{	Indicates the beginning of the main function.

What is \%d in C programming?

In C programming language, \%d and \%i are format specifiers as where \%d specifies the type of variable as decimal and \%i specifies the type as integer. In usage terms, there is no difference in printf() function output while printing a number using \%d or \%i but using scanf the difference occurs.

In the C programming language, scanf is a function that reads formatted data from stdin (i.e, the standard input stream, which is usually the keyboard, unless redirected) and then writes the results into the arguments given.

What is ++ i and i ++ in C?

In C, ++ and — operators are called increment and decrement operators. They are unary operators needing only one operand. Hence ++ as well as — operator can appear before or after the operand with same effect. That means both i++ and ++i will be equivalent. So, value of i is assigned to i before incrementing i.
