FAST HELP NEEDED!!!!!!

I am new to the C language....... This is my problem:
I need to write a C program to read in a persons name. The name will be passed to me in this format
FName | LName
If I was able to prompt for first name and last name that would no problem but in this situation I can't. I need to read in the single string and and store the fname and lname.

This is what I currently have which is not working because I have incompatible types and comparison between pointer and integer errors, I'm sure there is a better way to do this instead of these if statements. I was thinking of sscanf but i'm not 100% sure how to use this, like I said I am new to C.

Here is my code its a very simple program (it should be):
main()
{

char buff[50];
char fname[25];
char lname[25];
int pipe = 0;
int k = 0;
memset(fname, '\0', sizeof(fname));
memset(lname, '\0', sizeof(lname));

while (gets(buff) != EOF)
{
gets(buff);
fname = ' ';
lname = ' ';

while (k <= length(buff))
{
if (buff[k] =='|')
pipe = 1;
if ((pipe = 0) && (buff[k] != '|'))
fname = fname + buff[k];
if ((pipe = 1) && (buff[k] != '|'))
lname = lname + buff[k];
k++;
}
}

printf("%s%s%s" , fname, lname, fname"."lname"@xxxxxxx.com");
}

PLEASE HELP

PLEASE HELP

Check out the strtok function from string.h in libstdc... You can tokenize the original string using | as a dilimeter. The first token is your first name, second token is your last name...

Also.. that printf statement doesn't look good to me. Are you trying to print out "first last first.last@xxxxx.com"? If so it would look like this: printf("%s %s %s.%s@xxxxx.com\n",first, last, first, last);

if ((pipe = 0) && (buff[k] != '|'))
fname = fname + buff[k];
if ((pipe = 1) && (buff[k] != '|'))
lname = lname + buff[k];

Above is the bug of your program.You must use
fname[k]=buff[k];
to solve this problem.
