The C function strncpy is a safer version of strcpy with the following interface definition: char *strncpy(char *dest, const char *src, size_t n); where n specifies that at most n bytes of src are copied into the dest buffer. If the length of src is less than n, strncpy writes additional null bytes to dest to ensure that a total of n bytes are written. (a) (2pt) Why is strcpy unsafe? (b) (6pt) Give a concise implementation of strncpy according to the given descrip- tion of its functionality (note that this question is a "written component" in the sense that you need to embed your code within your submitted PDF file). C implementation is preferred. (c) (4pt) What problem of strcpy is solved by strncpy? (d) (4pt) Can strncpy still lead to buffer overflow? Explain your answer.
