In main, you will read in an input filename and re-prompt until a valid input file is read, once the filestream could be opened, you will read the file, the file will contain the following: an integer that denotes the amount of test cases (or the amount of streets the hamburglar will hit), then for each test case, there will be an arbitrary series of numbers that denotes the amount of hamburgers in a restaurant, each test case will be terminated with -1. then for each test case, output the max number of hamburgers the hamburglar can steal from that street. the amount of restaurants on the street is unknown, thus you will need to have a pointer that will constantly resize the dynamic array, we also want to save memory so you don’t want to allocate too large of an array, so allocate an array of size 5 and everytime the array fills up, allocate 5 more elements to the array. you may need to deallocate the array after each test case is finished.
