Question

Simple C++: Getting an input file and doing calculations.

A company keeps the record of its employees in a text file. The text file is in the following format FirstName LastName ID Salary Write a program to read the text file and calculate the maximum salary. You then need to display the maximum salary and the FirstName, the LastName and the ID of the corresponding employee earning that maximum salary. You are permitted to use String data-type to handle the FirstName and the LastName. You DO NOT NEED to use arrays to solve this problem

Input file to be read from should be named "1030Prob1.dat" it will contain the following::

John Harris 11374 50000.00
Lisa Smith 11985 75000.00
Adam Johnson 12585 68500.00
Sheila Smith 11654 150000.00
Tristen Major 11274 75800.00
Yannic Lennart 15687 58000.00
Lorena Emil 17414 43000.00
Tereza Santeri 12597 48000.00

Answer 1

#include <iostream>
#include<fstream>
using namespace std;

int main()
{
ifstream inputFile;
inputFile.open("1030Prob1.dat");
char s[100];
int max = 0;
int count = 0;
string firstName, tempFirstName, lastName, tempLatName;
int id, tempId;
if (inputFile.is_open()) {
while (!inputFile.eof()) {

count++;
inputFile >> s;
if(count % 4 == 1){
tempFirstName = s;
}
else if(count % 4 == 2){
tempLatName = s;
}
else if(count % 4 == 3){
tempId = atoi(s);
}
else if(count % 4 == 0){
double salary = atoi(s);
if(max < salary){
max = salary;
lastName = firstName = tempFirstName;
tempLatName;
id = tempId;
}
}

}
}
cout<<"Maximum Salary: "<<max<<endl;
cout<<"First Name: "<<firstName<<" Last Name: "<<lastName<<" ID: "<<id<<endl;
inputFile.close();
return 0;

}

Output:

sh-4.3$ g++ -std-c++11-o main *.cpp sh-4.3$ main Maximum Salary: 150000 First Name: Sheila Last Name: Sheila ID: 11654
