What's the difference between printf("%i") and printf("%d")
c, printf
Solution
There is no difference.
From the C99 standard document, section 7.19.6.1:
d, i
The int argument is converted to signed decimal in the style [−]dddd. The precision specifies the minimum number of digits to appear; if the value being converted can be represented in fewer digits, it is expanded with leading zeros. The default precision is 1. The result of converting a zero value with a precision of zero is no characters
