SOURCE CODE:

#include <iostream>
#include <iomanip>

using namespace std;

int main()
{
float a=345.24681359;
std::cout << std::setprecision(3);
cout<<"Question e "<<std::scientific<<endl;
cout<<std::setfill('_')<<std::setw(10);
cout<<a;
cout<<endl;

std::cout << std::setprecision(4);
cout<<"Question f "<<std::defaultfloat<<endl;
cout<<a;
cout<<endl;
cout<<"Question g "<<std::defaultfloat<<endl;
cout<<a;
cout<<endl;
std::cout << std::setprecision(3);
cout<<"Question h "<<std::fixed<<endl;
cout<<"bb"<<a;
cout<<endl;
std::cout << std::setprecision(4);
cout<<"Question i "<<std::fixed<<endl;
cout<<std::setfill('*')<<std::setw(12);
cout<<a;
cout<<endl;
cout<<"Question j "<<std::hexfloat<<endl;
cout<<a;
cout<<endl;
return 0;
}
