Answer:
The answer is 100 because the range() function in the for loop is set to go from 1 to 100, not 1 to 101. The range() function is inclusive of the start value and exclusive of the end value, so in this case it will only go up to 99, not 100. Additionally, the counter variable is not being incremented correctly within the for loop. The correct syntax for incrementing a counter variable would be "counter += 1" instead of "counter = counter + 1".
