Write a program using a beginner C language which calculates the value of ? from the series ?=(4/1)-(4/3)+(4/5)-(4/7)+(4/9)-(4/11)+... Print a table that shows the value of ? approximated by one term of the infinite series, by two terms, by three terms and so on (until 20 terms). How many terms of this series do you have to use before you first get 3.14? 3.141? 3.1415? 3.14159?
