Answer:
2
Explanation:
if-else is the statement that is used for checking the condition and if the condition is True, then execute the statement otherwise not executed.
initially, the value of n1 = 3, n2 = 6, n3 = 2, sumtotal = 4.
after that, if statement checks for the condition.
3 != 4
condition is TRUE, then the statement sumtotal -= n3; will be executed.
write the statement in simple form:
sumtotal = sumtotal - n3;
so, sumtotal = 4-2 = 2.
after that, the program does not check the further and exit the if-else statement.
Therefore, the answer is 2.
