Write a C++ program using a while loon for Programming Exercise 5.27 on p. 198 with the following change: Instead of displaying n for values of i shown, use a while loop to continue adding terms until it is accurate to 6 digits after the decimal point. pi = 4(1 - 1/3 + 1/5 - 1/7 + 1/9 - 1/11 +..)Display the following and turn in printouts of the program and the results. The number of terms needed to find n The value of it using acos(-1) using 10 digits alter the decimal point. The value of pi/2 found with the series using 10 digits alter the decimal point (the first 6 digits after the decimal point should match the value above)
