There are basically two ways of calling sizeof:
sizeof unary-expression sizeof ( type-name ) Parentheses is not bad, when you are not sure whether to add it or not, just add it. For your case, you should put parentheses around type int, and also you can leave arr without parentheses. In total, you can use below two ways to express: sizeof(arr) / sizeof(int) sizeof arr / sizeof(int) Or simply sizeof arr / sizeof arr[0] *Reference:* http://msdn.microsoft.com/en-us/library/4s7x1k91(v=VS.100).aspx http://en.wikipedia.org/wiki/Sizeof -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
