[ad_1] Your program return the factorial when m = 1. Take this example: (m=1, n=4) 4 != 1 -> so you call recursively prod(1, 3) 3 != 1 -> so you call recursively prod(1, 2) 2 != 1 -> so you call recursively prod(1, 1) 1 == 1 -> you return 1 to the last … Read more
[ad_1] If DeliveryGoal is a string, then just declare it as a string literal: “88%” If it is a double, then parse the double and add the symbol: string percent = (val * 100).ToString() + “%”; Alternatively, you can have the ToString method format the double for you: string percent = val.ToString(“P”); See the MSDN … Read more
