How many Library functions are there to allocating the memory dynamically in C?

Question

Does there exist any way to make the command line arguments available to other functions without passing them as arguments to the function in C programming?

Answer 1

There are four library functions in C for dynamic memory allocation and these are as follows -

malloc() - Allocates requested size of bytes and returns a pointer first byte of allocated space.
calloc() - Allocates space for an array elements, initializes to zero and then returns a pointer to memory.
free() - dellocate the previously allocated space.
realloc() - Change the size of previously allocated space.
