No, incrementing a void pointer is not allowed.
Void pointers do not have a data type, so incrementing them is not possible.
Attempting to increment a void pointer will result in a compilation error.
To increment a pointer, it must be of a specific data type.

Interview Preparation Tips
Experience: I had a resume as per the standards laid down by our placement cell. The company did not look at the resume I had with me and it was just a formality.
Round: Test
Experience: The written test had questions on C programming. The topics from C were basically related to pointers, operators and functions. The paper also had questions from Digital Electronics. These were mostly from chips and registers. There was another section for Aptitude also in the test. There were questions from simple electronics as well but I had no idea about them. The duration of the test was around 1 hour.
Tips: For Written test i would recommend ‘C by Yashwant Kanetkar’ and the book by Salle Mahanand for Digital Electronics.
Round: Technical Interview
Experience: The first interview was a technical interview. The whole interview revolved around the concept of Bit wise operator which is a concept in C. They also asked me questions on Digital electronics which were mainly based on the layout of NAND, AND, OR Gates. They were not sure about my proficiency in C so they also asked me to code some simple problems in C. The technical interview lasted pretty long.
Round: HR Interview
Experience: The second round was an HR Interview. It was simply a formality for those who had performed well in the technical interview. They asked me general questions about the talk they had given as well as they enquired about me and my family background.
Tips: The company looks for people who are proficient in C. So, in depth knowledge of the language is needed before the interview.
