c++ progress bar

To create a progress bar in C++, you can follow these steps:

1. Include the necessary header files: You will need to include the <iostream> and <windows.h> header files. The <iostream> file is required for input/output operations, and the <windows.h> file is needed to access the Windows API functions.

2. Define the function to update the progress bar: Create a function, let's call it updateProgressBar(), that takes in two parameters: the current progress value and the total progress value. This function will update the progress bar accordingly.

3. Calculate the progress percentage: Inside the updateProgressBar() function, calculate the progress percentage by dividing the current progress value by the total progress value and multiplying it by 100.

4. Set the console cursor position: Use the SetConsoleCursorPosition() function from the Windows API to set the console cursor position to a specific location. This will allow you to overwrite the existing progress bar with the updated one.

5. Print the progress bar: Create a loop that iterates from 0 to the progress percentage. Inside the loop, print a "#" character to represent the progress. You can also print a "-" character for the remaining space.

6. Display the progress percentage: After the loop, use the std::cout statement to display the progress percentage.

7. Call the updateProgressBar() function: In your main program, call the updateProgressBar() function whenever you want to update the progress bar. Pass in the current progress value and the total progress value as arguments.

That's it! By following these steps, you should be able to create a progress bar in C++. Remember to include the necessary error handling and additional functionality as per your requirements.
