Following is the expression written in "Bash script" (mixture of commands):
^\d{5}(?:[-\s]\d{4})?$
Explanation:
- ^ = For staring string (denotation).
- \d{5} = Matching 5 digits (first five unknown x's)
- (?:…) = Making Group (making group of former 5 digits)
- [-\s] = Match a hyphen or a space
(checking if a hyphen is present?)
- \d{4} = Matching 4 digits (next four unknown x's)
- …? = Pattern before it is optional
- $ = Ending of the string.(denotation)
Explanation:
#include <iostream.h>
#inlcude<conion.h>
void main()
{
int count, x;
clrscr();
cout<<"Enter the count:";
cin>> count;
cout<<"Ready!\n";
for(x=count;x>0;x--)
{
cout<<x<<"\n";
}
cout<<"Start";
getche();
}
This is a simple program where the output is expected to be in reverse order. So we run a for loop starting from the count and decrements the counter by 1 every time when the loop runs and print the value. So to print the output in "new line" we include "\n".
