Question
Using C programming. Eclipse: I have the following code but I have run into some issues, first when it comes to the user inputting more than once seat I cannot make it show that multiple seats are taken and to output that _ number of seats have been taken at row __ and column __ and contine it until the number of seats selected have been chosen. I also want it the chart to update everytime a ticket(s) are purchased and give me the total ticket prices. It should keep track of the ticket sales, and the user should be given that option to see tht. Another thing is tht the program should give the user an option to see how many seats have been sold, seats available in each row, and seats available in the whole theater. to be more cleat I attached a picture of my instructions
void mapSeats (int i, int j, char sts[][30])
{
// char TAKEN = '*';
// char EMPTY = '#';
int rw = 15;
int col = 30;
printf (" Seats ");
fflush (stdout);
printf (" 012345678901234567890123456789");
fflush (stdout);
for (i = 0; i < rw; i = i + 1) {
printf (" Row %2d ", i);
fflush (stdout);
for (j = 0; j < col; j = j + 1) {
printf ("%c", sts[i][j]);
fflush (stdout);
}
}
putchar (' ');
}
void theatre (void)
{
int row = 15;
int column = 30;
float prices[15];
char sts[row][column];
char TAKEN = '*';
char EMPTY = '#';
int reserve;
int i = 0;
int j = 0;
int k=0;
// float cost;
// int static total;
printf ("Enter the price for each row of seats. ");
fflush (stdout);
for (row = 0; row < 15; row = row + 1) {
printf ("Row %2d: ", row);
fflush (stdout);
scanf ("%f", &prices[row]);
}
// printf("What would you like to do? Select a number: ");
// printf("1: Reserve seats");
// printf("2: View total ticket sales");
// printf("3: View sold and available seats");
for (i = 0; i < row; i = i + 1) {
for (j = 0; j < column; j = j + 1) {
sts[i][j] = EMPTY;
}
}
mapSeats (i, j, sts);
printf (" How many seats would you like to reserve? ");
fflush (stdout);
scanf ("%d", &reserve);
printf ("Enter the row and column number for the desired seat(s). ");
fflush (stdout);
for (k=1 ; k <= reserve; k=k+1) {
scanf ("%d %d", &row, &column);
printf (" You have selected Row %d, Column %d ", row, column);
fflush (stdout);
for (i = 0; i < 15; i = i + 1) {
for (j = 0; j <= 30; j = j + 1) {
if (row == i && column == j) {
sts[i][j] = TAKEN;
}
}
}
}
mapSeats (i, j, sts);
}
int main (void)
{
theatre ();
return 0;
}
