C PROGRAM FOR NUMBER VALIDITY FOR DIFFERENT CONDITIONS

This program checks the validity of two numbers.a valid input would satisfy following conditions:
a)inputs should be integers
b)each no. is between 1 and 100
c)two no.s are not divisible to each other
d)difference of two is not less than 1
e)sum of these should not exceed 100

      its value will increase by 1.if its value becomes 5 at the end then all the conditions are satisfying otherwise not*/

/*this procedure will calculate that the number is an integer or not.Any integer devided by 2 will always give remainder 0,1 or -1.(no1-2*x) in this formula x is not a floating point no. so it will neglect no.s after decimal.in this way remainder will always be 0,1 or -1 if no1 is an integer*/
