C or C++ : Unsafe function: gets

The gets function used is insecure because it can lead to a buffer overflow. This may lead to incorrect behavior or crash of the application.

The C library function char *gets(char *str) reads a line from stdin and stores it into the string pointed to by str. It stops when either the newline character is read or when the end-of-file is reached, whichever comes first. The function gets() is vulnerable to attacks such as buffer overflow and should not be used.
