I am trying to write a programed named reverse.c that echoes its command-line arguments in reverse order. But i don't know what is wrong.
If the input is: reverse void and null
The output should be: null and void
Code tags added by Kermi3.Code:#include <stdio.h> #define N 100 main(int argx, char *argy[]) { int i=0, k; char *p[100]; printf("Enter a sentence: "); gets(argy[100]); i++; for(k = i-1; k >= 0; k--) printf("%s", argy[0]); return 0; }
I am posting this because you did not use code tags on this thread. In the furture please use Code Tags. They make your code MUCH easier to read and people will be much more likely to help you if you do. And they'll be happy about helping you
For example:
Without code tags:
for(int i=0;i<5;i++)
{
cout << "No code tags are bad";
}
With Code Tags:
This is of course a basic example...more complicated code is even easier to read with code tags than without.Code:for(int i=0;i<5;i++) { cout << "This code is easy to read"; }
I've added code tags for you this time. They can be added by putting [code] at the beginning of your code and [/code] at the end. More information on code tags may be found at the link in my signature. Any further questions or ways I can help please feel free to PM me.
Good Luck,

Sorry to say, but you don't seem to understand the command line concept.
Here's some pseudo code to help you out.
check number of arguments
then simply print the strings from the last to the 1st argument using the above info
Questions to consider
- How do I know what the last string is?
- Where is the first string?
You can code this without declaring any variables.
Try not.
Do or do not.
There is no try.
