char * a, * b;
b = new char;
a = new char;
int len, le;
le = 0;
cout<< " enter your string \n";
cin>> a;
len = strlen(a);
for(int i = len-1; i>=0 ; i--)

Can we print any string in reverse order?
For example:
oracle 16294 1 0 Aug 11 ? 0:00 ora_reco_crepd
oracle 16276 1 0 Aug 11 ? 0:19 ora_dbw0_crepd
I need second last column from this output. (0:00 & 0:19).
I can use awk print $2 after reversing the string.

Guys,
I am trying to find a way to achieve this. I need to print /usr/local/apche/htdocs only from the string /usr/local/apache/htdocs/file.php using the regex. The below did not work. I know a solution with normal cut, I need a way to do this with the awk regex.
awk '/+file.php/' (6 Replies)
Hi All,
I have a String str="Manish". I would like to reverse it.
I know the option to do this in bash is: echo "Manish" | rev
but I have seen an alternate solution somewhere, which states that:
str="Manish" echo $str | awk '{ for(i=length($0);i>=1;i--) printf("%s",substr($0,i,1));... (7 Replies)
Hello,
Can anyone explain for me in this script to reverse the string?
1) the "x=x" part, how it works?
$ echo welcome | awk '{ for(i=length;i!=0;i--)x=x substr($0,i,1);}END{print x}'
$ emoclew2) x seems to be an array at the END, but can it automatically print the whole array in awk?
Thanks... (8 Replies)

NAME
strlen - get string length
SYNOPSIS
#include <string.h>
size_t strlen(const char *s);
DESCRIPTION
The strlen() function shall compute the number of bytes in the string to which s points, not including the terminating null byte.
RETURN VALUE
The strlen() function shall return the length of s; no return value shall be reserved to indicate an error.
ERRORS
No errors are defined.
The following sections are informative.
EXAMPLES
Getting String Lengths
The following example sets the maximum length of key and data by using strlen() to get the lengths of those strings.
#include <string.h>
...
struct element {
char *key;
char *data;
};
...
char *key, *data;
int len;
*keylength = *datalength = 0;
...
if ((len = strlen(key)) > *keylength)
*keylength = len;
if ((len = strlen(data)) > *datalength)
*datalength = len;
