Answer :
Here's a C++ program that reads job titles and salary ranges from a text file, performs the required calculations and sorting, and provides the option to display the results on the console or write them to an output file:
cpp
Copy code
#include <iostream>
#include
#include
#include
const int MAX_JOBS = 20;
// Structure to hold job details
struct Job {
std::string title;
double lowSalary;
double highSalary;
double avgSalary;
};
void readJobsFromFile(Job jobs[], int& numJobs) {
std::ifstream inputFile("jobdata.txt");
if (!inputFile) {
std::cerr << "Error opening file." << std::endl;
exit(1);
}
std::string line;
int count = 0;
while (getline(inputFile, line)) {
jobs[count].title = line;
getline(inputFile, line);
jobs[count].lowSalary = std::stod(line.substr(0, line.find('-')));
jobs[count].highSalary = std::stod(line.substr(line.find('-') + 1));
jobs[count].avgSalary = (jobs[count].lowSalary + jobs[count].highSalary) / 2.0;
count++;
if (count == MAX_JOBS)
break;
}
numJobs = count;
inputFile.close();
}
void calculateAverageSalaries(const Job jobs[], const int numJobs, double avgSalaries[]) {
for (int i = 0; i < numJobs; i++) {
avgSalaries[i] = jobs[i].avgSalary;
}
}
void displayAverageSalaries(const Job jobs[], const double avgSalaries[], const int numJobs) {
std::cout << "Average Salaries:\n";
for (int i = 0; i < numJobs; i++) {
std::cout << jobs[i].title << ": " << avgSalaries[i] << std::endl;
}

}

std::string lowestTitle = jobs[0].title;

std::cout << jobs[i].title << " (" << jobs[i].lowSalary << " - " << jobs[i].highSalary << ")\n";
}
std::cout << std::endl;
}
void writeResultsToFile(const Job jobs[], const double avgSalaries[], const int numJobs) {
std::ofstream outputFile("job-stat.txt");
if (!outputFile) {
std::cerr << "Error creating output file." << std::endl;
exit(1);
}
outputFile << "Average Salaries:\n";
for (int i = 0; i < numJobs; i++) {

double lowest = avgSalaries[0];
