to output in decimal notation of a char variable, we write like this
1 2 | char a1 = 'a'; printf("a1 is [%d].\n", a1); |
in the way we output an int variable.
but when we output a long variable, we must write like below reluctantly
1 2 3 | #need to test in gcc. long l1 = 123456789; printf("l1 is [%ld].\n", l1); |
don't say byte alignment.
