calloc
// declare a pointer variable to point to allocated heap space
int *p_array;
double *d_array;
// call malloc to allocate that appropriate number of bytes for the array
p_array = (int *)malloc(sizeof(int)*50); // allocate 50 ints
d_array = (int *)malloc(sizeof(double)*100); // allocate 100 doubles
// use [] notation to access array buckets
// (THIS IS THE PREFERED WAY TO DO IT)
for(i=0; i < 50; i++) {
p_array[i] = 0;
}
// you can use pointer arithmetic (but in general don't)
double *dptr = d_array; // the value of d_array is equivalent to &(d_array[0])
for(i=0; i < 50; i++) {
*dptr = 0;
dptr++;
}

// The Malloc way
void *ptr = malloc(sizeof(Type) * n_elem);
// The Calloc way
void *ptr = calloc(n_elem, sizeof(Type));
Thank you!
