Question

What are some potential risks associated with strcpy() function and how can they be mitigated in C

Answer 1

The primary risk with strcpy(): It does not perform bounds checking, which can lead to buffer overflows if the destination buffer isn't large enough to hold the source string. This can be mitigated by:

• Ensuring that the destination buffer is always large enough.

• Using safer alternative functions like strncpy, which allows for the maximum number of characters to be copied to be specified, reducing the risk of overflow.
