Your missing a '}' in your if statement. Check right before the else.

Thanks for the reply. I have added } but still got the problem.

Error message :
1.error C2059: syntax error : '&&'
2.error C2143: syntax error : missing ';' before '{'
3. error C2181: illegal else without matching if

#include <stdio.h>
int main (void)
{
int c;

printf("letter=");
c = getchar ( );

if (('0' <= c && c <= '9') || ('A' <= && c <='F') || ('a' <= c && c <='f')){
	printf ("It is a hexadecimal\n");
}
else {
printf (" It is not a hexadecimal\n");
}

return 0;

}

Read ('A' <= && c <='F') over. Something's amiss.
