C and C++ do not support comparisons of character arrays with the ==
operator, nor with any of the comparison operators. Instead, use the
strcmp() function:

============================================
#include <stdio.h>
#include <string.h>
char name[80];			// <- note the "80"
main()
{
printf ("Write your name:");
scanf ("%s",&name);
if ( strcmp(name,"John") == 0 ) printf ("hello John");
else printf ("Error");
}

To ignore case sensitivity, use stricmp().
