Hi,
there is just a subtle difference between passing a i
nteger pointer and integer array, look below,
a) char fun(int *quantity)
and while calling you should be giving the address of the variable like fun(&n);
b) now, to pass an integer array, 2 options are there, you can pass the exact same like above i.e
char fun( int *a) OR
char fun( int a[])
both are identical;
arrays cannot be passed by value,
the difference comes in both a and b is how you are defining the passig value.
for example in a. you can right
int n;
and call fun(&n) – here you are passing an integer pointer
for b
int a[]={0,0}
fun(a) — here you are passing the integer array.
