program for sum of factorail....
a0/n!+a1x/(n-1)!+a2x^2/(n-2)!....a^nx^n?
a0/n!+a1x/(n-1)!+a2x^2/(n-2)!....a^nx^n?

Use a for loop, for each loop iteration calculated the value of the current term and then add the result to a variable that was initialised before the loop started. At the end of the loop the variable will contain your result, assuming that the maths remained with-in the bounds of the platform. -
It might be a good idea to use a function that calculates the factorial of a given non-negative integer n (n!).Comment

Be careful, n doesn't have to be very large before n! is too large to fit in the standard C integral types.- 9! > minimum value of USHRT_MAX
- 9! > minimum value of UINT_MAX
- 13! > minimum value of ULONG_MAX
- 21! > minimum value of ULLONG_MAX
