C Random Number Generation: rand() & srand()

In C language, you can generate random numbers using the rand() function. This function is defined in the stdlib.h header file with the following prototype:

Generate a random number.

Furthermore, you can also use the srand() function to set the seed for random numbers, ensuring that each generated random number sequence is different every time. This function is also defined in the stdlib.h header file, with the following prototype:

Initialize the random number generator with a specified seed.

It is important to note that the random numbers generated by the rand() function are pseudo-random and their sequence can be repeated. For higher quality random numbers, consider using the random number generation functions provided by the operating system.
