What is the incorrect action and why does it occur?
Specification: Write out Hello World twenty-five times. Each hello begins a new line.
```
#include
using namespace std;
int main()
{
int i = 1;
while(i < 25)
cout << “\nHello World”;
++i;
return 0;
}
```
There are two errors in this code. First, the initial value of i = 1, and the condition statement is running while i < 25. This will result in 24 Hello Worlds, not 25.
However, the real problem is that the while loop does not have { }; therefore, only the cout statement will be performed. The value of i is never incremented.
The fix involves inserting { } and initially setting i to zero.
