what is wrong in the following program?

I'm trying to split the ip addresses using c and check if each fields are below 255(validity)It shows several errors help me out..

insert

Code:

---

#include <stdio.h>
#include <string.h>

struct
{
int vty;
char a;
char b;
char c;
char d;
} ip[10]

main()
{
        int i,x;
        char st[15];
                printf("Enter the number of ip address: ") ;
                scanf("%d",&x);
        for(i=0;i<x;i++)
{
                printf("Enter the ip address: ");
                scanf("%s",&st[i]);

                sscanf(st[i],"%s.%s.%s.%s",&ip[i].a,&ip[i].b,&ip[i].c,&ip[i].d);
                printf("%s.%s.%s.%s",ip[i].a,ip[i].b,ip[i].c,ip[i].d);


        if ((a!<256)&&(b!<256)&&(c!<256)&&(d!<256))
{
                printf("Enter a valid ip !");
                i--;
}
}

%s scans strings
%c scans one character
%d scans an integer (why aren't you just using this?)
Your struct has single characters.
You don't actually have any variable called a (or b or c or d).
You don't apparently pay attention to your compiler at all.


Quzah.

why don i have a variable called a?
I accept al other mistakes.

Code:

---

if ((a!<256)&&(b!<256)&&(c!<256)&&(d!<256))

You do not have anything called just a. You have a ip[ x ].a but not just a.

Also those comparisons are wrong. You can't do !< as a comparison.
