Answer:
The correct answer is:
C. ndx = 0;
while (ndx < 3) {
ar[ndx] = 0;
ndx++;
}
Explanation:
The declaration given is:
int ar[3];
This means the array consists of three locations and is named as ar.
We know that the indexes are used to address the locations of an array and the index starts from 0 and goes upto to 1 less than the size of the array which means the indexes of array of 3 elements will start from 0 and end at 2.
Now in the given options we are using ndx variable to run the while loop.
So the code to assign zero to all elements of array will be
ndx = 0;
while(ndx<3)
{
ar[ndx] = 0;
ndx++;
}
Hence, the correct answer is:
C. ndx = 0;
while (ndx < 3) {
ar[ndx] = 0;
ndx++;
}

Answer:
Choose what you think based on this.
Explanation:
with a for loop:
>>> students = 3
>>> for student in range(students):
>>> print(student)
would output
>>> 0
>>> 1
>>> 2
with a while loop now:
>>> students = 3
>>> student = 0
>>> while student < students:
>>> student = student + 1
>>> print(student)
the for loop is more compact than the while loop. But there may be some times when a you cant do a for loop. The first question is more than likely definite but I don't know the second answer.
