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:
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.
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.
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
std::this_thread::sleep_for(std::chrono::milliseconds(500));
}
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.
