The printf() function will return the number of characters printed. But in the code below why is it printing 5.
int a=1000; printf("%d",printf("\n%d",a)); It prints "1000" once and a space, so altogether we have 2 characters.
It should output "1000 2". But its outputting "1000 5".

printf() - printf() returns the number of characters successfully written on the output. It is used to simply print data in the output. scanf() - It returns the number of data items that have been entered successfully.
scanf returns EOF if end of file (or an input error) occurs before any values are stored. If any values are stored, it returns the number of items stored; that is, it returns the number of times a value is assigned by one of the scanf argument pointers.
printf() returns total no. of character printed on console, you pass 1000; so first inner printf() function will work and print 1000,and here no. of character is 4.
1) Return type and value of printf function h, it is used to display messages as well as values on the standard output device (monitor). printf returns an integer value, which is the total number of printed characters. For example: if you are printing "Hello" using printf, printf will return 5.
The number of characters output is 5. 1000 is four characters. \n is one character.
printf doesn't return the number of "items" output like the scanf family of functions do for input. It returns the actual character count.

The inner call happens first, prints 5 characters (\n, 1, 0, 0, 0) and returns 5.
The outer call then happens, and prints the 5 that was returned by the inner call.
