Explanation / Answer

please rate - thanks would you believe the line in red was omitted //Airplane seat assignment #include #include using namespace std; const int MAX_ROW = 7; const int MAX_SEAT = 4; void chooseseat(char[][MAX_SEAT]); void purchase(int,int,char[][MAX_SEAT]); void clearseats(char[][MAX_SEAT]); void display_seating(char [][MAX_SEAT]); bool assign_seat(char [][MAX_SEAT], int rows, int row, intcol); int main() { int row, col; int input_row,left; left=MAX_SEAT*MAX_ROW; char seat[MAX_ROW][MAX_SEAT],more='Y'; clearseats(seat); display_seating(seat); while(left>0&&toupper(more)=='Y') {chooseseat(seat); left--;    display_seating(seat);    coutmore; } system("pause"); return 0; } void clearseats(char seats[][MAX_SEAT]) {int i,j; for(i=0;i
