using namespace std;

//Creating Employee Structure
struct Employee {
string firstname;
string lastname;
double currsal;
double increasePercent;
} emp;

int main() {

Employee emp[3];  
  
//defines an input stream for the data file  
ifstream dataIn;
  
//Defines an output stream for the data file
ofstream dataOut;
  
//Declaring variables
string lname,fname;
double csal,incPercent;
double updated_sal;
  
//Opening the input file
dataIn.open("D:\Ch3_Ex6Data.txt");
  
  
/* Getting the values from the input file and
* populate those values into Employee structure
*/
for(int i=0;i<3;i++)

   //Getting the values from the input txt file
   dataIn>>lname>>fname>>csal>>incPercent;
   emp[i].lastname=lname;
   emp[i].firstname=fname;
   emp[i].currsal=csal;
   emp[i].increasePercent=incPercent;
}
  
//Closing the intput file
dataIn.close();
  
//creating and Opening the output file
dataOut.open("D:\Ch3_Ex6Output.dat");
  
//Setting the precision
dataOut<<setprecision(2)<<fixed<<showpoint;

//Writing the data to the output file
for(int i=0;i<3;i++)
{
    updated_sal=emp[i].currsal+(emp[i].currsal*emp[i].increasePercent);
    //Writing the data to the output file
dataOut<<emp[i].firstname<<" "<<emp[i].lastname<<" "<<updated_sal<<endl;
}
  
//Closing the output file.
dataOut.close();
  
return 0;
}
