- B.
Hello Programmers
- C.
HelloProgrammers
- D.
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:

What is the output - #include int main() { cout << "\ajay"; return 0; }
- A.
\ajay
- B.
Ajay
- C.
Jay
- D.
\a jay
Correct Answer
C. JayExplanation
The code snippet is using the escape sequence "\a" which represents the alert or bell character. When this character is encountered, it produces an audible or visual alert. 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:

What is the output - #include int main() { cout << "RAM\rLAL"; return 0; }
- A.
LAL
- B.
RAM LAL
- C.
RAM\rLAL
- D.
RALAL
Correct Answer
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:

Surya\rDiv
Correct Answer
A. DivyaExplanation
The C++ code uses the escape sequence "\r" to move the cursor to the beginning of the line. When "Surya" is printed followed by "\r", it moves the cursor back to the beginning of the line. Then "Div" is printed, overwriting "Surya" with "Div". As a result, the final output is "Divya".Rate this question:
