write a C++ program to read the data from a file and put in a 2d array. This data contains the details of each sales person records. After the details are read and inserted, now calculate the grand total of each sales person and find out the sales person of the month.
Sure! I can help you with that. Here's the explanation of the steps involved in writing a C++ program to achieve the desired functionality:
1. First, you need to create a file that contains the salesperson data. Each line in the file should represent the details of a salesperson, with each detail separated by a delimiter (such as a comma or space).
2. In your C++ program, you should include the necessary header files for file handling and using arrays, such as `<iostream>`, `<fstream>`, and `<string>`.
3. Define a 2D array to store the salesperson data. The number of rows in the array should correspond to the number of salespersons, and the number of columns should represent the number of details for each salesperson.
4. Open the file in read mode using the `ifstream` object, and check if it opened successfully. If it fails to open, display an error message and exit the program.
5. Use a loop to read each line of the file using the `getline()` function until the end of the file. Inside the loop, split each line into individual details using the delimiter and store them in the corresponding elements of the 2D array.
6. After reading and storing the data, close the file using the `close()` function.
7. To calculate the grand total for each salesperson, iterate over each row of the 2D array and sum up the salesperson's details. Store the grand totals in a separate 1D array.
8. Determine the maximum grand total from the 1D array and keep track of the corresponding salesperson's index.
9. Finally, display the grand totals for each salesperson and announce the salesperson of the month using the obtained index.
Here's a skeleton code outlining the above steps:
```cpp
#include <iostream>
#include <fstream>
#include <string>
const int MAX_SALESPERSON = 10; // Maximum number of salespersons
const int NUM_DETAILS = 5; // Number of details for each salesperson
int main() {
std::string filename = "salesdata.txt"; // Replace with the actual file name
std::ifstream file(filename);
if (!file) {
std::cerr << "Error opening file: " << filename << std::endl;
return 1;
}
int sales[MAX_SALESPERSON][NUM_DETAILS] = {0}; // 2D array to store salesperson data
int grandTotal[MAX_SALESPERSON] = {0}; // Array to store grand totals
int salespersonOfMonth = 0; // Index of the salesperson with the highest total
// Step 5: Read and store the data
std::string line;
int salesperson = 0;
while (std::getline(file, line)) {
// Split the line into individual details and store them in the 2D array
// You can implement a separate function or use string manipulation functions to split the line
// Calculate the grand total for the current salesperson
// You can use a loop to sum up the details and store the total in the grandTotal array
// Check if the current salesperson's total is higher than the current highest total
// If so, update the salespersonOfMonth variable
// Increment the salesperson index
}
file.close();
// Step 9: Display the results
for (int i = 0; i < salesperson; i++) {
std::cout << "Salesperson " << i+1 << " grand total: " << grandTotal[i] << std::endl;
}
std::cout << "Salesperson of the Month: " << salespersonOfMonth + 1 << std::endl;
return 0;
}
```
