  criteria:
  
  You can not use % operator

  Re: 1. Write a Simple C-program to print if a given number is even or odd
  
  #include
  void check(int n);
  void main()
  {
  int n;
  printf("\n Enter the number \n");
  scanf("%d",&n);
  check(n);
  }
  void check(int n)
  {
  int temp=n;
  for(int i=0;i {
  n=n-2;
  }
  if(n==0)
  printf("%d is even",temp);
  else
  printf("%d is odd",temp);
  }
  
  is this correct

  Bravo Harish..................... Great work!

  Here is the Second Question: Write a Simple C program that Scan an even number
  
  Criteria:
  
  Once user gives an input, the scanning part must check if the number is even or not and should keep prompting the user for a valid even number input. if user fails to input correct number in 5 attempts, program should terminate.

  Great Going Harish. Now try this with a do-while loop
  
  Do while is the best technique for validating. Just try out. That is the most efficient method. I know you will do this.

  Re: Great Going Harish. Now try this with a do-while loop
  
  #include
  #include
  void check(int n);
  void main()
  {
  int n,i=1;
  do
  {
  printf("\n Enter a valid even number number \n");
  scanf("%d",&n);
  i++;
  if(n%2!=0)
  continue;
  else
  {
  printf("%d is even\n",n);
  break;
  }
  }while(i<=5);
  exit(0);
  }
  
  ok did intrepret your question properly?
  
  and as i know for and do while execute same no. times here.can i know y is do while efficient?

  Ali....that was what exactly i was looking for and that is exactly how it must be done.

  Ok The Next One: 3. A Simple Program to Find the Factorial of a Number
  
  But the Criteria is You can not use any sort of Loops: while,for, do while. And Recursion is also not permitted.

  My code for Odd-Even numbers.
  

  #include
  //simplycoder
  
  using namespace std;
  int main(int argc,char**argv)
  
  {
      int num;
      scanf("%d",&num);
      num&1?printf("ODD\n"):printf("EVEN\n");
  system("PAUSE");
  return 0;
  }

  @simplycoder, This is what I was Expecting. Professionally Done and you are "My Programmer of The day" . Real cool.

  Nothing much to think of rather than Gamma-Functions and so on.
  I coded many series,out of which this series gave me the best and most accurate solution out of all.
  This approximation is called as Nemes approximation.
  

  #include
  #include
  //simplycoder
  
  using namespace std;
  int main(int argc,char**argv)
  
  {
      int x;
      scanf("%d",&x);
    
            int z=x+1;
  
     double pi=3.1415926535897932;
     double e=2.71828182845904523;
   
     double term1=sqrt(2.0*pi/z);
     double term2=1.0/e;
     double term3=(12*z-1/(10*z));
     double term4=z+1.0/term3;
     term4=term4*term2;
     term4=pow(term4,z);
     term4=round(term4*term1);
      cout<<"n "<

  Again Spot On. But I would Prefer Some more approaches. Lemme know how many of Engineers here can Think Out of the Box!

  My code for Odd-Even numbers.
  

  
      num&1?printf("ODD\n"):printf("EVEN\n");
  
  }

  @simply coder please explain how this woks...
• 

  simplycoder

  Its binary maths.
  Refer to my previous tutorial which involves bit-operators for more explanation.
  In short,all odd numbers have their last bit set to be 1 and all even number have last bit set to 0.
  So the above code works,
  condition?cout<<...:cout<<..
  is similar to if-else.

  Next Assignment: 3) Find the Factorial of 65 in turbo C
  
  This is simplest isn't it? Find the factorial of 65 in Turbo C. If you are using boroland C++ or .Net, find the factorial of 1024 😀

  Next Assignment: Declare an Array in Turbo C which can store 100x100 double values. Store and retrieve the values. As Simple as that. 😀
• 

  simplycoder

  I would not want to spoil this for other members but here is the slightest hint.This is not to be considered as normal and easy problem for findinf factorial, largest data-type is not sufficient to fit in all the numbers.
  Hint: use arrays.

  Array size is too large !!! 😐 dont know what to do .... let others try.. 😒
