In order to keep the plane travelling at a constant speed, an automatically controlled feedback loop is more reliable.
<u>Explanation:</u>
The main reason behind this is that the plane needs to travel at a constant speed and that would only be maintained by setting constant feedback for the loop.
The feedback being constant will correspond to constant input which will, in turn, correspond to a constant output and hence constant speed.
In the case of using a manually controlled feedback loop, feedback will have to be provided manually at each iteration which is not practically viable as there is a scope for errors.
Answer:
There are two ways to print 1 to 1000
- Using Loops.
- Using Recursion.
Explanation:
Using loops
for(int i=1;i<=1000;i++)
{
cout<<i<<" ";
}
Using recursion
Remember you can implement recursion using a function only.
void print(int n)
{
if(n==0)
return;
print(n-1);
cout<<n<<" "';
}
you should pass 1000 as an argument to the function print.
