The limitation of this, of course, is that it's just pointer pointing to the same memory as argv[1]. That doesn't matter since argv[1] isn't going to change and str1 won't be edited.
They are 'const' so that you can't edit them by accident, it'd be a compiler error (or a lot of intentional typecasting) to try. Any string parameters your functions take which don't get edited should be 'const' too, to signify this. For example:

STRCPY(3) Linux Programmer's Manual STRCPY(3)
NAME
strcpy, strncpy - copy a string
SYNOPSIS
#include <string.h>
char *strcpy(char *dest, const char *src);
'src' for strcpy will accept both constant and non-constant strings because of this, but if you try to put a constant string into 'dest', it will cause a compiler error. This is better than a crash later.
str1="this oracle data base record"
str2="one two three four five"
Output:
this one
oracle two
data three
base four
record five
str1 and str2 have the same column but they are not fixed columns.

Hello all,
I have a question about what you think the best practice is to determine what region you are running on when you have a system setup with a DEV/TEST, QA, and PROD regions running the same scripts in all.
So, when you run in DEV, you have a different directory structure, and you... (4 Replies)

strcpy
STRCPY(3) Linux Programmer's Manual STRCPY(3)NAME
strcpy, strncpy - copy a string
SYNOPSIS
#include <string.h>
char *strcpy(char *dest, const char *src);
char *strncpy(char *dest, const char *src, size_t n);
DESCRIPTION
The strcpy() function copies the string pointed to by src (including the terminating ` ' character) to the array pointed to by dest. The
strings may not overlap, and the destination string dest must be large enough to receive the copy.
The strncpy() function is similar, except that not more than n bytes of src are copied. Thus, if there is no null byte among the first n
bytes of src, the result will not be null-terminated.
In the case where the length of src is less than that of n, the remainder of dest will be padded with nulls.
RETURN VALUE
The strcpy() and strncpy() functions return a pointer to the destination string dest.
BUGS
If the destination string of a strcpy() is not large enough (that is, if the programmer was stupid/lazy, and failed to check the size
before copying) then anything might happen. Overflowing fixed length strings is a favourite cracker technique.
