int n = 33;// define variable n and set it to 33
while(n>= 3) // while n more then 3 or equal
{
cout<< n << " "; // print n
n-= 3; // subtract 3 from n
}
}

b)
#include<iostream>

usingnamespace std;

intmain()
{
charc = 'A'; // define variable c and set it to 'A'
while(c<= 'Z') // while c less or equal to 'Z'
{
cout<< c << " "; // print c
c++;// increment c
