Specifically deleting already written texts has no way. But you can replace the content of what has already been written on the line where the cursor is.
The tag " t" returns the cursor at the beginning of the line, what is written will replace the previous text. However if the new text is smaller than the previous one the previous characters of the end will be kept.
Ex:
printf("Texto anterior");
printf("\rFrase");
/*
Saída
Frase anterior
*/
To return a character is used " b". Ex:
printf("Pedro foi morto");
printf("\b\b\b\b\b\b\b\b\b\b se suicidou");
/*
Saída
Pedro se suicidou
*/
There is no way to move the cursor back to top lines or change other lines, only the line where the cursor is.
