Thread: problem with strncat command

The code below supposed to provide
str1 = ilikeyou.c
str2 = .com as str2 should not affect by strncat command
but it shows str1 = iloveyou.c and str2 = c

I wonder why str2 is only c when it supposed to be .com

Code:

main ()
{
char *str1 = "ilikeyou"
char *str2 = ".com"
clrscr ();
printf ("your two lines are \n %s \n %s", str1,str2);
strncat (str1,str2,2);
printf ("\nYour new two lines are \n %s \n %s", str1,str2);
getch ();
return 0;
}
