How to display a count

mim97 (24)
//input two integers a and b. find out small and big values between a and b.
//Example if a is 12 and b is 5 then small will be b and big will be a.
//Use a loop to output multiples of 3 from small to big.
//Display their count and sum


The program works fine but i cant display the count of the multiples of 3.

The problem here is your if statements need braces to include 2 lines of code.
