Confusion about the output

Question

#include
int main(void)
{
    int i=1,j=-1;
    if((printf(\"%d\",i))<(printf(\"%d\",j)))
        printf(\"%d\",i);
    else 
        printf(\"%d\",j);         


        

Answer 1

For -1 number of characters printed is 2 hence if condition is satisfied.

Answer 2

I think it is rather obvious: '1' is one character, '-1' is two. One is less than two.

Answer 3

Because printing j prints "-1", that's two characters. so 1<2 is true.

Answer 4

printf returns the number of characters (not just digits) written.

So printf("%d",-1) will return 2 not 1

Similarly printf("%d",1) will return 1

Making the condition in the if true.
