Evaluating Functions

#include <bits/stdc++.h>
#include <boost/multiprecision/cpp_int.hpp>
using boost::multiprecision::cpp_int;
using namespace std;

int main() {
cpp_int x;
cin>>x;
cpp_int ans=(4xxx)+(5xx)-(6x)+14;
cout<<ans;
return 0;
}
The ide cannot understand the boost library, has it not been added to this ide???

@duttrohan0302
the ide is configured to use just specific header files so the cb ide is not configured to use the same
its mainly desgined for competitve programming, like this boost library is very oftenly used. so the code does not work on CB ide
