Fibonacci series ( for loop )

     Fibonacci series ( for loop )     So here is the code given below how to use for loop  in C++.  So here we go to the code. Just don't copy the code just go for its explanation given below the code. It may guide/help your for your learning and remembrance of the code. Fibonacci series #include<iostream.h> #include<conio.h> void main(){ clrscr(); int prev = 0, curr = 1, next, num; cout<<"Enter the number of elements : "; cin>>num; cout<<prev<<" "<<curr<<" "; for( int i = 2; i < num; i++ ){ next = prev + curr; cout<<next<<" "; prev = curr; curr = next; } getch(); } Explanation  of Code The header tags. #include<iostream.h>  #include<conio.h>  Then the  main()  function is declared. void main() clrscr();  is a function use to clear the output console screen. int  is use to initialize variables  prev, curr, next & num .  int prev = 0,
