The C++ program reads employee data from an input file, calculates updated salaries after a pay increase, and writes the results to an output file. It opens input and output files, declares variables to store employee names, salaries, and pay increase percentages. It then reads and processes the data for three employees, calculating the new salary as the current salary increased by the pay increase percentage, and writes the results to the output file.

inFile.open("Ch3_Ex6Data.txt");
outFile.open("Ch3_Ex6Output.txt");
cout<<fixed<<showpoint<<setprecision(2);
//First Employee
inFile>>lastName>>firstName>>currentSalary>>payIncrease;
updatedSalary= currentSalary* (1+(payIncrease*0.01));
outFile<< firstName<< ""<< lastName<< ""<< updatedSalary<< endl;
