my problem ∏n=0 ^∞ x\ (n!) ^2 but my code did't work just say error: 'n' undefined near line 5 column 10 error: called from

x= (input("1.tam sayi: "));

n= (input("2.tam sayi: "));

function[S]=yanit6(x,n)

c=0;

for i =0:n

c= c+ (x\(factorial(n)^2))

end

end

you are not calling the function in what you post.

Your function is calculating a sum not a product.
