WebC++ calloc () The calloc () function in C++ allocates a block of memory for an array of objects and initializes all its bits to zero. The calloc () function returns a pointer to the first byte of the allocated memory block if the allocation succeeds. If the size is zero, the value returned depends on the implementation of the library. WebWorking of C++ srand () The srand () function sets the seed for the rand () function. The seed for rand () function is 1 by default. It means that if no srand () is called before rand (), the rand () function behaves as if it was seeded with srand (1). However, if an srand () function is called before rand, then the rand () function generates a ...
