c - Difference between ++*argv, *argv++, *(argv++) and *(++argv) -

currently learning c , trying head around these instructions. different?

++*argv *argv++ *(++argv) *(argv++)

thanks!

it's postfix increment operator has higher precedence pointer de-reference operator, not prefix increment. these 2 equivalent:

*p++ *(p++)

the prefix increment has same precedence *, *++p increments pointer, , same *(++p). also, ++*p same ++(*p).

c arrays pointers command-line-arguments
