the highest address is exactly the highest address of the caller's stack frame.The

}$$ have an Eigenvalue value of 4 with the corresponding eigenvectors of $[x]=\begin{bmatrix}-4.5\\ -4\\ 1\end{bmatrix}$ s the value of $[a]^{5}[x]$?Solution:Firstly, we show that $A ^{m}x=\lambda^{m}x$, where $\lambda$ are an eigenvalue of $[a]$. By mathematical induction, we can read off that $n =1$ are correct.\\ then suppose that $n =m-1$ are correct, that's,

. Unsigned u = 10; int I =-42; cout The first output should be needless to say. For the second output, first convert-42 to the unsigned number, and convert the negative number to the unsigned number, similar to directly assigning a negative value to the unsigned number, the result is equal to the negative number plus the unsigned number. Is there some interface? What about the following code? Int I =-42; unsigned w = I; cout Let's take a look at the

Go Language Learning Note 10: StructureThe structure syntax of the go language is similar to the C language. The concept of structs is similar to the class in high-level language java.Definition of structural bodyThe struct has two keyword type and struct, and a struct name is sandwiched between the two. All the member variables are written in curly braces, and the types of these variables are specified. Us

two people have the same birthday? (ignoring the fact that leap years, that is, 365 days a year)The probability of calculating certain things can often be converted to calculate their relative faces first. In this example, we can calculate the probability that everyone's birthdays are different, that is: 365/365 * 364/365 * 363/365 * ... * (365-49)/365, so that at least two people birthday the same probability is the value of this. public static double caculateprobability (int n) {

reference. Virtual references do not have too much impact on the object itselfThe object does not even feel the existence of a virtual reference. If an object has only one virtual reference, it is roughly the same as a non-referenced effect. Virtual PrimerThe virtual reference cannot be used alone, and the virtual reference must be combined with the reference queue (Referencequeue) in order to be used primarily to track the state of the object being garbage collectedUse.The reference object is
