In C language:

Implement function char *delete_comments(char *input) that removes C comments from program stored at input. input variable points to dynamically allocated memory (malloc, realloc, free). The function returns pointer to the polished program. You may allocate a new memory block for the output, or modify the content directly in the input buffer.

Youll need to process two types of comments:

• Traditional block comments delimited by /* and */. These comments may span multiple lines. You should remove only characters starting from /* and ending to */ and for example leave any following newlines untouched.

• Line comments starting with // until the newline character. In this case, newline character must also be removed.

The function calling delete_comments only handles return pointer from delete_ comments. It does not allocate memory for any pointers. One way to implement delete_comments function is to allocate memory for destination string. However, if new memory is allocated then the original memory in input must be released after use.
