Question

 What is the output of the following code:  #include <fstream> #include <iomanip> #include <string> using namespace std; int main() {  string name_str = "John Paul Jones";  double height = 175.21345;  double income = 1793.3421;  cout <<  "12345678901234567890123456789012345678901234567890 "      << fixed << showpoint << left << setfill('.')      << setw(30) << name_str      << setprecision(1) << setfill(' ') << setw(10) << height << '$'       << right << setprecision(2) << setw(8) << income << endl;   return 0; }

Explanation / Answer

12345678901234567890123456789012345678901234567890

John Paul Jones...............175.2 $ 1793.34

clearly,first line will be printed.

fixed:write floating-point values in fixed-point notation

showpoint:When the showpoint format flag is set, the decimal point is always written for floating point values inserted into the stream (even for those whose decimal part is zero).

left:the output is padded to the field width appending fill charecters at the end... 1

setfill(.):Sets . as the stream's fill charecters...... 2

setw :Sets the field width to be used on output operations..... 3

from 1 2 n 3...in 2nd line ,in first 30 charecters at first name_str will be printed n then (.) ,after that height will be printed...

then in next 10 charecter will be height with one digit after decimal n spaces as setprecision(1) .

nd next 8 char will be income with 2 digits after decimaland a $ sign in the begining

so clearly we can get the output.
