Question

4. How many times will the print statement be executed within the following nested for loops? Briefly explain how or show the math to calculate that number of iterations.
for (int h = 1; h <= 12; h++) {
for (int m = 0; m <= 59; m++) {
for (int s = 0; s <= 59; s++) {
System.out.printf(“%d:%02d:%02d%n”, h, m, s);
}
}
}

Answer 1

Print statements are used to display outputs

The number of times the nested loop will be executed is 43200

What are nested for loops?

Nested for loops are loops that are placed within another loop or loops

From the statement, we have the following loop conditions:

h = 1; h <= 12, m = 0; m <= 59 and s = 0; s <= 59

The above means that:

• h = 12 --- the outer loop will be executed 12 times
• m = 60 --- the middle loop will be executed 60 times
• s = 60 --- the inner loop will be executed 60 times

So, the number of times the nested loop will be executed is:

$Count = 12*60 *60$

$Count = 43200$

Hence, the number of times the nested loop will be executed is 43200
