Block Sum Check

It's probably easy for most of you but ... is there and easy way to get a BSC from a char array ... ex.: char buffer[20]; ?

thank you !

You mean like using a for loop to subscript the elements of your array?

If I understand the explanations, I have to loop and do an addition with the binary value of each char (on the client side and on the server side). Then I'll know if this is the same exact value.

ex:

a[0] = 'A';
a[1] = 'B';
a[2] = 'C';
a[3] = 'D';
a[4] = 'E';
a[5] = 'F';


A + B + C + D + E + F = something

Any way to do this ?

Code:

---

int sum = 0;
for(int i = 0;i < 6;++i)
  sum += a[i];

---

You mean like that?

Humm if we can add char value into an int, I'll try this ... thanks

A char value is just a small (1 byte) data type. The character representation (e.g. 'A' or 'B') is just a convenience for the programmer. The character constants just map to the underlying character set which translates it into a value.

I think that the formula as was looking for looks like ...

BSC = 0;
BSC ^= a[0];
BSC ^= a[1];
.

then i will need to get a string out of BSC
