how to refresh multiple command lines in C++ stream

Refreshing Multiple Command Lines in C++ Stream

To refresh multiple command lines in C++ stream, you can follow these steps:

  1. Use Escape Sequences: Use the escape sequence "\033[A" to move the cursor one line upwards within the terminal. You can use this to overwrite the previous line in the terminal.

  2. Use std::cout and std::flush: Utilize the std::cout object to output the new content, followed by std::flush to ensure that the content is immediately flushed to the terminal.

  3. Repeat for Each Line: Repeat the above steps for each line that you want to refresh in the command line interface.

Here's an example of how you can achieve this:

#include <iostream>
#include <chrono>
#include <thread>

int main() {
    for (int i = 0; i < 10; ++i) {
        // Move the cursor one line upwards
        std::cout << "\033[A";

        // Output the new content and flush it
        std::cout << "Updated content for line " << i << std::flush;

        // Wait for a short duration before refreshing the next line

    return 0;

In this example, the program iterates over 10 lines, refreshing each line in the terminal by moving the cursor up one line and outputting the updated content. Additionally, a short delay is added between each refresh using std::this_thread::sleep_for.
