i think i've got relatively easy problem here on hands, having trouble getting work. let me preface saying i'm new dax. consider following powerpivot data model : it consists of sales records table, joined date lookup table, "daily expenses" table. "daily expenses" table stores single value represents averaged cost of running specific trading location per day. it's extremely easy produce pivottable provides me total sales amount per store per [insert date period]. i'm after dax formulation calculate profit per store per day - ie. total sales minus dailyexpenses (operating cost): in theory, should pretty easy, i'm confused how utilise dax row context. failed attempts: profit:=calculate(sum(salesinformation[saleamount] - dailystoreexpenses[dailyexpense])) profit:=calculate(sum(salesinformation[saleamount] - dailystoreexpenses[dailyexpense]), dailystoreexpenses[storelocation]) profit:=sum(salesinformation[saleamount] - relate...

hi im writing code resize dynamically allocated memory. here part of code initializing: int size = 1; string *rev = new string[size]; resizing part: if (j >= size / 2){ size = size * 2; string *temp = rev; rev = new string[size]; memcpy(rev, temp, (size / 2)*sizeof(string)); delete[] temp; // <- here causes error! } when comment out "delete[] temp" code works fine memory leaks. so, how can handle error message "assert". please help! thanks! since pointed out assert caused other parts of code. here full version, print words out in reverse order in given sentence. void reversewords(string &sentence) { char *str = new char[sentence.size()+1]; int size = 1; string *rev = new string[size]; int j = 0; int n = 0; int m = 0; (unsigned int = 0; < sentence.size(); i++){ str[n] = sentence.at(i); n++; if (str[n-1] == ' '){ str[n-1] = '\0'; if (j >= size / 2){ ...
