The rand function returns a pseudorandom integer in the range 0 to RAND_MAX (32767). Use the srand function to seed the pseudorandom-number generator before calling rand. The rand function generates a well-known sequence and isn't appropriate for use as a cryptographic function. For more cry...

Therand() function returns a pseudo-random integer in the range 0 toRAND_MAXinclusive (i.e., the mathematical range [0,RAND_MAX]). Thesrand() function sets its argument as the seed for a new sequence of pseudo-random integers to be returned byrand(). These sequences are repeatable by...
