Question

Integer vecLength is read from input. Given the integer vector averageScores with the size of vecLength, write a for loop to output the integers in the second half of averageScores. Separate the integers with a vertical bar surrounded by spaces (" | ").

Answer 1

To output the integers in the second half of a vector called averageScores, start a for loop at the midpoint of the vector. The loop should print each integer followed by " | ", except after the last element. An example using C++ was provided for clarity.

Step-by-step explanation:

If you have an integer vecLength and a vector averageScores with the size of vecLength, to output the integers in the second half of averageScores, you would start your loop at halfway through the vector. You can calculate the starting index by dividing vecLength by 2. Then, write a for loop starting from that index to the end of the vector. Here's an example in C++:

int startIndex = vecLength / 2;
for(int i = startIndex; i < vecLength; i++) {
std::cout << averageScores[i];
if(i < vecLength - 1) ";

}

This loop will output the integers in the second half of the vector, with each integer separated by a vertical bar and spaces as specified.
