Increment  and Decrements

• Post Increment   like      a++
• Pre Increment     like      ++a             

a++;      <=>      a=a+1;

++a;       <=>      a=a+1;  

Logical operators

       &&           AND              if(cond1 && cond2){}

       ||            OR                 if(cond1 || cond2){}

        !              NOT               if(!(cond1 == cond2)){}

if (cond1)
    {
         statement1;
         statement2;
    }

else 
    {
        statement3; 
        statement4;
        statement5; 
    }

if-else

else- if

if (cond1)
    {
        statement1;
        statement2;
    }

else if(cond2)
    {
        statement3; 
        statement4;   
    }

else if(cond3)
    {
        statement5; 
        statement6;   
    }

else 
    {
        statement6; 
        statement7;   
    }

while loop

initialization;

while(condition)

{

     statement1;
     statement2;
     statement3;

     increment;
