Question

What is the value of count after this nested FOR loop executes fully.

Answer 1

Answer:

168 (although the =< must be corrected to <=)

Explanation:

int count = 0;

for (int row = 4; row <= 15; row++)

for (int col = 0; col < 13; col = col +2)

count+=2;

The inner for loop runs 7 times (for col = 0,2,4,6,8,10,12). Anything higher is not less than 13. Therefore the inner loop increments count by 2 seven times, i.e. it increments count by 14.

The outer for loop runs 12 times (for row = 4,5,6,7,8,9,10,11,12,13,14,15).

If the count is incremented by 14 twelve times, you are incrementing it by 14*12 = 168.

Therefore the count goes from 0 to 168 after the nested loops.
