trace (1 + 1); RESULT 2

nNum1 = 3;
nNum1 += 1; RESULT 4

nNum[] = "book1, book2, book3"; RESULT from trace(nNum[0]) book1

nNum = 5
if (nNum > 5 || nNum == 5) { - if nNum is greater then 5 or nNum is same as 5

nNum = 5 * 5; RESULT 25

//nNum = 5; <-- line disabled. passed as a comment

trace (12%5); RESULT 2

i = 1;
i++; RESULT i = 2;
