Explanation / Answer
PLEASE REFER BELOW CODE
#include<iostream>
#include<fstream>
#include<string>
#include <iomanip> // std::setprecision
using namespace std;
//creating structure for employee
typedef struct Employee
{
string last_name,first_name;
double cur_salary, per_pay;
}Employee;
int main()
{
//stream for output file
ofstream outfile;
//stream for input file
ifstream infile;
Employee E;
//opening input file
infile.open("Ch3_Ex6Data.txt");
//if file is absent
if(!infile)
{
cout<<"Error in opening file"<<endl;
return 0;
}
//creating output file
outfile.open("Ch3_Ex6Output.dat");
//if fail to create file
if(!outfile)
{
cout<<"Error in creating file"<<endl;
return 0;
}
//reading input file line by line
while(infile >> E.last_name >> E.first_name >> E.cur_salary >> E.per_pay)
{
//writing to output file
outfile<<E.first_name<<" "<<E.last_name<<" "<<fixed<<setprecision(2)<<(E.cur_salary + (E.per_pay * 0.01 * E.cur_salary))<<endl;
}
return 0;
}
//creating output file
outfile.open("Ch3_Ex6Output.dat");
//if fail to create file
if(!outfile)
{
cout<<"Error in creating file"<<endl;
return 0;
}
//reading input file line by line
while(infile >> E.last_name >> E.first_name >> E.cur_salary >> E.per_pay)
{
//writing to output file
outfile<<E.first_name<<" "<<E.last_name<<" "<<fixed<<setprecision(2)<<(E.cur_salary + (E.per_pay * 0.01 * E.cur_salary))<<endl;
}
return 0;
}
INPUT FILE IS Ch3_Ex6Data.txt
Miller Andrew 65789.87 5
Green Sheila 75892.56 6
Sethi Amit 74900.50 6.1
OUTPUT FILE IS Ch3_Ex6Output.dat.
Andrew Miller 69079.36
