Salary Program in C++ – 2nd C++ Practice Assignment

In this C++ Practice Assignment, the task is to write a salary program in c++. Then it will generate the salary of an employee as per the sales made by the employee. The requirements for generating sales are:

• Week 1 – User inputs the totals sales for week 1
• Week 2 – Call a function to generate a random number between 1000-5000
• Week 3 – User again manually inputs the total sales for week 3
• Week 4 – Generate a random number between 1000-5000 to get the total sales for week 4

After the generation of sale numbers for weeks 1 to 4, the total sales are then calculated. It then generates the total salary. The salary program in c++ then displays a pay slip showing the week number, weekly sales, weekly salary, which are formatted in columns, and the total salary for the month.
