How to use setprecision in C

0 votes

I'm new to C++ and all I want to do is print my point number up to two digits. 

For example, if the number is 3.444, the output should be 3.44, and if the number is 99999.4234, the output should be 99999.42. 

How am I going to do that? 

The value changes over time. 

This is my code.

#include <iomanip.h>
#include <iomanip>
int main()
{
    double num1 = 3.12345678;
    cout << fixed << showpoint;
    cout << setprecision(2);
    cout << num1 << endl;
}

but its giving me an error, undefined fixed symbol.

What is the best way to use a HashMap in C++?

The ordered and unordered map containers (std::map and std::unordered map) are included in the standard library.  The items in an ordered map are sorted by key, and insert and access are in O (log n).  For ordered maps, the standard library often use red black trees.  However, this is only an implementation detail.  Insert and access are in O in an unordered map (1).  It is simply another term for a hashtable. An illustration using (ordered) std::map: #include <map> #include <iostream> #include <cassert> int main(int argc, char ...READ MORE
