WebThe pseudo-random number generator is initialized using the argument passed as seed. For every different seed value used in a call to srand, the pseudo-random number generator can be expected to generate a different succession of results in the subsequent calls to rand. Two different initializations with the same seed will generate the same … WebA block of memory previously allocated by a call to malloc, calloc or realloc is deallocated, making it available again for further allocations. If ptr does not point to a block of memory allocated with the above functions, it causes undefined behavior. If ptr is a null pointer, the function does nothing. Notice that this function does not change the value of ptr itself, …
