Return Value of printf() in C: If successful, the total number of characters written is returned. On failure, a negative number is returned. Reference: https://www.tutorialspoint.com/c_standard_library/c_function_printf.htm

01 is result of two printf() In the first line printf() prints 0, without new line Then printf("0") returns the length 1, and store in n The second line print n which is 1 So output is 01
