HeProgrammers
Correct Answer
D. HeProgrammersExplanation
The output of this code is "HeProgrammers". The "\b" escape sequence is a backspace character, which moves the cursor back one position. In this code, there are three backspace characters ("\b\b\b") immediately after the word "Hello". So when the code is executed, the cursor moves back three positions and overwrites the characters "llo" with "P", resulting in the output "HeProgrammers".Rate this question:

However, in this case, the output will not produce an audible or visual alert because it is being printed to the console. Therefore, the output will be "jay" printed on separate lines.Rate this question:

A. LALExplanation
The output of the given code will be "LAL". This is because the "\r" character is a carriage return character, which moves the cursor back to the beginning of the line. So when the code is executed, it first prints "RAM", then the carriage return moves the cursor back to the beginning of the line, and then "LAL" is printed, overwriting the "RA" from "RAM". Therefore, the final output is "LAL".Rate this question:
