點樣可以??: formula:{ 圓周率(3.14) = 4- (4/3) (4/5) - (4/7) (4/9) - (4/11) ... } Print a table that shows the value of 圓周率 approximated by 1 term of this series, by two terms, by three terms, etc. How mcuh if this terms of the series do you have to use before you first get 3.14? 拜託曬各位大大..... 另外追加: Write a programme to print out hollow square ...(input must within 2-20) requset user to input a non-negative integer to show different square~ for example: input = 5 : ***** * * * * * * ***** input = 6 : ****** * * * * * * * * ****** besides use switch case to show 2-20 既 square.........
