Design a program that reads a file called sales.txt containing the following data: Jane, 215.5,445.5,910.0 John, 825.0,250.5,675.0 Bill,0.0,999.15 Each line has a employee's name and their weekly sales totals all separated by commas. Some employees have taken vacation some weeks so no numbers are captured for those weeks. Create a function that takes a list of floats and returns the average value for those numbers. After reading the information from the file, use a for loop to calculate the sales average using your new average function for each employee and display the following output to the screen. Jane, average sales: 523.67 John, average sales: 583.50 Bill, average sales: 499.56

Files Class Activity Write a program to write your first name (hard coded) to the screen and possibly to a file whose name is passed into the program from the command line. It can be written in upper or lower case or mixed case as the default. Usage: writer [-f filename] If the -f option is included with a filename, then create a file with that name or overwrite a previously existing file and write your name in on the first line. If the -f option is not included, then only write your name to the screen followed by a newline. Use a copy of the original getopt to parse the command line. Be sure to test whether a file open succeeds or not and close any file you open when done.
// Flowers.cpp - This program reads names of flowers and whether they are grown in shade or sun from an input // file and prints the information to the user's screen. // Input: flowers.dat. // Output: Names of flowers and the words sun or shade. #include <fstream> #include <iostream> #include <string> using namespace std; int main() { // Declare variables here // Open input file // Write while loop that reads records from file. fin >> flowerName; // Print flower name using the following format //cout << var << " grows in the " << var2 << endl; fin.close(); return 0; } // End of main function
