You can use std::setprecision() to control the number of decimal places:

Answer 2

You can use the built-in function setprecision
ex: float pi = 3.141590
cout << fixed << setprecision(2) << pi;

setprecision() when used with fixed provides you with precision to float values to the decimal number mentioned.
