Commonly used data input and output functionsThe following is just a personal study note, because I am also just contact, so there may be errors, if there are errors, please point out1. StatementsStatement: is to complete a certain operation task,

1 passing object names directlyWhen passing a function parameter with the object name, a new object is created when the function is called, and he is a copy of the formal parameter object.For example:#include using namespace Std;Class

First, the definition: 数组下标在2个以上时，改数组称为多维数组。 （所谓多维数组是多个一维数组的嵌套。）Two, three-dimensional array traversal:forint0 ; i forint0 ; j forint0 ; k Iii. access to multidimensional arrays1. Multidimensional array access elements: array name [subscript]

In the simplest one-dimensional array description:#include #include void main () {int arr[] = {1,3,5};//General array assignment int arr1[3];for (int i =0; i C + + (suspect 1) arrays and pointersC + + (suspect 2) const externc/C + + (suspect 3) c.

I. Declarationint *p ; // int * ）( p )Second, wild pointer--avoidance method1) The pointer variable must be initialized to NULL, because any pointer variable that was just created will not automatically become a null pointer, and its default

stringThe lookup function for the class:intFindCharCintpos =0)Const;//start looking for character C at the position of the current string from POSintFindConst Char*s,intpos =0)Const;//Find the position of the string s in the current string starting

This paper mainly discusses the difference between class and struct. Why is it a difference, not a common denominator? Because in the vast majority of cases, class and struct can actually be replaced by each other,So what is the difference, I summed

#region to remove duplicate data from a divisor group///////or to remove duplicate data from/// requires the addition of a heavy array // non-repeating array public static string[] Delrepeatdata ( String[] Array)

Recently in the C + +, and then read more about the object-oriented knowledge points, good memory is not as bad as the written, summed up the classification.In object-oriented, inheritance is a very important basic concept. When you derive a new

1. StaticStatic variables, which allocate memory in the static area, are not stored in the stack area.Static declarations and definitions are carried out at the same time.The static modified global variables are visible only in the compilation unit

Consideration of the efficiency of the programTemplate inlinevoid swap (t *a, T * b) { T tmp (*a); *a = *b; *b = tmp;}The above code actually makes three copies, which is obviously a waste of time if the size of the type is larger. The

Two ways of operator overloadingFor many operators, you can choose to use member functions or non-member functions to implement operator overloading. In general, a non-member function should be a friend function so that the private data of the class

Should first look at the C language refers to all the bit binary arithmetic bit calculation. Even if the input is a decimal number, the memory is stored in binary form. "=0. Function: The integer number a press bits to the left to move the M-bit,

Just is the problem that we encountered in the code, before superficial understanding, only with g++ compile without error, now to cross the platform to Windows under the problem.Full text reprinted from: http://user.qzone.qq.com/75172588/blog/124816

　　The serial port is the standard interface of the computer, and now the PC (personal computer) generally has at least two serial ports COM1 and COM2. Serial port is widely used in data communication, computer network and distributed industrial
