What are the differences between strdup and strcpy functions used in C?

In: C Programming [Edit categories]

Answer:

Answer

strcpy - copy a string to a location YOU created (you create the location, make sure that the source string will have enough room there and afterwards use strcpy to copy)

strdup - copy a string to a location that will be created by the function. The function will allocate space, make sure that your string will fit there and copy the string. Will return a pointer to the created area.
