Question
Please code using C++ and only use the header <iostream>. Any use of additional headers will not be accepted. Thank you.

Transcribed Image Text:**Problem 15: points.cpp**
**Objective:**
Develop a program that performs the following tasks:
1. **Input:** Read 10 pairs of Cartesian coordinates from a file named "points.txt".
2. **Sorting Criteria:**
- Sort by increasing x-values.
- Sort by decreasing y-values.
- Sort by increasing distance from the origin (calculated using the formula √(x² + y²)).
3. **Implementation Requirements:**
- Utilize only one sorting routine to achieve all sorting tasks.
- Employ an enumerated data type to track the sorting field.
- Define the number of coordinate pairs (10) as a global constant.
This exercise is designed to enhance your ability to manipulate data structures, reinforce your understanding of sorting algorithms, and demonstrate the use of enumerated types in control flow.

Allow the user to specify the current year’s population, the number of years and the annual growth rate. Use a for loop to compute and display each year, starting with the current year and the corresponding population.the formula would be to ADD versus SUBTRACT as in:i. dblTotal = dblTotal + (dblTotal * desiredGrowthRate)ii. Sample list box output would be (don’t forget to clear)1. Year 0: - 10,0002. Year 1: - 10,500 (if the growth is 5%) etcarrow_forward

Remember to use the Auto Size and Border Styleproperties.The program should read the number of units sold and figure a base cost. Theunits cost $99 each. A discount should then be figured and subtracted from thebase cost.
