Information: If you need to know the entire system information can also be obtained from the/proc/stat, including CPU usage, disk space, memory swap, interrupt and so on.? CPU information: Use the/proc/cpuinfo file to obtain the current accurate information of the CPU.Load information: The/proc/loadavg file contains system payload information.? System memory Information: The/proc/meminfo file contains details about the system memory, which shows the amount of physical memory, the number of free
. such as (int *) malloc (the number of sizeof (int) * elements);Code:voidM_alloc () {//dynamically request 20 bytes of memory space, the first address of the memory space is placed in P int*p = (int*) malloc (5*sizeof(int)); //determine if the assignment was successful if(p!=NULL) {memset (void*) P,0,sizeof(p)); for(intI=0; i5; i++) {printf ("%d\t", *p++); } printf ("\ n"); //if it succeeds, the data can be stored.*p =1; * (p+1) =Ten; * (p+2)
the difference between = = and the Equals method and the application of Integer and string
= = compares the address memory addresses of two objects, while equals compares the values of two objects.For example, the Equals comparison method of string, first call = = to determine whether the same, and then determine whether the object value is the same char array. integer and int = = Operations
the integer and int = = are judged primarily by the address. Example below
int i = m;
Integer i1 = m;

Today, I downloaded an Excel2003 document. I am very interested in some functions, but I am depressed that the document is encrypted and all functions are set to read-only attributes! Click "undo worksheet" in the Excel menu, prompting you to enter the password! In the past, I searched for a VBA macro Cracking Method on the Internet, and it was a success! There are really many cool people! I have to admire it. Let's talk about this method below.

Main function: Operation primary arithmetic, can choose subtraction and mixed operation.Design idea: First of all, think about the range of arithmetic, consider the arithmetic ability of elementary school students, then classify operation method, divide into subtraction mixed operation,Then you can choose whether to continue to do or quit the program, you can summarize the correct or wrong number of questions, convenient calculation and wrong number of problems.Source:/*Primary Arithmetic*/#incl
How to unblock Excel worksheet password protectionExcel pops up "The cell or chart you are trying to change is protected and is therefore read-only." To modify a protected cell or chart, first use the Unprotect Sheet command (in the Change group on the Review tab) to unprotect. You may be prompted to enter a password.What should be done to solve this problem? After research, two ways to solve the Excel worksheet protection code are found.One, VBA macro code crack method:First step: Open the file

Ugly number IIWrite a program to find the n -th ugly number.Ugly numbers is positive numbers whose prime factors only include 2, 3, 5 . For example, is the sequence of the first 1, 2, 3, 4, 5, 6, 8, 9, 10, 12 10 ugly numbers.Note that's 1 typically treated as an ugly number.The time complexity will be high if the number is not ugly by the judge. Here can be used to determine how many primes in K this problem solution, a little flexible.The first 1 is ugly number, and the following is the minimum
When writing a program in C ++, you often need to call other functions in a function. In this case, you will consider using a function pointer. A function can call other functions. In a well-designed program, each function has a specific purpose, the use of common function pointers.
First, let's look at the following example:
# IncludeString>
# IncludeVector>
# IncludeIostream>
Using namespace std;
Bool IsRed (string color ){
Return (Color= "Red ");
}

Bind is a set of templates for function bindings. When you bind a function, you can specify some or all of the parameters, you can specify no parameters, and you can adjust the order of each parameter. For unspecified parameters, you can use the placeholder _1, _2, and _3 to represent them. 1 represents the 1th parameter of the bound function, _2 represents the 2nd parameter of the bound function, and so on.Bind can be bound to normal functions, function objects, member functions of a class,
