Why is the Character Array not equal to a normal string?

Question

C++ / C#

char var[] = {'a', 'b', 'c', '\0'};
char var2[] = "abc";

if (var == var2)
{
  printf("%s\n", "all is ok !"); 
}

Answer 1

Because your code is comparing pointers (memory addresses for strings in var and var2).
To compare strings, there are the strcmp functions (and its variations).
