Question

How many times the if statements are executed in the code snippet below? for (int i=0; i<20; i++) { if (i%3 == 0) if (i%2 == 0 ) { sum t= 1; }

a) 27
b) 40
c) 20
d) 100

Answer 1

The if statements in the code snippet are executed 6 times.

Step-by-step explanation:

The code snippet contains a for loop that iterates from 0 to 19. This means that it will execute 20 times. Inside the for loop, there is an if statement that checks if the current value of 'i' is divisible by 3 using the modulus operator (%).

If the condition is true, it executes another if statement to check if 'i' is divisible by 2. If both conditions are true, a sum variable is assigned the value 1.

Since every iteration of the for loop executes the if statements, the number of times the if statements are executed can be calculated by counting the number of times the conditions are true. In this case, when 'i' is divisible by both 3 and 2, the conditions are true, so the if statements are executed.

In the range from 0 to 19, there are 6 values (0, 6, 12, 18) that are divisible by both 3 and 2. Therefore, the if statements are executed 6 times.
