getting characters from a string that...

has been put into a variable. I need some advice or help on how to get the first two characters from what has been put into a variable using sscanf. I know it doesn't matter how the data was put there but I thought I would mention it anyway.

partial example of my code that works except what I need to do:

void main()
{

#define MAXLINE 128

FILE *fr;

char s5[10];
char line[MAXLINE];

if(fgets(line, MAXLINE, fr) != NULL) {
sccanf (line, "%6c", s5);
pId->Wx_Id = s5;

// Here is what I don't know how to do
pId->Temp = first 2 characters in s5

exit(0);
}

}


Thanks for your help!

>void main()
Wrong, use int main(void), as main returns an int.

>FILE *fr;
>if(fgets(line, MAXLINE, fr) != NULL) {
At what point did you open fr?

If you want to copy n chars from one array to another, lookup the strncpy() function.

Sorry I didn't put all the code in. I have the file opened and I am reading it correctly. I just don't know how to get the first 2 characters from the one variable into the other.

Hammer,
Thank you for your help. I used the strncpy function and it did exactly what I wanted. Also, I visit this board often and review several posts each day, and without a doubt you offer the best help. You don't just give away answers you make people think (but you do it in a way that does not offend others...unlike Salem's responses).
Cheers!

OK, just to ensure you fully understand how to use strncpy(), here's a small, but complete, program.

Code:

---

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

int main(void)
{
    char name[] = "Hammer";
    char twochars[3];
   
    strncpy (twochars, name, 2);
   
    printf ("%s", twochars);
   
    return 0;
}

It is supposed to print out the first two characters, eg Ha. But it has a bug, can you see it?
