Choose the values after the following statement executes: b. ch = '2', x = 76. 5520 x 1850. setprecision (n) Sets the precision of floating -point numbers. It just gets stuck looping the first line from the input file over and over. View CODE_C++11Gaddis from CSCE 206 at Texas A&M University. My problem is that I need to display a special message that appears when the program hits the first 3.14 , and the first 3.141 .That special message should include in which iteration of the loop did the the number become 3.14 and 3.141 . #include <iomanip>. internal left right. Has no effect on input. ios_base& showpoint (ios_base& str) Parameters: This method accepts str as a parameter which is the stream for which the format flag is affected.
