Factorial , Armstrong numbers : Logic building (4)

Program to find the Factorial of a number

      int inputNum;

      int i;

      int factorial = 1;

      int value;

      printf("Please Enter Number less than or equal to 10:: ");

      scanf("%d",&inputNum);

     

      if(inputNum <= 10)

      {

      for(i =inputNum; i >= 1 ; i--)

      {

            value = i * factorial;

            printf("\n%d * %d = %d\n" , i,factorial,value);

            factorial = value;

      }

      printf("\nFactorial of %d is %d", inputNum,factorial );

      }

      else

      {

            printf("Please enter number less than or equal to 10");

      }

Program to print out all Armstrong numbers between given numbers

      int inputNum;

      int i;

      int armstrongNum ;

      int j;

      int digit;

      printf("Please Enter Number max limit");

      scanf("%d",&inputNum);

     

      for(i =1; i<= inputNum ; i++)

      {

            armstrongNum = 0;

            j = i;

            while( j > 0)

            {

                  digit = j%10;

                  armstrongNum += digit*digit*digit;

                   j = j/10;

            }

            if(armstrongNum == i)

            {

                  printf("%d\n", armstrongNum);

            }

      }
