Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards
konstantin123 [22]

Answer:

for(i = 0 ; i < NUM_VALS; ++i)

{

   cout << courseGrades[i] << " ";

}

cout << endl;

for(i = NUM_VALS-1 ; i >=0 ; --i)

{

   cout << courseGrades[i] << " ";

}

cout << endl;

Explanation:

The first loop initializes i with 0, because we have to print the elements in order in which the appear in the array. We print each element, adding a space (" ") character at its end. After the loop ends, we add a new line using endl.

The second loop will print the values in a reverse order, so we initialize it from NUM_VALS-1, (since NUM_VALS = 4, and array indices are 0,1,2,3). We execute the loop till i >= 0, and we print the space character and new line in a similar way we executed in loop1.
