INTERVIEW QUESTIONS C STRINGS IN C DETAILS

Question: Tell me the difference between strdup and strcpy?

Answer: strcpy will not allocate the memory for the copy for you, which means you have to give it not only the pointer to the string to copy, but also a pointer to the place to copy it to, which you have set up yourself. strdup will grab itself a place to copy the string to, which you will have to free up later when you don't need the copy anymore.
