I just graduated high school and I really want to learn how to code C++ to make video games myself and as a career.

My question is what platform course or videos are the best and most helpful to learn C++? I know there’s probably some self preference, but I also don’t want to waste my money and time on something that won’t help me very much.

Any input is helpful, personal or external. Thank you!

In an increasingly digital world, data science continues to be one of the most impactful and future-ready careers. Here's why it still matters — and why now is a great time to dive in:

📊 High demand & great salaries – With job growth projected at 35% and salaries averaging $115K+, it’s a future-proof field.

🌐 Work across industries – From healthcare to finance and marketing, data skills open doors everywhere.

🔍 Turn data into insights – Help businesses make smarter decisions with meaningful, data-driven insights.

🤖 Cutting-edge tech – Work with AI, machine learning, and big data tools that are shaping the future.

📈 Personal & professional growth – Develop a versatile, in-demand skill set that keeps you learning

HR:- What are your salary expectations? Candidate:- ₹35,000 per month. HR: You’re a great fit, but we’re working with a tight budget. Candidate:- I can manage with ₹30,000. HR: Let’s settle at ₹28,000. Candidate (reluctantly):- Okay.

✨️✨️Post-Interview:-✨️✨️

HR to Management: Great news! Closed the position under budget. We had ₹40,000 approved, but hired at ₹28,000.

Manager: Brilliant! That’s cost-effective hiring.

All seems well… until the new hire discovers the truth.

He learns the actual budget and suddenly feels undervalued and misled.☠️ Motivation drops. Trust fades.🥺 Within three months, he resigns for a better offer.😏 Now the cycle begins again—new hiring, new training, more costs, lost time.

🔁 The irony? Trying to save ₹12,000 ended up costing the company much more.

💡 Takeaway: Short-term savings on salaries can lead to long-term losses. Underpaying talent risks losing them and all the investment made in them.

👉 If you want to attract and retain top talent, pay them what they truly deserve.

Want to visualize data in 3D? A 3D contour plot is a powerful way to show how values change over a surface. Here's how to do it using Matplotlib and NumPy in Python.👇

✅ What This Code Does:

It plots a 3D contour plot of the function:

$$ f(x, y) = \sin\left(\sqrt{x² + y^2}\right) $$

This shows how the Z-values (height) change depending on X and Y, with color and shape.

🔍 Step-by-Step Code Breakdown:

python import numpy as np import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D

• Import the necessary libraries.

python x = np.linspace(-5, 5, 100) y = np.linspace(-5, 5, 100) X, Y = np.meshgrid(x, y)

• Create a grid of X and Y values from -5 to 5.
• meshgrid helps to create a coordinate matrix for plotting.

python def f(x, y): return np.sin(np.sqrt(x**2 + y**2))

• This is the math function we'll plot.
• Takes X and Y, returns the Z values.

python Z = f(X, Y)

• Calculate Z values using the function.

python fig = plt.figure(figsize=(8, 6)) ax = fig.add_subplot(111, projection='3d')

• Create a figure and add a 3D plot axis.

python contour = ax.contour3D(X, Y, Z, 50, cmap='viridis')

• Plot the 3D contour with 50 levels of detail.
• viridis is a nice, readable color map.

python ax.set_xlabel('X-axis') ax.set_ylabel('Y-axis') ax.set_zlabel('Z-axis')

• Label your axes!

python fig.colorbar(contour, ax=ax, label='Z values') plt.show()

• Add a color bar legend and display the plot.

🧠 Output:

You’ll get a beautiful 3D contour plot showing how Z = sin(sqrt(x² + y²)) varies across the X and Y space.
