C code implementation for generating random passwords

Problem description

Some software will often require users to enter a random password (or check code) sent by a system to verify the identity of the user and prevent malicious login.

Requires C language to generate a set of 6-bit random cipher strings.

Introduction to the RAND function

The RAND function is a true random number generator, which returns a range of random values between 0 and Rand_max (2147483647).

The function is prototyped as: int rand (void);

When using this function, include the header file "Stdlib.h".
