Explanation / Answer

please rate - thanks it now sorts. remember to enter the file name asegr126.txt. you can't sort 20 numbers if you only have 10,and it was doing largest to smallest. I added range of numbers and largest numbers. I can help with the rest of the program but I need to know ifyou've learned functions yet #include #include #include #include using namespace std; int main() { string filename, egr126("egr126"); int loop=20, ID, count, m, hod; double grade, hold,average; ifstream AAA; ofstream BBB; int id [20]; double GRADE [20]; cout ID;    count++;     }; loop=count; for (int k=0; k
