Answer :
As per the concept of vector, the while loop for integers is written below.
The term vector refers a quantity or phenomenon that has two independent properties: magnitude and direction.
Here we need to write the a quantity or phenomenon that has two independent properties: magnitude and direction.
While we looking into the given question, we have know that,
Here the input is 1 6 5 3 -1, then
the output is: 1 6 5 3
Then the function for the given statement is written as,
while ((char1 = getchar()) != '-1')
{
if (char1 == ' ')
sp_ct1++;
else if (char1 == '\n')
nl_ct1++;
else
other1++;
}
Therefore, the above function is used to read integers from input until -1 is read.
