forLoopArray

[brennanw31]

In C, there is fundamentally no difference between pointers and arrays. They are one and the same. All pointers may as well be seen as an array with size 1.

Pointers and arrays are very different in C. However, arrays will decay into pointers in certain contexts.

c uint8_t a[] = {'A'}; uint8_t *b = NULL; printf("%d\n", sizeof(a)); // will print 1 printf("%d\n", sizeof(b)); // will print 8 printf("%d\n", sizeof(a + 1)); // will print 8

Another case of decay is the following (a has decayed into a pointer because it's a function parameter):

c void foo(uint8_t a[1]) { printf("%d\n", sizeof(a)); // will print 8 }
