C++ Control Statement(कण्ट्रोल स्टेटमेंट)

हेलो Students 
आज हम लोग कण्ट्रोल स्टेटमेंट के बारे में पढेंगे | ये कण्ट्रोल स्टेटमेंट हमारी प्रोग्रामिंग लैंग्वेज में बहुत usefull होता है ये स्टेटमेंट आपको बताते है की हम प्रोग्राम को कैसे बना सकते है | 
तो चलते है। ...... 

 C++ if-else
In C++ programming, if statement is used to test the condition. There are various types of if statements in C++.

  • if statement
  • if-else statement
  • nested if statement
  • if-else-if ladder

C++  if  Statement

The C++ if statement tests the condition. It is executed if condition is true.

if(Condition)
{

// Code to be executed

}



#include <iostream.h> //Input output Stream Header File


   int main ()

 {  

   int num = 10;  // num = variable, int= Data Type
  
            if (num % 2 == 0)  
  
            {    

                cout<<"It is even number";    

            }   

   return 0;  
}  

if num=10 and num is modulous 2 equal to Zero means मैंने २ से डिवाइड  पर Remainder is Zero So the number is Even Number .



C++ IF-else Statement


The C++ if-else statement also tests the condition. It executes if block if condition is true otherwise else block is executed.



if(condition)
{    
//code if condition is true    
}
Else
{    
//code if condition is false    
}    


C++ If-else Example


#include <iostream>  

int main () 
{  

   int num = 11;   

            if (num % 2 == 0)    
            {    
                cout<<"It is even number";    
            }   
            else  
            {    
                cout<<"It is odd number";    
            }  
   return 0;  
}  

C++ If-else Example: with input from user


#include <iostream.h>  

int main () 
{  
    int num;  

    cout<<"Enter a Number: ";  

    cin>>num;  

            if (num % 2 == 0)    
            {    
                cout<<"It is even number";    
            }   
            else  
            {    
                cout<<"It is odd number";    
            }  
   return 0;  
}  


Output:
Enter a number:11
It is odd number
Output:
Enter a number:12
It is even number

C++ IF-else-if ladder Statement


The C++ if-else-if ladder statement executes one condition from multiple statements.


if(condition1)
{    
//code to be executed if condition1 is true    
}else if(condition2)
{    
//code to be executed if condition2 is true    
}    
else if(condition3)
{    
//code to be executed if condition3 is true    
}    
...    
Else
{    
//code to be executed if all the conditions are false    
}

Memory Hierarchy

Memory Hierarchy A memory unit is an essential component in any digital computer since it is needed for storing programs and data. Typically, a memory unit can be classified into two categories: The memory unit that establishes direct communication with the CPU is called  Main Memory . The main memory is often referred to as RAM (Random Access Memory). The memory units that provide backup storage are called  Auxiliary Memory . For instance, magnetic disks and magnetic tapes are the most commonly used auxiliary memories. Apart from the basic classifications of a memory unit, the memory hierarchy consists all of the storage devices available in a computer system ranging from the slow but high-capacity auxiliary memory to relatively faster main memory. The following image illustrates the components in a typical memory hierarchy. Auxiliary Memory Auxiliary memory is known as the lowest-cost, highest-capacity and slowest-access storage in a computer system. Auxiliar
