How to write to same line using C/C++

[Neo]

This is an answer to AU of DigitalSriLanka Facebook group.

1. First method using \r (carriage return)
This will return to beginning of line and draw the same thing over and over

Code: Select all

	int i;

	for (i = 0; i < 1000; i++){
		//printf("%d[2K", i);
		printf("\rThis is printed on the same line %d", i);
		Sleep(1000);
	}

2. Second method using \b (delete one character or backspace)
Notice that I'm writing 4 characters, so I know I have to delete exactly 4 bytes to delete to redraw only the number.

Code: Select all

	int i;

	printf("\rThis is printed on the same line %4d", 0);
	for (i = 0; i < 1000; i++){
		//printf("%d[2K", i);
		printf("\b\b\b\b%4d", i);
		Sleep(1000);
	}

First method is generally preferred. However you can select between them as appropriate.

You can try this too.
Printf("%d[2K",27); // delete entire line
printf("\r%d",I); // move cursor to start of line
