Binary search algorithm=half-interval search

Binary search compares the target value to the middle element of the array; if they are unequal, the half in which the target cannot lie is eliminated and the search continues on the remaining half until it is successful. If the search ends with the remaining half being empty, the target is not in the array

Hash table


In computing, a hash table (hash map) is a data structure which implements an associative array abstract data type, a structure that can map keys to values.

// These are all assignments, not initializations
ماهو الفرق بين assignments و initializations

 class Something
{
private:
    int m_value1;
    double m_value2;
    char m_value3;
 
public:
    Something()
    {
        // These are all assignments, not initializations
        m_value1 = 1;
        m_value2 = 2.2;
        m_value3 = 'c';
    }
};

dynamic_cast

Dynamic typecasting is performed using dynamic_cast operator that can be applied only to pointers to classes. Type validation is performed at runtime. This means that the compiler does not check the data type applied for typecasting when dynamic_cast operator is used. If a pointer is converted to a data type which is not the actual type of an object, the result is NULL.

 dynamic_cast <type-id> ( expression ) 
  

The type-id parameter in angle brackets should point to a previously defined class type. Unlike C++, expression operand type can be of any value except for void.

 class CBar { }; 
class CFoo : public CBar { }; 
  
void OnStart() 
  { 
   CBar bar;     
//--- dynamic casting of *bar pointer type to *foo pointer is allowed 
   CFoo *foo = dynamic_cast<CFoo *>(&bar); // no critical error    
   Print(foo);                             // foo=NULL       
//--- an attempt to explicitly cast a Bar type object reference to a Foo type object is forbidden 
   foo=(CFoo *)&bar;                       // critical runtime error 
   Print(foo);                             // this string is not executed 
  }

الكود اسفل لو تشددنا

    for( uchar i=0;i<=27;i++) 
  

افضل من هذا الكود

    for( int i=0;i<=27;i++)

ما الفرق

 void OnStart() 
{ 
   for(int i=1;i<=5;i++) 
   { 
      static int count=1; 
      Print(i,"   ----A---- ",count); 
      count++; 
   } 
} 
  

or

 void OnStart() 
{ 
   for(int i=1;i<=5;i++) 
   { 
      int count=1; 
      Print(i,"   ----A---- ",count); 
      count++; 
   } 
}
