i was hoping you could first run my program and have a look. It is extremely basic. i didnt know how to output the commission values in from case 3 (line 87 to 91) and output them in case 4, and i was hoping you could help me with any suggestions
Thanks
Code:#include <iostream> //the usual headers are used including string #include <string> #include <conio.h> void WeeklySales(); //these are functions i created main() { int number; // declare variables char answer; double sales, sales_amount, quantity, total_sales, vat, commission; sales = (sales_amount * quantity); //initialise variables total_sales = (sales + vat); do { //start of a do-while loop //output displays the menu cout << "\n\n******Sales System******"; cout << ("\n\n"); cout << "1. Display Company Logo.\n"; endl; cout << "2. Input/Validate weekly sales data.\n";endl; cout << "3. Calculate weekly sales.\n";endl; cout << "4. Display reciept.\n";endl; cout << "5. SHUT DOWN & LOG OFF.\n";endl; cout << "\nEnter a number...\n";endl; //prompts the user cin >> number; //input cout << ("\n\n"); switch (number) //<--the expression is a variable (number) & controls //the switch the value of (number) is tested against a list of //constants.
