Through the week 1 studying, I learn that
int a;
a=printf("ABC");
will cause a equal 3. Then I am curise that if I use this new thing with char ,what the result will be. So I do a test
char a;
a=printf("ABC");
There is no suprise for the result. It prints ABC. But another question came to my mind. Why it prints ABC instead of just A? I remember that a char can only be stored the first income character and the rest will be eliminated,if it's not a array.
I am still attempting to figure out the reason.

here is the reference of printf
ReplyDeleteprintf returns the total number of characters it has written.
in your case, "ABC" was printed by you printf function, and you char a stores the return value of printf which is integer 3.
if you call char a="ABC", that will be the same as you say. The char a stores the first income character and the rest will be eliminated.
