I/O problem

[Zhao Le]

For each line of input produce one line of output containing a floating point number with ten digits after the decimal point.

such as this kind of problem how should I use the I/O fuction?

In C I can use the printf("%.10f",...);

but I cannot find any function in C++.

I have tried cout.precision(10);

but this not mean that.

Hope anyone can help.

Try something like

Code: Select all

cout.setf(ios::fixed);
cout.setf(ios::showpoint);
cout.precision(10); 

Zero will be printed as 0.0000000000. Is this what you want?
