in the part where I compare if (arg1 = a) it tells me expression must have a bool type.

Is that not an AND function? ==

jsc42 wrote:

You are trying to compare two strings. The == operator just compares simple scalar values, not arrays.

string vl_reg1[16] = { /* 15 strings */ };
do{
  a = vl_reg1[counter];
  counter = counter + 1;
} while (counter <= 16)
